Web我想照亮纹理平面，但这不起作用.实体球体上的光很好，但纹理平面不亮. 这是由 OpenGL 标准光模型的 Gouraud Shading 模型引起的问题.虽然 Phong shading 通常意味着技术，它对每个片段进行光计算，在 Gouraud Shading，光计算是按顶点完成的.根据图元上片段的重心坐标对计算出的光进行插值. 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。

WebGouraud shading. Flat shading does not look realistic: Gouraud shading is better. OpenGL uses scan-line interpolationto assign a colour at each point of a projected polygon as a weighted average of given vertex colours.
