Hierarchical bounding volumes

WebThis invention integrates model simplification and bounding volume hierarchy construction for collision detection in interactive 3D graphics. In particular, it provides general framework and a preferred method to construct bounding volume hierarchy using outputs of model simplification. Simplified models, besides their application to multi-resolution rendering, … WebThe bounding volumes of all objects should be stored contiguously in memory. This results in more efficient CPU cache utilization and allows for further optimization using SIMD instructions. DICE has a whole presentation on this subject: Culling the Battlefield: Data Oriented Design in Practice
