Classes
struct	physics::HitscanHit
	Result of a hitscan raycast. More...
struct	physics::HitboxHit
	Skeleton-driven hitbox raycast (capsule-based). More...

Namespaces
namespace	physics
	Pure physics math — no ECS types, no registry.

Functions
bool	physics::raycastAABB (glm::vec3 origin, glm::vec3 direction, const WorldAABB &box, float maxDistance, float &outDistance, glm::vec3 &outNormal)
	Ray vs axis-aligned box intersection (slab method).
bool	physics::raycastCylinder (glm::vec3 origin, glm::vec3 direction, const WorldCylinder &cyl, float maxDistance, float &outDistance, glm::vec3 &outNormal)
	Ray vs vertical cylinder intersection.
bool	physics::raycastSphere (glm::vec3 origin, glm::vec3 direction, const WorldSphere &sph, float maxDistance, float &outDistance, glm::vec3 &outNormal)
	Ray vs sphere intersection.
bool	physics::raycastTriMesh (glm::vec3 origin, glm::vec3 direction, const WorldTriMesh &mesh, float maxDistance, float &outDistance, glm::vec3 &outNormal)
	Raycast against a triangle mesh using BVH-accelerated Möller-Trumbore.
bool	physics::raycastBrush (glm::vec3 origin, glm::vec3 direction, const WorldBrush &brush, float maxDistance, float &outDistance, glm::vec3 &outNormal)
	Ray vs convex brush intersection (generalised slab method).
HitscanHit	physics::raycastWorld (glm::vec3 origin, glm::vec3 direction, const WorldGeometry &world)
	Raycast against all static world geometry (planes + boxes + cylinders + spheres).
HitscanHit	physics::raycastPlayers (Registry &registry, entt::entity shooter, glm::vec3 origin, glm::vec3 direction, float maxDistance)
	Raycast against all player hitboxes (axis-aligned capsule approximation).
HitscanHit	physics::resolveHitscan (Registry &registry, entt::entity shooter, glm::vec3 origin, glm::vec3 direction)
	Full hitscan resolution: world geometry first, then players (closest wins).
bool	physics::raycastCapsule (glm::vec3 origin, glm::vec3 dir, glm::vec3 A, glm::vec3 B, float r, float maxDist, float &outDist, glm::vec3 &outNormal)
	Ray vs capsule intersection.
HitboxHit	physics::raycastPlayerHitboxes (Registry &registry, entt::entity shooter, glm::vec3 origin, glm::vec3 direction, float maxDistance)
	Raycast against all player hitbox capsules (skeleton-driven).
HitboxHit	physics::resolveHitscanHitbox (Registry &registry, entt::entity shooter, glm::vec3 origin, glm::vec3 direction)
	Full hitscan with skeleton-driven hitboxes.

Variables
constexpr float	physics::k_hitscanRange = 5000.0f
	Maximum hitscan distance in world units.
constexpr float	physics::k_parallelEpsilon = 1e-6f
	Epsilon for parallel-ray checks.

Detailed Description

Shared hitscan raycasting against world geometry and player hitboxes.

Used by both the server (WeaponSystem) and the client (local fire VFX). Functions are inline so this remains a header-only utility.
