Tutorial on OpenGL texture formats
- by Cyan
Looking at the documentation glGetTexImage(), one can see that there are plenty of available texture formats.
GL_TEXTURE_1D, GL_TEXTURE_2D, GL_TEXTURE_3D, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY, GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP_POSITIVE_X, GL_TEXTURE_CUBE_MAP_NEGATIVE_X, GL_TEXTURE_CUBE_MAP_POSITIVE_Y, GL_TEXTURE_CUBE_MAP_NEGATIVE_Y, GL_TEXTURE_CUBE_MAP_POSITIVE_Z, and GL_TEXTURE_CUBE_MAP_NEGATIVE_Z
I've only used GL_TEXTURE_2D for the time being.
Is there any place / documentation where one can learn about these other formats ?
PS : and yes, of course, i've googled for it, results are pretty poor
