encode, using a variational autoencoder that includes an encoder and a decoder, the voxelized three-dimensional objects into pairs of multi-dimensional vectors, wherein individual pairs include a vector of means and a vector of standard deviations;

create sampled multi-dimensional vectors having a particular dimensionality by sampling from the individual pairs of multi-dimensional vectors such that a first sampled multi-dimensional vector is created based on an encoding of the first voxelized object;
