Web着色模型：高洛德着色(Gouraud shading)：即基于顶点计算颜色后在渲染的图元内部进行线性插值。当光照模型中有非线性的计算时（如计算高光反射），这种逐顶点的光照就会出问题。另外由于是图元内部线性插值，会导致渲染图元内部的颜色总是暗于顶点处，在某些情况下会产生明显的棱角现象。 WebOpenGL Shading Language code sample[edit] This sample in the OpenGL Shading Languageconsists of two code files, or shaders. The first one is a so-called vertex shaderand implements Phong shading, which is used to interpolate the surface normal between vertices.

Web12 de jul. de 2001 · Gouraud shading falls down if the polygon is very large and a light patch should appear in the center. This is because only lighting at the vertices is calculated. Phong shading is the next step up, but takes a lot longer to calculate. If you get this problem, subdivide your polygons.
