单轴分枝乔木分枝处的树皮纹理合成

Bark Texture Synthesis on Branches of Trees With Monopodial Branching

在基本的图割纹理合成方法基础上,提出了拼合曲面上的纹理合成方法,模拟单轴分枝乔木的主干与侧枝、侧枝与侧枝等相交位置的过渡树皮纹理.为了模拟自然生长的单轴分枝乔木分枝处树皮纹理各向异性的效果,将拼接曲面的合成区域划分成子区域,各子区域采用不同的合成方法.实验结果表明:该方法可有效模拟单轴分枝乔木分枝处的树皮纹理,满足真实感绘制的需求.

This paper proposes a flattening surface texture synthesis method based on graphcut texture synthesis method, simulates the transition bark texture of branches of trees with monopodial branching. To simulate the anisotropy effects of the bark texture on branches of natural growth trees with monopodial branching, this paper divides the synthetic region into sub-regions, each sub-region using different synthesis methods. Results show that this method can effectively simulate bark texture on branches of trees with monopodial branching to meet the needs of realistic rendering.
