2) Texture color replacement: the diatom ooze pattern is a new finished function, so that the old material cannot be well supported, the texture of the old material is required to be filtered, the color replacement logic is used, whether the material can be subjected to color replacement or not is judged according to the special field of the material, if the material cannot be replaced, the filtering is carried out, and the subsequent flow is not carried out;
3) Color replacement: color replacement is carried out on the pattern and the texture, the color replacement of the non-transparent area is carried out on the pattern and the texture based on Opencv, and the color of the pattern is replaced: traversing the pattern pixels, and if the pattern pixels are non-transparent areas, replacing the pixel colors with colors selected by users; texture color replacement: two pictures exist in texture, 1 pure color picture, 1 concave-convex mapping representing texture, the pure color picture is regenerated, and 1 pure color picture with the color selected by a user is generated for replacement;
4) And (3) calculating mixed materials: combining the generated picture with the original material attribute, and generating a mixed material;
for example, in fig. 1, we need to combine the generated picture with the original texture attribute to generate the mixed texture. Based on the characteristics of the pattern overlay, we need to generate 2 parts of the blended material in total, as shown in fig. 4. Brown deer as a mixed material: 1. brown deer material comprising patterns and concave-convex stickers; 2. the diatom ooze texture material comprises texture maps and concave-convex maps; 3. the mixed material comprises mixed amount and a real-time baking chart. Mixing white feather and intersected brown deer parts: 1. the brown deer material of the bottom layer comprises patterns and concave-convex stickers; 2. the upper layer of white feather material comprises patterns and concave-convex stickers; 3. the diatom ooze texture material comprises texture maps and concave-convex maps; 4. the mixed material comprises 2 mixed amounts and 1 real-time baking chart;
5) Multi-pattern superposition: stacking sub-materials according to the priority;
for example: two mixed materials are adopted, wherein white feathers and intersected brown deer which are mixed materials are multiple sub-materials, and logic superposition is needed. The sub-materials are ordered according to the pattern sequence uploaded by the user. The effect of white feathers was determined to be produced on top of brown deer.
6) And (3) synthesizing mixed materials: assembling the obtained basic materials and sub-materials according to the mixed material format of FIG. 1 to obtain a final mixed material;
7) Rendering materials: submitting the constructed model and the mixed material to rendering; from 5.7 we obtained two blends. We perform reconstruction of the model as shown in fig. 9. In fig. 9, we can clearly see the 2 areas of material, the brown deer and white feather of the mixed material are respectively placed in the two areas, and the maximum area of the background is placed with the material with the texture of diatom ooze. And submitting the constructed model and the mixed material of 5.7 to rendering together, so as to finish the effect presentation of the figure 4.
8) And (5) performing high-order design.
The algorithm for filtering the effective cutting area is as follows: defining an effective area as a closed area formed by a plurality of curves, wherein a straight line is used as a special curve, namely after orderly discretizing all the curves, judging whether all the line segments are connected first or not, and forming the closed area.
The pattern cutting comprises an algorithm supporting transparent pattern cutting, which mainly comprises the following steps: generating a picture, wherein the size of the picture is the same as that of the pattern, the drawing cutting area is filled in black, and the other parts are filled in white, namely, the cutting area mask; and merging the patterns through the mask of the cutting area by using a bitwise_and function of opencv to obtain the cutting patterns filtered by the mask area.
The high-order design mainly comprises pattern cutting, multi-pattern superposition, pattern color replacement, diatom ooze texture color changing and size adjustment. Specifically, each higher-order design process is:
1) Cutting patterns: the user can manually draw the outline on the tool side for pattern splitting, as shown in fig. 10.
By recording the effective area drawn by the user, we enter the generation of the blended material by: effective area screening- > cutting outline of pattern- > calculating mixed material by using cut pattern- > generating final mixed material- > submitting material to rendering middle stage, and obtaining effect. The final effect is shown in figure 11.
2) Multi-pattern superposition: the user can adjust the position of the pattern on the tool side, and multiple patterns are superimposed together to obtain a mixed effect, as shown in fig. 12.
By recording the sequence of patterns placed by a user, the mixing quantity priority of the mixed materials is adjusted, and the flow is as follows: the method comprises the steps of calculating mixed materials, overlapping sub-materials according to priority, obtaining a base material which is a fan-shaped texture, generating a final mixed material by using a plurality of mixed materials with patterns which are sub-materials, and submitting the materials to a rendering center to obtain an effect graph. The final effect is shown in fig. 13.
3) Pattern color substitution: the user can modify the color of the pattern on the tool side, and can modify the pattern to the favorite color in real time, as shown in fig. 14.
Through carrying out color replacement to the pattern that the user uploaded, we can see different color effects very conveniently, and the flow is as follows: performing calculation of mixed materials, performing color replacement processing on sub-materials, generating final mixed materials, and submitting the materials to a rendering center to obtain an effect diagram. The final effect is shown in fig. 15.
4) And (3) changing the texture and color of the diatom ooze and adjusting the size of the diatom ooze: the user can modify the texture, color and size of the diatom ooze on the tool side, can modify the diatom ooze into favorite colors and sizes in real time, and can see the effect in real time, as shown in fig. 16.
Through carrying out color replacement and material scale (picture scaling) modification to diatom ooze texture map that the user uploaded, we can very convenient see different colors, size effect, and the flow is as follows: effective texture screening- > calculation of mixed materials- > replacement processing of colors on basic materials- > calculation of new scale on basic materials- > generation of mixed materials- > submitting the materials to a rendering center to obtain an effect diagram. The final effect is shown in figure 17.
The mixed material of the invention is used as one of the cores of diatom ooze pattern design, and the core concept is shown in figure 1. The multi-material superposition effect is mainly realized, and the realization effect is shown in figure 2. Based on the above concept, the texture material and the pattern material are recombined into new mixed materials based on the image processing energy level, which is the core of the present invention, as shown in fig. 3. The underlying picture processing capability is mainly implemented by opencv.
The main flow of the method is shown in figure 1. The core is divided into three parts of picture generation, material synthesis and model reconstruction. Based on the present design, there are a number of implementation methods to achieve the effect of fig. 4. The core is the generation of the material picture based on the figure 1, the material generation and the final presentation of the effect to the model.
1) And (3) generating a picture: and defining a data structure of the diatom ooze pattern and the texture, and calculating to obtain an offset relation between the pattern and the texture through corresponding data. As in the scene of fig. 4, there are a total of 3 materials, and the 3 materials require perfect alignment of textures in the texture color replacement scene. The offset, rotation and scaling relation of the pattern relative to the texture and texture are needed to be calculated. And calculates it onto the picture composition. If the pattern has the requirements of replacing colors and partially editing, the corresponding data is reflected on the picture of the pattern material. Besides, the capability of real-time effect presentation is realized through the baking map, the material effect is simulated through the capability of rendering and baking by the picture editing, and the user experience is greatly improved. And finally, transmitting the generated material to a material synthesis module.
2) And (3) material synthesis: the main process in the material synthesis is to generate pictures and sort the properties of partial parameterized materials; as shown in the scene of FIG. 4, we need to redefine the properties of material such as scaling, and combine the generated pictures into the material to generate multiple mixed materials.
3) Model reconstruction: the model reconstruction mainly comprises mixed materials and region division. As in the scenario of fig. 4. We need to divide a model into 3 areas, and the 3 areas are respectively placed with brown deer mixed material, white feather mixed material and diatom ooze texture material. And (3) corresponding the material to the region, and carrying out corresponding assignment on the region and the material attribute of the model, so as to ensure that the texture of the 3-point material is completely aligned. Achieving the perfect alignment effect of the effect.
It should be understood that equivalents and modifications to the technical scheme and the inventive concept of the present invention should fall within the scope of the claims appended hereto.
