    In this paper, a new method based on a quadtree decomposition is proposed for rendering CSG modeled solids. A surface parametric description is stored in a quadtree (VST) whose nodes represent parametric patches. Object description allows a non-polygonal boundary representation that provides more accurate point sampling information for the rendering process. The visible surface tree (VST) is built and updated at CSG edition time. Traversal is performed when a realistic object image is required.
