1. A method for voxelizing a mesh representation associated with a three-dimensional model to generate a volumetric model, comprising: identifying a first voxel included in a voxel grid array that intersects with the mesh representation; selecting a second voxel at an exterior boundary of the voxel grid array that is not identified as a boundary voxel; marking the second voxel as an exterior voxel; marking all unmarked voxels that are adjacent to the second voxel as exterior voxels; marking all remaining voxels as interior voxels; and generating a volumetric model based at least in part on the first voxel.
