WebJul 1, 2024 · A BVH4 or BVH8 would normally be created by collapsing a regular BVH (a BVH2 if you will); that way, you keep the adaptive planes and the object partitioning. Octrees split at a fixed point and they split space, so primitives can be in multiple nodes. You can expect significantly better ray tracing performance from a BVH, see my post on SAH. JoeJ The BVH is an acceleration structure. It serves to reduce a pretty fundamental problem in ray tracing: the sheer cost of finding the nearest intersection of a ray and a scene consisting of (potentially) millions of polygons. The basic principle is easy to understand: if we have 64 polygons, we could split them into two … See more On my machine, it takes about 140 milliseconds to construct the 640 x 640 rays and intersect them with the 64 triangles. That’s not … See more We can now start the actual construction of the hierarchy. The first step is the creation of the root node, which we will then recursively subdivide. The first lines of this function initialize the centroids for the triangles, which … See more Time to put the BVH to work. Traversing it is of course a recursive process, starting at the root node: 1. Terminate if the ray misses the AABB of this node. 2. If the node is a leaf: … See more There is one nagging oversight in the partition code that we need to fix. I am talking about this line: This line has two issues. First, we are changing the original list of triangles. This … See more

WebDec 15, 2024 · As a result, using discrete LODs is the only option, but currently this means to build independent BVH for each level of a model, so LOD likely gives no speed up in practice and not worth it. Now we could say that current games do not really use LOD. Levels are still designed to limit draw distance.
