Task
Implementation of suggestive countours rendering for volumetric data in combination with direct volume rendering. The implementation should be fast and efficient, therefore GPU implementation using shaders is welcome (but not required).Description
Typically direct volume rendering (DVR) results in images, where features occlude each other. In order to reserve image space to more privileged/interesting features, some parts of the volume have to be represented in a more abstract way. Suggestive contours for polygonal representation have proven that they convey shape very effectively. This approach can be extended to support volumetric data.
