A complete treatment of D1 discontinuities in a discontinuity mesh

This paper presents a treatment of first-order discontinuities (D1) that arise in discontinuity meshes. An algorithm is described that, given a planar D1 discontinuity surface in a polyhedral scene, computes the corresponding discontinuity curves on the faces of the scene. A method is described to efficiently update the backprojection across a D1 discontinuity curve. An alternative update method is presented which is novel and numerically robust.
