SpletConsider a general 4x4 transform M (matrix stacks) Apply inverse transform M-1 to ray Locations stored and transform in homogeneous coordinates Vectors (ray directions) have homogeneous coordinate set to 0 [so there is no action because of translations] Do standard ray-surface intersection as modified Given a vector space V, there is a natural bilinear map V × V → F given by sending (v, φ) to the scalar φ(v). The universal property of the tensor product V ⊗ V automatically implies that this bilinear map is induced by a linear functional on V ⊗ V . Similarly, there is a natural bilinear map V × V → Hom(V, V) given by sending (v, φ) to the linear map w ↦ φ(w)v.
