Webthe order induced by a BVH before the deformation occurred (e.g. the BVH from the previous frame), the BVH construc-tion of the deformed mesh will automatically take less time. In other words, by rebuilding from scratch each frame we put a lower bound on the quality of the trees we produce and an upper bound on the generation time. 2.3. WebBoth the BVH construction and ray traversal are easily implemented on GPUs and integrated into a GPU-based micropolygon renderer. In our experiments, our ray tracer performs up to an order of magnitude faster than the state-of-art rasterizers while consistently delivering an image quality equivalent to a maximumquality rasterizer.

WebOur method is an extension of the current state-of-the-art on GPU BVH construction, Treelet Restructuring Bounding Volume Hierarchy (TRBVH), and consists of optimizing an already existing tree by rearranging subsets of its nodes using a bottom-up agglomerative clustering approach. WebA bounding volume hierarchy ( BVH) is a tree structure on a set of geometric objects. All geometric objects, which form the leaf nodes of the tree, are wrapped in bounding volumes. These nodes are then grouped as small sets and enclosed within larger bounding volumes.

WebA BVH model was chosen over a KD-Tree as a BVH is more practical for dynamically changing environments as it is quick for the GPU to build. The stages of BVH construction are defined as follows: Morton Code Generation: Assign Morton Codes to the centroid point of each triangle’s bounding box.
