Cartoon Shading Course: Game Programming
Introduction
This is a project for the course: Game Programming. A program that can read .3ds models and present real-time cartoon shading is developed. Vertex and fragments shaders are programmed in Cg (C for graphics) to utilize the power of gpu computing.
Contour
The contour is gained by applying a sobel operator to the normal texture of the model.
Cartoon Shading
In cartoon shading, the result of lighting is not continuous, thus the effect of cartoon shading can be achieved using a piecewise function that maps continuous values from 0 to 1 to discontinuous values.
