Abstract
A method for rendering a plurality of geometrically thin objects in a computer system includes receiving a plurality of points associated with each of the plurality of geometrically thin objects, determining a plurality of volumetric point densities associated with the plurality of geometrically thin objects in response to the plurality of points, determining a plurality of volumetric point density gradients in response to the plurality of volumetric point densities, determining a plurality of surface normals associated with at least a subset of points in response to the plurality of volumetric point density gradients, and performing a rendering operation for the subset of points in response to the plurality of surface normals.
