Function physx_sys::phys_PxFindFaceIndex

pub unsafe extern "C" fn phys_PxFindFaceIndex(
    convexGeom: *const PxConvexMeshGeometry,
    geomPose: *const PxTransform,
    impactPos: *const PxVec3,
    unitDir: *const PxVec3
) -> u32

Computes closest polygon of the convex hull geometry for a given impact point and impact direction. When doing sweeps against a scene, one might want to delay the rather expensive computation of the hit face index for convexes until it is clear the information is really needed and then use this method to get the corresponding face index.

Closest face index of the convex geometry.
