| 摘 要： | 在层状纹理切片表达真实感短毛发的GPU实现方法中,模型轮廓处毛发切片的计算与生成需要消耗很大的显存,影响绘制效率。通过几何着色器进行边缘检测和生成Fin,改善轮廓处毛发切片渲染效率,则不必为边缘检测在每条边都加入退化三角形到网格。与此前方法相比,显存几乎没有消耗,提高了绘制效率。

| Abstract: | In the implementation methods that represent furry surfaces with multi-layer textured slices,the computation and generation of silhouette fur always deplete much video memory,greatly affecting rendering efficiency.By using geometry shaders,image edge is detected and Fin is generated,which improves the rendering efficiency,making it unnecessary to add degenerated triangular to the grids on each edge for the sake of edge detection.Compared with the previous method,little video memory is depleted and rendering efficiency is improved. |
