Abstract:
1. A system for generating a generalized displacement map (GDM) from arbitrary mesostructure geometries, comprising: providing a regular three-dimensional (3D) grid having a plurality of fixed points relative to an arbitrary mesostructure geometry comprising a plurality of volumetric triangles; adjusting mesostructure geometry sampling rates by increasing a point density of the regular 3D grid for reducing artifacts in the GDM resulting from high-frequency mesostructure details; from each point of the 3D grid, projecting a ray towards a plurality of predetermined viewing directions; for each viewing direction, recording a displacement distance along each ray from each 3D grid point to a nearest surface of the mesostructure geometry; and storing each of the recorded displacement distances as a GDM for the arbitrary mesostructure geometry.
