GPU Supported 3D Character Model Rendering of Chinese Painting Effects

We adopt a spherical texture mapping technique to simulate the varied width of the stroke on the outlines of the models and eliminate the black area that may appear on the model surface in certain situations.The brightness of the stroke is controlled by the dot product between viewing direction and the normal direction of the surface.We achieved rea-l time rendering of 3D character models and walk-through of characters in a 3D scene.
