Module gpu_ray_tracing 

GPU ray tracing (CPU mock implementation).

Provides BVH construction, ray-AABB intersection (slab method), ray-triangle intersection (Möller-Trumbore), and BVH traversal.

Structs

Aabb

Axis-aligned bounding box (AABB).

BvhNode

A node in the bounding volume hierarchy.

HitRecord

Result of a ray-triangle intersection test.

Ray

A ray defined by an origin and a direction.

Triangle

A triangle defined by three vertices.

Functions

batch_ray_cast

Cast multiple rays against a BVH and return the closest hit for each.

build_bvh

Build a BVH from a list of triangles using bottom-up SAH-lite construction.

ray_aabb_intersect

Test whether a ray intersects an AABB using the slab method.

ray_triangle_intersect

Test whether a ray intersects a triangle using the Möller-Trumbore algorithm.

traverse_bvh

Traverse the BVH to find the closest ray-triangle intersection.
