Folks,
I am getting fimilar with my OpenGL programming since last Spring and successfully wrote a program to display planet Earth by using ECP spherical mapping (slices and rings division). Only problem is too tight grids near poles.
Now I researched about quadcube spherical programming for cubmap images through Internet. I found some pages but it do not have sample code about that quadecube grids. Without sample code, I did still not know how to implement code to display quadcube sphere through simple vertexes, indices, and texcoords for glDrawElements function call.
Does anyone have any sample/example codes for quadcube sphere mapping for cubemaps?
Thanks!
