1. A computer-implemented method for constructing a three-dimensional (3D) model, comprising:
receiving a 3D topology definition for faces of cells within a volumetric mesh;
processing the 3D topology definition and the volumetric mesh according to parameters to predict a 3D model representation corresponding to a reference 3D model;
rendering the 3D model representation to produce a rendered image;
transporting rays corresponding to the rendered image through the 3D model representation to compute probability values for the cells; and
updating the parameters based on the probability values to reduce differences between the rendered image and a reference image of the reference 3D model.
