Appearance of a triangle strip. Surface normals? Or windings?
一个三角形条带的外观。表面法线？或绕组？
For example, I would subdivide all the meshes a couple of times to check for any holes, sculpt on them a little to check for proper surface normals, etc.
我细分下所有模型几次检查是否有洞；在模型上雕刻几下检查表面法线是否正确等等。
Interpolation to vertex positions and normals is one of important contents in parametric surface modeling.
顶点位置和法向插值是参数曲面造型的重要内容。
We subdivide very single planar triangle independently, and finally get a smooth surface interpolating the vertices of the original triangle mesh and their normals.
通过对单个平面三角片的单独细分，最后我们得到一张插值原三角网格顶点和顶点法向的光滑曲面。
These bumps would only be apparent due tothe way lighting appears on the surface, because these modified normals areused in the lighting calculations.
但在面与面的交界处，由于其法线需要重新计算，这就形成了明显的阴影过渡的痕迹。
