Application --- Binary Space Partition (BSP)

Three points in 3-space define a plane . The images of these points, together with the epipoles, provide the four correspondences necessary to compute the compatible transformation for . That is, the projective transformation such that

transfers points coplanar with . Given it is then possible to distinguish points in 3-space on either side of , using only their image projections and i.e. a binary partition of 3-space.

BSP 1

Selected planar points, on one side and on the other side
