Embodiment Construction

[0049]Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] figure 1 A schematic block diagram of an embodiment of the present invention is shown. Such as figure 1 As shown, the three-dimensional surface texture synthesis method based on the distribution of primitives includes the following steps:

[0051] Step 1: Extract Primitives

[0052] Initially, the user only marks the sample texture image (as attached figure 2 As shown in ), one or two primitives with prominent colors and complete shapes are used as the foreground, and the background area that is relatively close to the foreground position and has a significant color difference is also marked as the background, so that marking the front and background areas can effectively avoid the foreground and background colors. Similar timing results in suboptimal segmentation. In addition, since there are many primitives in the sample texture image and t...

Abstract

The invention relates to a three-dimensional surface texture synthesis method based on primitive element distribution. The method comprises the following steps: extracting a primitive element; constructing a primitive element connecting relation; generating a three-dimensional model surface vector field; constructing three-dimensional model surface primitive element distribution; and disposing the primitive element on the surface of the three-dimensional model. According to the invention, effectively texture mapping can be realized under the condition of local parameterization of the three-dimensional model, and a lot of neighborhood matching search of sample texture during the synthesis process is avoided. Thus, high-efficiency texture synthesis can be carried out on the three-dimensional surface. In addition, completeness of the primitive element and continuity and regularity of the texture structure in the synthesis result can be effectively maintained, and then a high-quality three-dimensional surface texture synthesis result is obtained.

Description

technical field [0001] The invention relates to a three-dimensional surface texture synthesis method, in particular to a three-dimensional surface texture synthesis method based on primitive distribution. Background technique [0002] In computer graphics, 3D surface texture synthesis is to directly generate a texture pattern similar to the sample texture on a 3D surface. Its main function is to add surface details to the 3D model, thereby enhancing the realism of the model surface. This can not only make up for the lack of geometric drawing, but also greatly simplify the modeling process. There are a large number of repeated texture elements in the texture, and the repeated texture elements are texture primitives. [0003] At present, one of the most direct ways of texture synthesis on a 3D surface is: first, a texture image with a large enough size needs to be obtained, that is, a texture image with any size and similar to the sample texture is automatically generated by ...
