In this chapter, we will cover the following recipes:

• Applying a 2D texture
• Applying multiple textures
• Using alpha maps to discard pixels
• Using normal maps
• Parallax mapping
• Steep parallax mapping with self shadowing
• Simulating reflection with cube maps
• Simulating refraction with cube maps
• Applying a projected texture
• Rendering to a texture
• Using sampler objects
• Diffuse image-based lighting
