Hi… everyone…
First, sorry for my english writing… I’m trying to program with opengl.
What I want to know is…
if I model a cube in 3d space…
how can I get and access real 3d coordinates? and how can I get and access 2d coordinates of its projection?
You can get 3D coordinates by multiplying coordinates on current MODELVIEW_MATRIX(which can be get by glGet) or by using glRenderMode(GL_FEEDBACK). You can get 2D coords using gluProject on your 3D coords.
