WebGouraud shading is considered superior to flat shading and requires significantly less processing than Phong shading, but usually results in a faceted look. In comparison to Phong shading, Gouraud shading's strength and weakness lies in its interpolation. 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。

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. I have a similar problem.

Per-vertex shading involves computation of the shading model at each vertex and associating the result (a color) with that vertex. The colors are then interpolated across the face of the polygon to produce a smooth shading effect. This is also referred to as Gouraud shading. In earlier versions of OpenGL, this per ...
