The above three-dimensional object refers to a three-dimensional virtual object existing in a three-dimensional virtual environment. For example, the three-dimensional object may be a three-dimensional object or a three-dimensional character.

Step 202 , detecting touch points in the interactive interface, the initial number of touch points is 2, and the current number of touch points is 1 or 2.

In the embodiment of the present application, the computer device can detect the touch operation of the user in the interactive interface in real time, wherein the initial number of touch points corresponding to the touch operation is 2, that is, when the three-dimensional object is rotated , the user first performs a touch operation on the touch screen by means of two-point touch.

Step 203, when the touch point in the interactive interface moves, rotate the target 3D object in at least one 3D object; the rotation angle of the target 3D object is related to the movement of the touch point, and the rotation axis of the target 3D object is Relative to the current number of touch points.

Please refer to FIG. 3 , which shows a flowchart of a three-dimensional object rotation method provided by an exemplary embodiment of the present application. The method may be performed by a computer device; wherein, the first computer device may be the computer device 10 shown in FIG. 1 above. The method may include the following steps.

In step 301, an interactive interface is displayed, and at least one three-dimensional object is displayed in the interactive interface.

In this embodiment of the present application, the computer device may display an interactive interface, and may display at least one three-dimensional object in the interactive interface.

The interactive interface may be a two-dimensional view interface, and the two-dimensional view interface may be an interactive interface displayed on a two-dimensional view screen. The computer device may display an interactive interface on a two-dimensional view screen and display at least one three-dimensional object on the two-dimensional view interface.

In a possible implementation manner, the computer device may be a terminal device, and the terminal device may be a smart phone.

For example, please refer to FIG. 4 , which shows a schematic diagram of an interactive interface involved in an embodiment of the present application. As shown in FIG. 4 , the computer device (smart phone) displays a UI interface, and the UI interface can be the above-mentioned interactive interface, and a virtual world 40 (virtual world) and at least one three-dimensional object 41 (3D object) are displayed on the interactive interface, The UI interface can be displayed on a display screen, and the display screen can be a multi-touch screen 42. The multi-touch screen 42 can support the computer device to receive multi-point excitation signal instructions during multi-touch. The user can view the virtual world 40 and the three-dimensional objects 41 therein through the UI interface.

Step 302 , detecting touch points in the interactive interface, the initial number of touch points is 2, and the current number of touch points is 1 or 2.

In the embodiment of the present application, the computer device can detect the touch points in the interactive interface. Since the initial number of touch points in the interactive interface is 2, the current number of touch points in the currently detected interactive interface can be determined, The current number of detected touch points can be divided into two cases, one is to maintain the initial number, that is, the current number of detected touch points is still 2, and the other is to reduce the number of touch points, that is, the detected The current number of touch points is 1.

In a possible implementation manner, the computer device periodically detects the touch points in the interactive interface, or the computer device detects the touch points in the interactive interface in real time.

That is to say, when the computer device displays the interactive interface, and the interactive interface includes at least one three-dimensional object that supports rotation, the computer device can periodically or in real time detect whether there is a touch point in the interactive interface and determine whether the touch point exists. Current quantity.

Since the computer device displays the interactive interface through the multi-touch screen, the computer device can detect multiple touch points acting on the multi-touch screen.

Step 303: Determine the rotation axis of the target three-dimensional object according to the current number of touch points.

In this embodiment of the present application, the computer device may determine the current rotation axis for the target three-dimensional object according to the current number of detected touch points.

The target three-dimensional object may be one of at least one three-dimensional object displayed on the interactive interface, and the target three-dimensional object may be a three-dimensional object that currently supports rotation.

In a possible implementation manner, when a three-dimensional object is displayed on the interactive interface, the computer device can directly determine the three-dimensional object as the target three-dimensional object, and the computer device can automatically lock the target three-dimensional object in the three-dimensional objects. When at least two three-dimensional objects are displayed on the interactive interface, the computer device may randomly select one of the at least two three-dimensional objects as the target three-dimensional object, or may select one of the at least two three-dimensional objects according to the currently detected position of the touch point. Select one of the objects as the target 3D object.

Wherein, in the case where the number of at least one three-dimensional object is n, and n is an integer greater than or equal to 2, when the current number of touch points is 2, and a continuous touch occurs at one of the two touch points Click to switch the target 3D object among the n 3D objects.

That is to say, if there are at least two three-dimensional objects currently in the interactive interface, and the computer device detects that there are at least two touch points, it can be determined according to the positions of the detected two touch points. The target 3D object, when the computer device receives a continuous click operation at any one of the at least two touch points, it switches the current target 3D object, that is, one of the remaining 3D objects can be replaced with the target three-dimensional objects.

Exemplarily, the current target 3D object may be displayed in the central area of the interactive interface, the current remaining 3D objects may be displayed in the edge area of the interactive interface, and the displayed size of the target 3D object in the central area may be larger than that in the edge area. The current remaining 3D object. When the computer device detects that the current number of touch points is 2, and receives a continuous click operation at the position of any one of the two touch points, one of the three-dimensional objects in the edge area can be Display in the center area, and display the 3D object previously in the center area in the edge area, so that the current target 3D object can be switched. If the currently switched target 3D object still needs to be replaced, it will continue to receive 2 touch points. A continuous click operation occurs at the position of any one of the touch points, until the three-dimensional object displayed in the central area is the final target three-dimensional object.

In addition, when the computer device detects that the current number of touch points is 2, and a continuous click operation occurs at the position where any one of the two touch points is received, it can be prioritized to determine the touch for which the continuous click operation occurs. Whether there is a 3D object in the direction of the point, if there is a 3D object in this direction, the 3D object in the edge area of the direction and the 3D object in the center area are preferentially switched. Through the above convenient operations, the steps of quickly switching the target three-dimensional object in the interactive interface can be realized, which greatly improves the efficiency of determining the target three-dimensional object, and at the same time, no additional touch operation is required, and the operation convenience is improved.

In a possible implementation manner, when the computer device detects that the current number of touch points is the initial number, that is, two touch points, it can be determined that the current rotation axis for the target three-dimensional object may be perpendicular to the screen axis of rotation. When the computer device detects that the current number of touch points becomes one touch point, it may be determined that the current rotation axis for the target three-dimensional object may be a rotation axis parallel to the screen.

Wherein, when the current number of detected touch points is 2, the computer device may determine that the rotation axis of the target three-dimensional object may be perpendicular to the screen, and the rotation axis may pass through the center of mass of the target three-dimensional object or the rotation axis may pass through the current The midpoint of the line between the two detected touch points. When the current number of detected touch points changes to 1, the computer device may re-determine the current rotation axis for the target three-dimensional object, the re-determined rotation axis may be a rotation axis parallel to the screen, and the rotation axis may be The mid-perpendicular line of the target connection line may also be an axis perpendicular to the target connection line and passing through the centroid of the target 3D object. The target connection line may be a connection line between the two touch points at the moment before one of the two touch points disappears.

Step 304, when the touch point moves, control the target three-dimensional object to rotate according to the rotation axis.

In this embodiment of the present application, when the touch point moves, the computer device may control the target three-dimensional object to rotate according to the rotation axis determined above.

The current rotation axis for the target 3D object is determined according to the current number of touch points detected by the computer device, and when the touch point moves, the target 3D object can be controlled to rotate according to the determined rotation axis.

In a possible implementation manner, when the touch point moves and the current number of touch points is 2, the control target three-dimensional object is rotated according to a rotation axis perpendicular to the screen.

That is to say, when the current number of trigger points is 2, it can be determined that the rotation axis is perpendicular to the axis of the screen, and when one or both of the two touch points move, the computer device can control the target 3D object according to the determined rotates the axis of rotation.

Wherein, the rotation angle of the target three-dimensional object may be positively correlated with the rotation angle of the line connecting the two touch points.

That is to say, the rotation angle of the target 3D object may be the rotation angle of the line connecting the two touch points, or the rotation angle of the target 3D object may be the rotation angle of the line connecting the two touch points and a fixed ratio. That is, the computer device can process the rotation angle of the line connecting the two touch points according to a fixed ratio to obtain the rotation angle of the target three-dimensional object.

Alternatively, the above-mentioned ratio may be a dynamically changing ratio, and the numerical value of the ratio may be related to the rotation speed of the connecting line of the two touch points for rotation, that is, the rotation speed of the line connecting the two touch points is higher. , the value of the corresponding ratio is relatively large at this time, and when the rotation speed of the connecting line between the two touch points is relatively small, the value of the corresponding ratio is relatively small at this time, because determining the rotation angle of the target 3D object combines the touch Considering the factor of the rotation speed of the connection line of the control points, it is convenient for the user to realize the rotation operation of the target three-dimensional object in a relatively fine manner by reducing the rotation speed.

For example, FIG. 5 is a schematic diagram of determining a rotation angle involved in an embodiment of the present application. As shown in Figure 5, A and B are the current two touch points respectively, A' is the touch point after A's movement, and B' is the touch point after B's movement. In the first case 51a, the rotation The angle may be the angle of the acute angle AOA'; in the second case 51b, the rotation angle may be the angle of the obtuse angle AOA'; in the third case 51c, the rotation angle may be the difference between 360 degrees and the angle of the acute angle AOA'; In the fourth case 51d, the rotation angle may be the difference between 360 degrees and the obtuse angle AOA'.

Exemplarily, FIG. 6 is a flowchart of a two-finger operation involved in an embodiment of the present application. As shown in Figure 6, if the target 3D object needs to be rotated 90 degrees around the z-axis perpendicular to the screen, it is recommended that the user perform the manipulation gesture to rotate around the axis perpendicular to the screen, and the user places two fingers on the screen. , forming a touch point on the screen (S61), at this time it can be determined that the rotation axis passes through the center of the line between the touch points of the two fingers, and the rotation axis is also perpendicular to the line between the two fingers ( S62), by rotating the two fingers clockwise or counterclockwise (S63), the rotation angle of the target three-dimensional object around the z-axis can be changed, and when the rotation angle reaches the expected 90 degrees, that is, after the rotation angle is sufficient, it can stop The rotation of the two fingers is performed, and the contact between the two fingers and the screen is released (S64), and the rotation of the target three-dimensional object is completed this time. FIG. 7 is a schematic diagram of displaying a two-finger operation screen according to an embodiment of the present application. As shown in FIG. 7 , in the first interactive interface 71, the touch points of the two fingers for the target three-dimensional object are determined, and in the second interactive interface 72, the two fingers are controlled to move clockwise around the z-axis. Rotate and move, you can control the target 3D object to rotate clockwise around the z-axis. In the third interactive interface 73, when the target 3D object rotates to 90 degrees, you can release two fingers to end the two-finger control of the target 3D object. Rotation operation.

In another possible implementation manner, when the touch point moves and the current number of touch points is 1, the control target three-dimensional object rotates according to the rotation axis parallel to the screen and perpendicular to the target connection line. The target connection line may be a connection line between the two touch points at the moment before one of the two touch points disappears. The rotation angle of the target three-dimensional object may be positively correlated with the moving distance of the touch point in the current screen.

The rotation angle of the target three-dimensional object may be the product of the ratio between the distance of the current touch point moving in the direction of the disappearing touch point and the distance of the target connection line and 180 degrees. Alternatively, the rotation angle of the target three-dimensional object may also be the product of 360 degrees or 270 degrees multiplied by the ratio between the distance of the current touch point moving in the direction of the disappearing touch point and the distance of the target connection line.

In a possible situation, if the current touch point moves in the direction of the disappearing touch point and exceeds the range of the target connection, the rotation angle can be determined to be 0 degrees; or, if the current touch point moves in the direction of the disappearing touch point If the touch point moves in the opposite direction and exceeds the original position of the current touch point, it can be determined that the rotation angle is 0 degrees.

For example, FIG. 8 is a schematic diagram of determining a rotation angle involved in an embodiment of the present application. As shown in FIG. 8, in the first case 81a, if point A is the touch point that has disappeared, point B is the current touch point, B' is the current touch point after moving, and the target three-dimensional object The calculation formula of the rotation angle can be as follows,

In the second case 81b, since B' moves in the direction of A and exceeds the range of BA, the rotation angle at this time is 0 degrees. In the third case 81c, since B' moves toward B and exceeds the range AB, the rotation angle at this time is 0 degrees.

Exemplarily, FIG. 9 is a flowchart of a single-finger operation involved in the embodiment of the present application. As shown in Figure 9, if the target 3D object needs to be rotated by a certain angle around the axis of rotation parallel to the screen, it is recommended that the user perform the manipulation gesture to rotate around the axis parallel to the screen, and the user places two fingers on the screen. , forming touch points on the screen (S91), at this time, it can be determined that the rotation axis passes through the center of the line between the touch points of the two fingers, and the rotation axis is also perpendicular to the line between the two fingers (S92), then release one of the fingers, that is, leave the screen, and move the finger still in contact with the screen toward the direction of the other finger (S93), the target three-dimensional object can be changed around the rotation axis parallel to the screen The rotation angle of the rotation, when the rotation angle reaches the expected angle, that is, after the rotation angle is sufficient, the movement of the finger can be stopped, and the contact between the finger and the screen can be released (S94) to complete the rotation of the target three-dimensional object. FIG. 10 is a schematic diagram of displaying a single-finger operation screen according to an embodiment of the present application. As shown in FIG. 10 , in the first interactive interface 1001, the touch points of the two fingers for the target three-dimensional object are determined, and in the second interactive interface 1002, one of the fingers is released to make it leave the screen , move the other finger in the direction of the upper finger, determine the rotation axis at this time as the mid-perpendicular line connecting the two fingers before releasing the finger, and control the direction of the target 3D object by controlling the upward movement distance of a single finger. Rotation angle, in the third interactive interface 1003, when the target three-dimensional object rotates to 90 degrees, the finger can be released to end the operation of controlling the target three-dimensional object to rotate with one finger.

In a possible implementation manner, since the initial number of touch points is 2, first the computer device performs a two-finger operation, and controls the target three-dimensional object to rotate according to the rotation axis perpendicular to the screen through the two-finger operation, and then when the When the rotation angle in the direction meets the requirements, control the target 3D object to rotate according to the rotation axis parallel to the screen through a single-finger operation until the rotation angle in the direction meets the requirements. If you still need to continue to adjust the rotation perpendicular to the screen If the rotation angle of the axis is rotated, it can be turned into a two-finger operation again to control the rotation angle of the target 3D object.

Exemplarily, FIG. 11 is a flow chart of rotation control of a target three-dimensional object involved in an embodiment of the present application. As shown in FIG. 11 , first, the computer device can display the virtual world on the screen, and display the three-dimensional object in the virtual world, and the user can view the three-dimensional object (S1101). When one of the three-dimensional objects is selected as the target three-dimensional object, it can realize The focusing operation on the three-dimensional object (S1102) determines whether the user needs to view the target three-dimensional object in another direction (S1103). The gesture of rotating the axis of the screen, first perform the two-finger operation (S1104), and then recommend the user to use the gesture of rotating around the axis perpendicular to the screen, and then perform the single-finger operation (S1105). When adjusting the viewing direction of the target three-dimensional object meets the requirements , you can end the operation. By combining the above two-finger operation and single-finger operation, the target three-dimensional object can be rotated to any direction.

To sum up, in the solution shown in the embodiments of the present application, when the user rotates the target three-dimensional object by sliding touch on the touch screen, the user can select the rotation axis by single-point/two-point touch, and touch and slide The rotation angle is controlled by the situation, so that the method of simultaneously selecting the rotation axis and controlling the rotation angle through the touch of two fingers is realized, which simplifies the operation steps when the user rotates the three-dimensional object through the touch screen, shortens the user's operation time, and improves the Human-computer interaction efficiency when rotating 3D objects in a touchscreen.
