There are more texture mapping approaches which can be added on top of normal mapping to make the illusion even better, such as parallax [1] or displacement [2]

- dragontamer 4y agoDisplacement mapping actually changes the mesh though, so its no longer a simple mapping that can be implemented in the pixel-shader step alone. ------ IMO, its important to understand the limitations of pixel shading, because its an important step in the modern graphics pipeline.
