WebJan 4, 2024 · The reason that the search time correlates with the AABB size is that a larger AABB size means a query is enclosed by more AABBs; thus, the corresponding ray intersects more AABBs. More ray-AABB intersections translate to more BVH traversals on the RT cores (step 1 in the algorithm), which in turn leads to more IS calls on the SMs … WebMay 29, 2024 · You probably noticed I didn’t use the cross-product function. Since the AABB is axis-aligned, we know the three axes will always be (1, 0, 0), (0, 1, 0) and (0, 0, 1). So, as an optimization, I hardcoded the results of the cross-products. Check the intersection with those 9 axes, the 3 AABB face normals and the triangle face normal. WebThe intersection with a ray can be computed based on t ...

"WebThe arguments are interpreted as follows: origin is the start point of the ray.; unitDir is a unit vector defining the direction of the ray.; maxDist is the maximum distance to search along the ray. It must be in the [0, inf) range. If the maximum distance is 0, a hit will only be returned if the ray starts inside a shape, as detailed below for each geometry. " - Ray-aabb intersection normal

WebThe core of this method is a new algorithm for computing the intersection point and normal of a 3D ray with an arbitrarily-oriented 3D box, which also has non-rendering applications in GPU physics, such as ray casting and particle collision detection. We measured throughput improvements of 2× to 10× for the intersection operation versus ... WebAside from the ray being cast, all these ray-casting methods take a few extra parameters for controlling the behavior of the ray-cast: max_toi: is the maximum "time-of-impact" that can be reported by the ray-cast.The notion of "time-of-impact" refer to the fact that a ray can be seen as a point starting at ray.origin moving at a linear velocity equal to ray.dir.
