Methods, systems, and computer-readable media for generating a cross-section of a 3D model are disclosed. An example method includes determining a cross-section plane intersecting the 3D model, performing ray-tracing by passing each of a plurality of rays through a corresponding pixel of a viewing plane such that each ray intersects the cross-section plane, determining one or more rays that are within a threshold distance of the 3D model at their respective points of intersection with the cross section plane, and highlighting pixels corresponding to the determined rays.

Visualizing and evaluating 3D cross-sections

A system, method, and computer program for storing a polygonal topology, comprising representing a primitive with a plurality of vertices, internal half-edges and external half-edges; and storing said plurality of vertices in a vertex array and said plurality of external half-edges in a half-edge array, wherein said arrays are indexed and parallel to one another; whereby said primitive is re-created from said parallel array with said internal half-edges that are implicit from a primitive structure and appropriate means and computer-readable instructions.
