WebImplementing flat shading. 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 ...

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。 Web22 de abr. de 2024 · At Gouraud Shading the light calculations are done in the vertex shader, for the corners of the primitives (corners of the triangles).

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.
