Where point (in the geometry's space) lies on triangleIndex
(three-mesh-bvh's getTriangleHitPointInfo): its face (vertex indices, face
normal, material index from the groups), its uv when the geometry has one,
and its barycentric weights. The weights are the core's
(barycoordOnTriangle, the point projected on the plane); a degenerate
triangle gets zero weights.
