Front and Backface different texture

OpenGL OpenGL: Basic Coding

Hi,

Google could unfortunatelly not help me on that. Is it possible to use a different texture for the front and backFace of a quad for example?
I guess so, but how?

Thanks

I don’t know if there is a built-in function for this, but it should be easy enough to do in a shader.

If you do not want to use shaders, enable culling then for the 1st pass draw geometry in GL_FRONT culling mode binding the right texture and for the 2nd pass draw once again geometry but with GL_BACK culling mode and binding another texture.
