Mesh processing workflow

• Use mesh-fusion to make mesh watertight. (Manifold-2 or point cloud utils can also work but mesh-fusion performs the best)
• Use GAPS or DeepSDF processing pipeline to generate near surface SDF samples
• Use point cloud utils to generate uniform SDF samples
• Use pyrender to render depth maps for watertight meshes
• Backproject depth map into point cloud and transform into world frame
