One of the techniques used to accelerate rendering of 3D images is visibility culling, the process where the invisible is removed from the graphics pipeline at early stage. This can be implemented by using the method of Potentially Visible Sets (PVS), that pretabulates the visibility information, enabling rapid culling at run-time. The Visor SDK enables the PVS method to be used with high complexity 3D models. The PVS computation is implemented as a four-stage automatable pipeline and can be controlled via an OpenGL API-based GUI.
