WebSphere tracing is a version of the ray casting algorithm [2]. It relies on the geometry being dened as signed distance functions (SDFs), and does not directly support the import of standard 3D Polygonal geometry or meshes. One of the advantages lies in the algorithm's potentially improved speed in comparison to xed-step ray casting. Webexp(trace(XT AplusX)): The Bingham distribution on the unit sphere in Rq can be simulated using (a) rBingham, (b) rFisherBingham with mu=0, and (c) rBingham.Grassmann with r=1.
