Cartoon Rendering on the Radeon®
|
|
|
The RadeonCartoon demonstrates two different techniques for rendering cartoon like objects from 3D models. The first technique uses a spheremap shown in figure 1. Using this sphere map areas with sharp curvature are colored using the edges of the sphere map giving a black line in those areas. The results of this techinque are shown in figure 2.

The second technique uses ARB_texture_cube_map to give a more brushed looking effect. The X and Y sides of the cubemap look similar to figure 3 the near Z cubeface is white and the far Z cubeface is black. The results are show in figure 4
