Abstract
We present an illustrative rendering extension for virtual endoscopy to enhance depth perception. For this purpose different hatch textures are applied and their ability to enhance 3D shape estimation is discussed. The stroke directions of the textures are aligned to the principal curvature directions of the surface. Starting with two patterns suggested by Kim et al. [1], we developed texture patterns for the use in our virtual endoscopy system. Altogether five different hatch textures are integrated within the framework and OpenGL-generated mipmaps are applied to account for aliasing effects on the textured surfaces.
