WebGouraud Vs Phong Shading Comparison Phong shading more work than Gouraud shading Move lighting calculation to fragment shaders Just set up vectors (l,n,v,h) in vertex shader • Set Vectors (l,n,v,h) • Calculate vertex colors • Read/set fragment color • (Already interpolated) Hardware Interpolates Vertex color a. WebFor Gouraud shading, the Phong lighting calculation is done only at the vertices, and the vertex colors are averaged across triangles. Emissive, ambient, diffuse and specular lighting. These can be toggled off and on independently to allow seeing the different components of the lighting. This is helpful both for educational purposes, and to ...
