Some meshes show smoothing in gouraud


#1

hi all,

I extruded some illustrator paths, but some meshes show some kind of smoothing. I had a look at the 3d file and it looks fine to me.

Any ideas what this could be related to?

if you want to have flat normals you need to generate surface normals, not per vertex normals. normals get interpolated by the rasterizer and depending on the curvature of the object that is more or less visible.
