Hi there, I understand that in order to use texture mapping i need to texture map my bmp to some coordinate. However, what if i do not have any objects in my scene and only want the scene to have a texture, is this possible? How. what functions should i be looking into?
Do you have your scene models? If yes, what kind of format of it?
You could get a simple texture mapping example from here.
You probably want a sort of full screen texture ?
Well, just draw a big textured GL_QUAD covering the whole screen, without perspective.
