Visualization issues in virtual environments: From computer graphics techniques to intentional visualization
In Proceedings of the 9th international conference in central europe on computer graphics, visualization and computer vision (WSCG)
Abstract
Rendering efficiently large virtual environment scenes composed of many elements, dynamic objects, and a highly moving viewpoint is a major issue. This paper focuses on the first of the two viewing stage operations: required elements determination, the second being shading/filtering. We propose a classification, extending the existing computer graphic techniques toward display scalability requirements, that distinguishes two key points: keeping only required elements (culling), and keeping only required details (which includes traditional LODs). The mechanisms needed for display scalability are presented.
