New program... parametric surfaces

Hi Stan,

my apologies but till 26th I am not able to dive in to the problem, but I remember in classic OpenGL the glRotatef rotations are always around "global axes", which is not usually what we want, that is why entity system has rotations around local axes, and I for sure did not used quaternions, but the transformations are custom made.

Hi Petr,

No worries at all... I understand!

I'll look at the entity system and see what I can find. I'm very close to having this problem figured out.

Cheers... and thanks!

Stan
