I’m rendering a surface composed of quads (i havn’t been able to get triangle_strips to work properly) from
an array like this,
float surfacedata[xsize][ysize];
I’m suspicious of using quads, since I’m worried
they might contain non-coplanar points… maybe
this is the proble, I don’t know.
Anyway, what happens is that when I light the surface,
part of it is kinda missing, with “scratches” in it, or
rather black lines that go in the z direction and obscure
the near side of the surface (you can see through to
the other side of the surface)
What could be causing this? thought?
thanks much!
