We propose a versatile pipeline to render B-Rep models interactively, precisely and without rendering-related artifacts such as cracks. Our rendering method is based on dynamic surface evaluation using both tesselation and ray-casting, and direct GPU surface trimming. An initial rendering of the scene is performed using dynamic tesselation. The algorithm we propose reliably detects then […]

Realism and real-time visual and haptic interactions with anatomical structures are key challenges in simulation software for surgeries. Overcoming these challenges is made difficult by the need to run the software on consumer-grade computing platforms. This paper presents preliminary work towards a framework for fast, realistic and stable simulation of deformable anatomical structures. The approach […]

Presently, dynamic surface-based models are required to contain increasingly larger numbers of points and to propagate them over longer time periods. For large numbers of surface points, the octree data structure can be used as a balance between low memory occupation and relatively rapid access to the stored data. For evolution rules that depend on […]
