A new free program called NMG by Marabese Nilo will let you generate tangent space normal maps which can then be used for normal mapping, a technique used in games such as Doom 3 and Unreal 3 to give objects more detail without more polygons. The program requires a video card that supports the GL_ARB_fragment_program extension, which on the Macintosh is a Radeon 9550 or better, or an nVidia 5200 or better. Previously, only high end game engines such as Unity could generate normal maps on Mac OS X, as tools such as nVidia’s Adobe Photoshop plugin were available for Windows only. This program is a welcome addition to any Mac OS X OpenGL developer’s arsenal!
