A system and method for surface rendering and for the display and analysis of arbitrary structures within the interior of a solid body is presented. The method uses as a starting point a voxel element (200) which is known to be crossed by a surface of interest (220). The surface is rendered in a topologically consistent way by connecting encountered surface hits (230) at each voxel face. A pair of voxel face hits, surrounding a vertex value excceeding the surface value are used to form a triangle, spun around a third articulating point in the interior of the voxel (240). Voxel faces sharing the surface hits are sequentially examined, and a set of approximation triangles is formed, to build a triangularization grid (250). The rendered surfaces are interactively displayed (280) and analyzed for global structure properties.
