Description

A Method of Arranging Three-Dimensional Graphics

technical field

The invention belongs to the technical field of image and graphics processing, and in particular relates to a method for arranging three-dimensional graphics.

Background technique

At present, in the fields of graphic design, advertisement production, etc., in the process of three-dimensional graphics production and processing, it is often necessary to arrange a large number of identical graphics in a certain order, for example, in the production of calendars, wall tiles, classified advertisements, etc. When waiting for graphics, there is a situation where a huge number of graphics needs to be arranged regularly. To achieve this effect, the general approach currently adopted is as follows:

(1) Make a smaller graphic as the original material;

(2) copy multiple such graphics;

(3) Arrange these graphics according to the rules according to the needs, and the method of arrangement mostly adopts "alignment", "equal distance" and other methods.

There are two main defects in the above-mentioned method: (1) the workload of duplicating graphics is relatively large. When the quantity of graphics is large, directly duplicating these graphics is a troublesome work, and the quantity of duplication is difficult to control, especially if the quantity is large. When there are more than 200, this deficiency will be more obvious; (2) After copying, it is also difficult to arrange these graphics. In an advanced image editing and design software, there are many graphics effects, and the graphics are located in different layers. After arrangement, both the position and the graphics effect must be correct. This operation is undoubtedly a cumbersome and difficult task to do manually.

It can be seen that the existing methods for copying and arranging graphics have faced many difficulties when the quantity is large. As mentioned above, copying a large number of identical 3D graphics will inevitably make the operating environment very confusing, especially in the case of a particularly large number of graphics. Sometimes, for example, there are hundreds of the same graphics, it is difficult for the operator to accurately select the required graphics. Moreover, the arrangement of these graphics is generally done roughly first, and then aligned by top, bottom, left, right, center alignment, etc., and then Use the equidistant method to adjust the distance between graphics. This is a method of repeated adjustments and gradual accuracy. There must be no mistakes in the adjustment process, and any mistakes will greatly prolong the working time. Obviously, this job has high requirements on personnel and is an error-prone job.

Contents of the invention

For the defects existing in the prior art, the purpose of the present invention is to provide a method for three-dimensional graphic arrangement, which only needs to make an original large graphic, and then scale it to a target graphic as required, and copy the target graphic as The required quantity, each target graphic has all the attributes of the original graphic except the size of the graphic, and the arrangement relationship of the target graphic is adjusted according to certain rules. When copying and arranging a large number of graphics, it can realize one-time production, rapid generation, and automatic adjustment. Effect.

4) Obtain the frame coordinates of any two target graphics, that is, the position of the graphics, and sort the graphics according to the rules established in step 3);

5) traverse all the graphics to form an ordered sequence of graphics;

6) Arrangement ends.

Further, step (2) may be realized by the following method: after setting the position and range of the target area, determine the number n of graphics to be copied according to the size and spacing of the target graphics.

Furthermore, when setting the spacing of the graphics in step (2), the horizontal spacing and the vertical spacing are the same.

Further, the characteristics of the target figure in step (4) include the positional relationship, rotation angle, and figure direction of the target figure.

Furthermore, when adjusting the hierarchical relationship of graphics in step (4), all target graphics are placed on the same layer according to the arranged order.

In addition, when adjusting the hierarchical relationship of graphics in step (4), translation transformation is also performed on the target graphics according to the rotation angle.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the present invention will be further described:

As shown in Figure 1, a method for arranging three-dimensional figures comprises the following steps:

(1) Make a three-dimensional original graphic 1; the original graphic is a graphic produced by any tool; if the original graphic already exists, it is directly read.

In this embodiment, the graph shown in FIG. 3 is a schematic diagram of the original graph, the coordinate system and the graph rotation angle α, where α=15°. Fig. 4 is an actual effect diagram of arranging three-dimensional graphics by using the existing method. The black arrow indicates the direction of the graphics, and there is no offset of the target graphics. It can be seen that the levels of the graphics in Figure 4 are rather chaotic, and the arrangement affects the correct effect.

(2) According to requirements, set the position and range of the target area A×B; when setting the number of target graphics n, you need to calculate n=W×H, n is the total number, W is the number of horizontal, H is the vertical Quantity; where n, W, and H are all positive integers; when setting the spacing of graphics, it is necessary to set the horizontal spacing G ₁ and the vertical spacing G ₂ of adjacent graphics; vice versa, it can also be based on the size and spacing of the target graphics Calculate the range of the target area to determine the number of graphics that need to be copied.

In this embodiment, the target area is 100mm × 80mm; the target quantity is 5 × 4 and there are 20 in total; the horizontal spacing and vertical spacing of adjacent graphics are respectively 5mm and 4mm; the origin of the target area is (0,0 among Fig. 3 )point.

(3) Scale the original graphics, and calculate the size of the target graphics according to (A-(W-1)×G ₁ ) and (A-(H-1)×G ₂ ).

In this embodiment, the width (100-4*5)÷5=16mm of the target pattern, and the height (80-3*4)÷4=17mm. Generate a target figure of 16×17mm, then copy 19 target figures, and place 20 figures in the target area.

Since the copying process is completed in the same layout, the target graphics are in the same coordinate system. At the same time, the method of copying makes all the target graphics have the same size, rotation angle (α) and graphics direction (black arrow in Figure 4).

(4) Collect all the target graphics, formulate sorting rules according to the characteristics of the target graphics, sort the target graphics, complete the arrangement, and then adjust the hierarchical relationship of the graphics. The target graphic features include the positional relationship, rotation angle, and graphic direction of the target graphic.

As shown in Figure 2, in this embodiment, when the target graphics are sorted, the method of comparing the positional relationship of the target graphics is adopted, and the method includes the following steps:

1) As mentioned above, all target graphics are already in the same coordinate system. In this embodiment, 20 target graphics are located in the orthogonal coordinate system U, V. Set the priority 8 of the coordinate system. In this embodiment, the vertical V coordinate system is the main one, and the horizontal U coordinate system is secondary, that is, the priority of the vertical V coordinate system is higher than that of the horizontal U coordinate system;

2) Obtain the position, rotation angle, and direction of the target graphic;

3) According to the information in step 2), a unified sorting rule 9 is formulated to facilitate the comparison of the positions of the target graphics. The key to sorting is to compare the positional relationship. The core idea is that one direction is the main direction and the other direction is the second, so as to determine the priority of sorting. As mentioned in step 1), the vertical V coordinate system is the main one, and the horizontal U coordinate system is secondary. In the process of comparing the positional relationship, if the vertical coordinates V are not the same, only the vertical coordinates are compared, and the horizontal coordinate U is not considered; if the vertical coordinates are the same, the horizontal coordinates are considered again.

4) Obtain the frame coordinates of any two target graphics, that is, the positions of the graphics, and sort the graphics according to the rules established in step 3), such as 10, 11, and 12 in FIG. 2 .

In this embodiment, as shown in Figure 5, there are three figures a, b, and c, and a is on the left side of b. According to the comparison rules formulated in this embodiment, compare the same positions of a and b, such as comparing a and On the left side of b, a<b, so a is in front of b in the sequence; similarly, b is at the bottom right of c, since the priority of coordinates has been determined before, the vertical priority is high, compare b and c The top side, b<c, b is in front of c, so far, a local ordered queue "abc" is formed, and the arrangement of other target graphics can be deduced by analogy.

5) Traverse all target graphics until all target graphics form an ordered queue, as shown in Figure 613.

(5) Put all the graphics on the same layer in turn according to the arranged order, the effect is shown in Figure 7. In some cases, it may be necessary for the graphics and the original graphics to be consistent in basic form, and the target graphics can be transformed according to the rotation angle to form Figure 8.

Embodiment 2: other steps are identical with embodiment 1, and difference is: when setting the spacing of adjacent target figure in step (2), lateral spacing G ₁ and vertical spacing G ₂ are identical, all being 5mm. In step (3), the width (100-4*5)÷5=16mm of the target figure, and the height (80-3*5)÷4=16.25mm.

The above description is just a simple example of the present invention, and the present invention is not limited by this example. All slight changes, modifications or deletions of intermediate steps according to the idea of the present invention and the aforementioned variations are within the scope of rights of the present invention.
