Parallax Mapping Mod enhances Doom3's graphics engine by applying parallax mapping to all textures. Parallax mapping, also known as virtual displacement mapping, is a recent graphical technology that gives surfaces more depth and realism. Using a heavily modified vertex and pixel shader and a mix of custom and simulated height maps, this mod makes surfaces look more three-dimensional by offsetting bumps depending on your view. Although you may not see an obvious difference right away, look closely at surfaces and you will see an improvement compared to original Doom3. Most bumps will look like they're actually sticking out. This mod also works in user-made levels that have custom textures, and a tutorial is included to describe how to add optional height maps to your level for a true parallax effect. NOTE: This mod requires at least a Radeon 9500 or GeForce FX
