Technical Field

Background

In UGC (User Generated Content ) type games, a player or game developer is free to edit the game scene. In the process of editing a game scene, a selected state effect of displaying a virtual object (Entity) has an important meaning for a player to clearly and currently operate the virtual object. In general, the selected state effect of presenting the virtual object in the virtual scene may be presented by tracing the outer contour of the selected virtual object to enhance the visibility of the virtual object in the game scene.

In the related art, displaying the description effect in the game scene requires two times of rendering of the model, in the first time of rendering, vertex coordinates of the model are extended outwards along a normal direction, description colors are used for rendering, and in the second time of rendering, original vertices of the model are normally rendered. Then, the result of the second rendering is covered with a part which is repeated with the result of the first rendering, so that the width of the uncovered vertex in the result of the first rendering is used as the edge drawing effect.

However, the width of the thus obtained welt may vary with the change in the line-of-sight distance for the game scene, and when the line-of-sight distance is large, the player may not see the welt effect even clearly.

FIG. 1 is a flow chart illustrating a stroked display method according to some embodiments. As shown in fig. 1, an embodiment of the present disclosure provides a method for displaying an edge, which may be performed by an electronic device, and in particular, may be performed by an edge display apparatus, where the apparatus may be implemented by software and/or hardware, and configured in the electronic device. As shown in fig. 1, the method may include the following steps.

In step 110, a virtual scene picture is displayed.

Here, the virtual scene screen includes a virtual scene. A virtual scene is a virtual scene that an application program displays or provides when running on an electronic device, where a virtual scene may refer to a game scene, such as a two-dimensional game scene, a three-dimensional game scene, a virtual reality scene, and so on.

It should be appreciated that the virtual scene picture may be a picture obtained by picture capturing of a virtual scene by a virtual camera.

In step 120, in response to the selection operation for the virtual object in the virtual scene, the outer contour of the virtual object is traced in the image space corresponding to the virtual scene picture, and outer contour tracing of the virtual object is obtained.

Here, the selection operation for the virtual object in the virtual scene may be a click operation, a box selection operation, or the like for the virtual object in the virtual scene. A virtual object may refer to an element used to build an environment in a virtual scene. For example, the virtual object may be a building, tree, etc. model in a virtual scene.

Outlining refers to the additional visual effect added to the outer contour of a virtual object. After a virtual object in the virtual scene is selected, the virtual object is in a selected state, and in order to display the virtual object in the selected state in the virtual scene, an outline description may be added to the virtual object to highlight the selected virtual object in the virtual scene.

The image space of the virtual scene is a two-dimensional space, which is a space composed of the width and the height of the virtual scene. The image space corresponding to the virtual scene refers to an image space that coincides with the image space of the virtual scene.

It is noted that the size of the image space of the virtual scene picture may be determined by the size of the screen used to display the virtual scene picture. Therefore, the outer contour of the virtual object is traced in the image space corresponding to the virtual scene picture, which can also be understood as tracing the outer contour of the virtual object in the screen space.

The virtual object may be rendered into an image space corresponding to the virtual scene picture, and then, in the image space, an outer contour of the virtual object is traced based on a preset tracing width, so as to obtain an outer contour tracing of the virtual object.

It should be noted that the tracing of the outline of the virtual object in the image space corresponding to the virtual scene is not to directly trace the outline of the virtual object in the virtual scene, but to trace the outline of the virtual object in the image space in an image space consistent with the image space of the virtual scene.

It should be appreciated that in embodiments of the present disclosure, the obtained outer contour tracing of the virtual object may be an image that includes the outer contour tracing of the virtual object.

In step 130, the outer contour tracing of the virtual object is superimposed on the virtual scene picture, wherein the width of the outer contour tracing remains unchanged as the virtual scene is scaled.

Here, the outer contour tracing of the virtual object in the selected state may be superimposed on the virtual scene picture, thereby displaying the outer contour tracing of the virtual object in the selected state.

As some examples, the obtained outer contour tracing of the virtual object may be superimposed on an upper display of the virtual scene picture.

As yet other examples, the obtained outer contour tracing of the virtual object may be fused at an upper layer of the virtual scene picture to display the outer contour tracing of the virtual object by displaying the fused virtual scene picture.

That is, in the embodiment of the present disclosure, the outer contour tracing of the virtual object may be superimposed and displayed by one image (the virtual scene picture after fusion), or the outer contour tracing of the virtual object may be superimposed and displayed by two images (the virtual scene picture and the outer contour tracing).

It should be noted that, since the outer contour tracing of the virtual object is obtained by tracing the outer contour of the virtual object in the image space corresponding to the virtual scene picture, even if the size of the displayed virtual object is changed, the width of the outer contour tracing of the virtual object before and after the size change is still the preset tracing width, so that the width of the outer contour tracing of the virtual object remains unchanged when the virtual scene is zoomed.

For example, when a virtual scene is enlarged, the virtual object is enlarged accordingly, which corresponds to a smaller line-of-sight distance between the player and the virtual object, and when the virtual scene is reduced, the virtual object is reduced accordingly, which corresponds to a larger line-of-sight distance between the player and the virtual object. At this time, according to the stroking display method provided by the embodiment of the present disclosure, since the outline stroking is obtained in the image space corresponding to the virtual scene, the outline stroking of the virtual object is related to the image space of the virtual scene, and even if the virtual scene in the virtual scene changes, the width of the outline stroking of the virtual object is not affected. Therefore, by displaying the outer contour tracing of the virtual object obtained from the image space superimposed on the virtual scene image, the width of the outer contour tracing of the enlarged virtual object can be made uniform in player's vision with respect to the width of the outer contour tracing of the reduced virtual object, and it is achieved that the width of the outer contour tracing remains unchanged at the time of scaling of the virtual scene.

It should be noted that, if the outline tracing is performed on the virtual object in the geometric space of the virtual scene, the outline tracing corresponds to a line in the virtual scene, when the virtual scene is zoomed out and zoomed in, the outline tracing is correspondingly zoomed out and zoomed in, so that the width of the outline tracing changes along with the change of the sight line distance, and when the sight line distance becomes gradually larger, even the user cannot see the outline tracing of the virtual object. Moreover, the outer contour tracing is also affected by perspective, resulting in a larger width outer contour tracing at a near location and a smaller width outer contour tracing at a far location.

According to the tracing display method provided by the embodiment of the disclosure, when a player zooms a virtual scene, the zoomed virtual scene is presented through the virtual scene picture, and because the outer contour tracing is obtained in the image space corresponding to the virtual scene picture, even if the player zooms the virtual scene, the width of the outer contour tracing is kept consistent, so that the consistency of the outer contour tracing is ensured.

Therefore, by displaying the virtual scene picture, responding to the selection operation of the virtual object in the virtual scene, carrying out edge tracing on the outline of the virtual object in the image space corresponding to the virtual scene picture, obtaining the outline edge tracing of the virtual object, and superposing and displaying the outline edge tracing of the virtual object on the virtual scene picture, the width of the outline edge tracing can not be influenced when the virtual scene is zoomed, and the outline edge tracing is always kept consistent, so that the consistency of edge tracing effects is ensured.

In some implementations, the outer contour tracing of the virtual object is a complete outer contour tracing of the virtual object when the virtual object is at least partially occluded.

Here, the virtual object being at least partially occluded may mean that a part or all of the virtual object is occluded. FIG. 2 is a schematic diagram illustrating a virtual object being at least partially occluded, according to some embodiments. As shown in fig. 2, in a virtual scene 201, a first virtual object 202 is occluded by a second virtual object 203 and a third virtual object 204. In this scenario, the outer contour tracing 205 of the first virtual object 202 is the complete outer contour tracing of the first virtual object 202.

It should be noted that, the complete outline tracing of the virtual object refers to an outline tracing obtained by tracing a complete outline line of the virtual object. Even if the virtual object is at least partially occluded in the virtual scene, the obtained outer contour tracing is still the complete outer contour tracing of the virtual object.

Therefore, through the embodiment, even if the virtual object in the selected state in the virtual scene is partially or completely blocked by other virtual objects, the complete outline description of the virtual object in the selected state can be displayed, so that the player can clearly identify the virtual object in the selected state in the virtual scene.

FIG. 3 is a flow chart illustrating a stroked display method according to further embodiments. As shown in fig. 3, the following steps may be included.

In step 310, a virtual scene picture is displayed.

Here, the detailed description of step 310 may refer to the related description of step 110 in the above embodiments, and will not be repeated here.

In step 320, the virtual object is rendered to a first image, where the first image is an image constructed based on an image space corresponding to the virtual scene picture.

Here, the virtual object in the selected state in the virtual scene may be individually rendered to the first image. The first image may be an image constructed based on an image space corresponding to the virtual scene picture. That is, the width and height of the first image are consistent with the width and height of the virtual scene picture.

It should be appreciated that the size of the virtual objects in the first image is consistent with the size, presentation angle, etc. of the virtual objects in the virtual scene.

In Unity, the LAYERMASK functions provided by Unity may be used to individually render the virtual object in the selected state into the first image. The virtual object in the selected state may be set as a stroked level, and the level to be drawn is screened by FILTERINGSETTINGS in the DRAWRENDERERS function.

Of course, the CommandBuffer functions provided by Unity may also be used to specify the virtual object in the selected state, thereby rendering the virtual object in the selected state into the first image. Wherein CommandBuffer functions store a series of rendering commands, such as setting a rendering target or drawing a particular grid. Through CommandBuffer functions, custom rendering commands can be inserted and executed at specific points in the Unity built-in rendering pipeline, specifying rendering of specific virtual objects to control rendering flows at finer granularity.

It should be noted that, in the embodiment of the present disclosure, the specific implementation of rendering the virtual object to the first image is not limited, and any game engine or any rendering manner that can be implemented may be used to render the virtual object to the first image.

Fig. 4 is a schematic diagram of a virtual scene screen shown in accordance with some embodiments. As shown in fig. 4, in the virtual scene screen 401, a virtual object 402 is a virtual object in a selected state.

Fig. 5 is a schematic diagram of a first image shown according to some embodiments. As shown in fig. 5, a virtual object 402 in a virtual scene is rendered in a first image 403.

It should be noted that, even if the virtual object in the virtual scene is occluded, the virtual object in the virtual scene is still completely rendered in the first image. By rendering the virtual object to the first image, not only can the outer contour tracing of the virtual object be obtained through the first image, but also the complete outer contour tracing of the virtual object can be obtained.

In some embodiments, the virtual object is rendered to the first image with a solid color, the first image having a color different from the solid color.

The solid color in the embodiments of the present disclosure is used as a material, and the solid color may be used as a material of the virtual object, and then the virtual object with the solid color material is rendered in the first image. Illustratively, the solid color may be white and the first image may be black in color. Of course, the pure color can be other colors, and can be set according to actual conditions.

It should be noted that rendering the virtual object to the first image by using the solid color means that the solid color is used as a rendering material of the virtual object, and then the virtual object of the solid color material is rendered to the first image. Since the solid color does not contain complex texture details, the inner contour of the virtual object in the first image may be weakened. Wherein the inner contour refers to an edge line inside the virtual object, which defines the shape and boundaries of the internal structure of the virtual object. For example, the inner contour may be a void, a groove, or a boundary between different surfaces inside the virtual object. Further, by rendering the virtual object to the first image using a solid color, it is possible to facilitate the subsequent use of color channels to distinguish between pixels belonging to the virtual object and pixels not belonging to the virtual object in the first image.

As shown in fig. 5, a virtual object 402 is rendered in a first image 403 that is entirely black using white material.

In other embodiments, when the number of the selected virtual objects is a plurality of, rendering the plurality of virtual objects to the first image through the same solid color, so as to obtain an outline drawing corresponding to an overall outline formed by the plurality of virtual objects through the first image, wherein the color of the first image is different from the solid color.

The number of the selected virtual objects is a plurality, which means that the number of the virtual objects in the selected state in the virtual scene is a plurality. And rendering the plurality of virtual objects to the first image by using the same solid color, wherein the overlapped parts do not have color difference due to the fact that the plurality of virtual objects use the same solid color, so that the outer contour tracing corresponding to the whole outer contour formed by the plurality of virtual objects can be obtained through the first image.

It should be noted that, the overall outline formed by the plurality of virtual objects may refer to an outline curve formed by the plurality of virtual objects when they are combined together. When the plurality of virtual objects comprise overlapped virtual objects, the whole outline corresponding to the overlapped virtual objects is a closed curve formed by connecting all vertexes of the overlapped virtual objects according to a certain sequence. When the plurality of virtual objects includes non-overlapping virtual objects, the overall outer contour of the plurality of non-overlapping virtual objects is made up of the outer contours of the individual virtual objects. Thus, where the plurality of virtual objects includes overlapping virtual objects and non-overlapping virtual objects, the overall outline formed by the plurality of virtual objects may include a closed curve formed by the overlapping virtual objects and an outline formed by each non-overlapping virtual object separately.

In step 330, a second image is obtained that includes an outline description of the virtual object from the first image.

Here, a pixel position where a tracing is required may be calculated in the first graph, and then a second image including an outer contour tracing of the virtual object may be drawn based on the pixel position.

It should be noted that the second image may be an image constructed based on an image space corresponding to the virtual scene picture. That is, the width and height of the second image may be consistent with the width and height of the virtual scene picture and the first image.

Fig. 6 is a schematic diagram of a second image shown according to some embodiments. As shown in fig. 6, the second image 405 includes an outlining 404.

It is worth noting that the area of the second image other than the outline border may be transparent. Of course, the second image may also comprise only pixels of the outlining.

In step 340, a second image is superimposed on the virtual scene picture.

Here, the second image may be incorporated into the virtual scene screen to be superimposed on the virtual scene screen for display. For example, the outer contour tracing 404 shown in FIG. 6 may be incorporated into the virtual scene picture shown in FIG. 4.

FIG. 7 is a schematic diagram illustrating a display of an outline tracing, according to some embodiments. As shown in fig. 7, an outline border 404 of a virtual object 402 is displayed in a virtual scene screen 401.

Therefore, through the embodiment, the width of the outline tracing is not influenced when the virtual scene is zoomed, and the outline tracing is always consistent, so that the consistency of the tracing effect is ensured. Moreover, since the virtual object is individually rendered to the first image and the outer contour tracing of the virtual object is superimposed on the upper layer of the virtual scene picture, even if the virtual object is blocked in the virtual scene, the complete outer contour tracing of the virtual object can be displayed.

Fig. 8 is a detailed flowchart of step 330 shown in fig. 3. As shown in fig. 8, in some implementations that may be implemented, the following steps may be included.

In step 331, a first pixel point not belonging to the virtual object is determined in the first image based on the color channel to which the virtual object belongs.

Here, in the above-described embodiment, the virtual object is rendered by the solid color into the first image different from the solid color, and therefore, the first pixel point which does not belong to the virtual object can be determined in the first image by the color channel to which the solid color of the virtual object belongs and the color channel to which the background color of the first image belongs.

As shown in fig. 5, the white virtual object 402 and the background color (black) in the first image 403 belong to different color channels, and the first pixel point determined not to belong to the virtual object 402 can be determined in the first image 403 through the color channels.

For each pixel in the first image, whether the pixel belongs to the virtual object or not can be determined according to the color channel to which the pixel belongs, if the color channel of the pixel belongs to the color channel to which the virtual object belongs, the pixel belongs to the virtual object, and if the color channel of the pixel does not belong to the color channel to which the virtual object belongs, the pixel does not belong to the first pixel of the virtual object.

It should be noted that, through the color channel, whether each pixel point of the first image is inside or outside the virtual object can be distinguished in the first image, so as to accurately tracing the outline of the virtual object.

In step 332, for each first pixel, at least one pixel is sampled in the first image within a sampling range centered on the first pixel and having a predetermined stroked width as a radius.

Here, after determining the first pixel points, it may be determined for each first pixel point whether the first pixel point is a second pixel point for which edge tracing is required.

For each determined first pixel point, sampling at least one pixel point in the first image through a sampling range taking the first pixel point as a center and taking a preset tracing width as a radius. The preset tracing width can be set according to actual conditions. For example, the preset stroked width may be 1 pixel, 2 pixels, etc.

Fig. 9 is a schematic diagram of a sampling range shown according to some embodiments. As shown in fig. 9, a sampling range 902 is constructed with a first pixel 901 as a center and a tracing width as a radius, and a plurality of pixels are sampled from a first image through the sampling range 902.

It should be understood that some or all of the pixels within the sampling range are sampled pixels.

In step 333, in the case where the sampled pixel points have pixel points belonging to the virtual object, the first pixel point is determined as the second pixel point.

Here, when at least one pixel belonging to the virtual object exists in the sampled pixel, it is described that the first pixel is an edge point adjacent to the outer contour of the virtual object. At this time, the first pixel point is determined as a second pixel point where the tracing is required.

Fig. 10 is a schematic diagram of a second pixel point shown according to some embodiments. As shown in fig. 10, the gray pixel is the second pixel to be traced.

In step 334, a second image is generated according to the position information of the second pixel, where the pixel corresponding to the second pixel in the second image includes a stroked color.

Here, after all the second pixel points are determined in the first image, based on the position information of the second pixel points in the first image, a second image is generated,

For example, a second image including an outline border of the virtual object may be obtained by coloring, on a transparent image that belongs to the same image space as the first image, a pixel in the transparent image that matches the position information of the second pixel by a preset border color.

In some embodiments, the pixel point corresponding to the second pixel point in the initial image may be colored according to the position information of the second pixel point, and the colored pixel point may be subjected to gaussian blur processing based on a gaussian blur algorithm, so as to obtain the second image.

Wherein the initial image may be an image having a width and a height that are identical to those of the first image. The initial image may refer to a transparent image, for example. After the position information of the second pixel point is obtained, coloring the pixel point corresponding to the second pixel point in the initial image by using a preset tracing color, and performing Gaussian blur processing on the colored pixel point by using a Gaussian blur algorithm.

The gaussian blur algorithm is used to spread the blur effect of the colored pixel points to the side away from the virtual object. The side far from the virtual object refers to an external space outside the outer contour of the virtual object, which does not belong to the virtual object. The Gaussian blur algorithm enables the blur effect to spread to the outside of the virtual object, namely the edge tracing effect can be optimized, and rendering of the virtual object is not affected.

The Gaussian blur algorithm can reduce the jaggy feeling of the outline tracing by diffusing the blurring effect of the colored pixel points to the side far away from the virtual object, so that the outline tracing effect is smoother and more natural.

Therefore, through the embodiment, the virtual object is rendered to the first image, and the outline tracing of the virtual object can be accurately and clearly drawn by distinguishing the pixel points which do not belong to the virtual object, so that the inner outline inside the virtual object is prevented from being drawn.

The following illustrates a description of a method of displaying a tracing edge according to an embodiment of the present disclosure with reference to fig. 11 to 16.

FIG. 11 is a schematic diagram of a virtual scene screen shown according to some embodiments. As shown in fig. 11, in response to a selection operation for a virtual object in a virtual scene, a corresponding virtual scene picture is acquired.

Fig. 12 is a schematic diagram of a first image shown according to some embodiments.

FIG. 14 is a schematic diagram illustrating a display of an outline tracing, according to some embodiments. As shown in fig. 11, 13, and 14, the outer contour outline 1302 shown in fig. 13 is incorporated into the virtual scene screen shown in fig. 11, so that the outer contour outline 1302 corresponding to the virtual object 1202 is displayed in the virtual scene screen.

Fig. 15 is a schematic diagram illustrating gaussian blur effects according to some embodiments.

FIG. 16 is a schematic diagram illustrating a display of an outlining according to further embodiments. As shown in fig. 16, the outer contour tracing after the gaussian blur processing in fig. 15 is combined in the virtual scene picture, so as to reduce the jaggy feel of the outer contour tracing, and make the outer contour tracing effect smoother and more natural.
