When I create a sphere (or any shape) I can see each facet. How do I get the smooth sphere effect. Is it that I am using a single normal for each quad? I tried both smooth and flat shading and I see no difference.
you need to provide a normal for each vertex, average the normals of each face that a vertex is in to find the normal of that vertex
Isnt there a shading method that uses the angles of 2 tris and if its less than a number (so you keep sharp corners) it makes a new normal. or something like that???
if you are doing a sphere, the normal should be the same as the vertex, because all of the points in a sphere are the same distance away from the center. yeah, i didn’t explain that well, but it works.
