1. A method comprising: receiving a surface at a processing engine; mapping, by the processing engine, the surface onto a plurality of volumetric picture elements (voxels) by: projecting the surface onto a two dimensional plane associated with a major dimension of a normal to the surface, selecting a subset of voxels in the plurality of voxels based on the projection of the surface, dividing the subset of voxels into one or more columns of voxels, and for each column of voxels, tagging each voxel in the column of voxels associated with a crosshair shape that intersects any point on the surface; and generating, by the processing engine, a value for each voxel in the plurality of voxels that is tagged, wherein a voxel intersects with the surface when the surface intersects the crosshair shape associated with the voxel, and wherein the processing engine is at least one of a software engine executed by a processor or a hardware engine included in the processor.
