Also take a look at the *Average number of intersection tests per ray* statistic that the code outputs after rendering; this should be around 20X lower compared to the image you rendered in Task 1. If your image is correct, ... 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. WebWe provide a numerical approach to compute oriented bounding boxes (OBBs) and a robust method to perform ray/OBB intersection based on the Lorentz transform. We also show how to compute additional intersection information (normal, face ID, and UV coordinates).

WebFind the intersection of a ray and a plane. 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.

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.
