I want to use glOrtho (or gluOrtho) to set up my projection to render a UI.
If I use glOrtho(0,w,0,h,-1.0f,1.0f), where
w = width of window and
h = height of window
I works, but the origin is at the bottom left.
I would really like it at the top left, but
glOrtho(0,w,h,0,-1.0f,1.0f)
doesn''t seem to work (no display).
Shouldn''t this work, and if not, hot could I achieve what I want.
Thank you.
thanks, I didn''t think about culling. The different Projections reverse the winding order, so they got culled. anyway I disabled culling, and it works.
