Narrow
Class that provides an interface for doing precise collision detection against the broad and then the narrow phase. Unlike a BroadPhaseQuery, the NarrowPhaseQuery will test against shapes and will return collision information against triangles, spheres etc.
C++ JPH::NarrowPhaseQuery.
Functions
Cast a ray and find the closest hit. Returns true if it finds a hit. Hits further than ioHit.mFraction will not be considered and in this case ioHit will remain unmodified (and the function will return false). Convex objects will be treated as solid (meaning if the ray starts inside, you'll get a hit fraction of 0) and back face hits against triangles are returned. If you want the surface normal of the hit use Body::GetWorldSpaceSurfaceNormal(ioHit.mSubShapeID2, inRay.GetPointOnRay(ioHit.mFraction)) on body with ID ioHit.mBodyID.
Cast a ray, allows collecting multiple hits. Note that this version is more flexible but also slightly slower than the CastRay function that returns only a single hit. If you want the surface normal of the hit use Body::GetWorldSpaceSurfaceNormal(collected sub shape ID, inRay.GetPointOnRay(collected fraction)) on body with collected body ID.
Cast a shape and report any hits to ioCollector
Collect all leaf transformed shapes that fall inside world space box inBox
Check if inPoint is inside any shapes. For this tests all shapes are treated as if they were solid. For a mesh shape, this test will only provide sensible information if the mesh is a closed manifold. For each shape that collides, ioCollector will receive a hit
Collide a shape with the system
Same as CollideShape, but uses InternalEdgeRemovingCollector to remove internal edges from the collision results (a.k.a. ghost collisions)
Initialize the interface (should only be called by PhysicsSystem)
