WebApr 10, 2024 · 2. i would like to make a material that uses gouraud shading instead of phong : That means that the shader is per vertex and not per pixel, i thought i could use … Gouraud shading works as follows: An estimate to the surface normal of each vertex in a polygonal 3D model is either specified for each vertex or found by averaging the surface normals of the polygons that meet at each vertex. Using these estimates, lighting computations based on a reflection model, e.g. the Phong reflection model, are then performed to produce colour intensities at the vertices. For each screen pixel that is covered by the polygonal mesh, colour intensities ca… albatross open https://americanffc.org

The following code. vec3 l = normalize (mat3 (VMatrix)*light); treats light as a direction (by normalizing it and because the translation part of the view matrix is ignored), but it actually is a position. The correct code should be something like.
