Module gpu_collision_detection 

GPU-accelerated collision detection (CPU mock backend via Rayon).

Implements a broadphase AABB sweep-and-prune followed by a narrowphase sphere-sphere test and a stub GJK dispatcher. The “GPU” dispatch is mocked using Rayon parallel iterators so the module compiles and runs on CPU.

Structs

Aabb

Axis-aligned bounding box.

GpuCollisionBuffer

Buffer holding the AABB list and broadphase potential pairs.

Sphere

Sphere descriptor: centre + radius.

SphereContact

Sphere-sphere narrowphase collision result.

Enums

GjkResult

Stub result from the GJK narrowphase.

Functions

batch_gjk_dispatch

Dispatch GJK for a batch of collision pairs (stub implementation).

build_collision_pairs

Build the full broadphase collision pair list from a sorted AABB list.

gpu_aabb_overlap

AABB-AABB overlap test kernel (mock GPU dispatch).

gpu_broadphase_sort

Sort AABBs by their minimum x-coordinate (mock GPU sort).

gpu_sphere_collision

Test sphere-sphere collisions for the given pairs (mock GPU narrowphase).
