Who is James Blinn?
James Blinn is a computer scientist who created new ways to generate 3 dimensional images in computer graphics in 1978. He has been described as a bridge in the gap between art and science, as he has worked for the US Space Agency NASA, and in animation for tv series. He invented new methods to represent how objects and light interact in a virtual world, environment mapping and bump mapping.
What is a bump map?
Bump mapping ‘simulates the bumps or wrinkles in a surface without the need for geometric modifications to the model.’ It’s a method in computer graphics, of making a surface look more real by making it less smooth, as if it has bumps, wrinkles etc. Helping make it look more realistic.
