Wood Solid Texturing Based on Specimens
基于样图的木材体纹理绘制方法

The color of solid texture space is defined traditionally through a function model.To simulate different texture details,the relevant parameters need to be modified and tested repeatedly,however good results could rarely be acquired.A new method of solid texturing based on specimens is proposed in the paper.We establish geometrical mappings between the specimen space and solid texture space according to the structure characteristic of wood texture,and define the color of solid texture space using the texture value of specimen pixels.The results from our experiments show that the wood texture produced by this method successfully represents realistic texture details on the specimens and is continuous between the conterminous surfaces of objects.As the wood specimens may be selected according to user's requirements,solid texturing based on specimens is a superior technique which could evidently promote the quality and the variety of wood texturing.
