Transforming 2D MNIST into rich 3D geometries (watertight meshes, sparse SDFs, and 6D normal-oriented point clouds) with continuous flow matching generative pipelines.
Continuous 3D surface extraction from sparse voxel grids. SimpleSparseVAE compresses sparse Signed Distance Fields into a 16-channel latent grid, decoded into continuous watertight triangle meshes via differentiable marching cubes.
