Fallout Software Tutorials Updated!

Greg Sidelnikov of FalloutSoftware.com has applied updates to his OpenGL tutorials. An entirely new article Normal Mapping Tutorial has been added providing several insights on what the pinkish/bluish colors actually represent. The difference between Immediate Mode (glBegin, glEnd) and the modern Vertex Buffer Object technique has been added to the Drawing OpenGL Primitives via VBO tutorial. Better diagrams have been improved in OpenGL Light tutorial. Greg is also planning to start adding GLSL fragment and vertex shader tutorials to the site soon. If this piques your interest you can subscribe to the tutorial newsletter on the site. Greg has been hosting OpenGL tutorials since 2003.
