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. Web11 de mai. de 2016 · Fixed-function OpenGL provides only two local lighting models which actually attempt to simulate real-world lighting: flat shading, which produces values for a whole primitive and Gouraud shading which produces values at vertices which are then interpolated across the primitive.
