Learning Smooth Neural Functions via Lipschitz Regularization
The latent descriptor of a neural field acts as a deformation handle for the 3D shape it represents.
Spelunking the Deep: Guaranteed Queries for General Neural Implicit Surfaces
Neural implicit representations, which encode a surface as the level set of a neural network applied to spatial coordinates, have proven to be remarkably effective for optimizing, compressing, and generating 3D geometry.
Neural Shape Mating: Self-Supervised Object Assembly with Adversarial Shape Priors
To train NSM, we present a self-supervised data collection pipeline that generates pairwise shape assembly data with ground truth by randomly cutting an object mesh into two parts, resulting in a dataset that consists of 19, 226 shape assembly pairs with numerous object meshes and diverse cut types.
Neural Geometric Level of Detail: Real-time Rendering with Implicit 3D Shapes
We introduce an efficient neural representation that, for the first time, enables real-time rendering of high-fidelity neural SDFs, while achieving state-of-the-art geometry reconstruction quality.
Complementary Dynamics
Our method does not require a particular type of rig and adds secondary effects to skeletal animations, cage-based deformations, wire deformers, motion capture data, and rigid-body simulations.
Learning Deformable Tetrahedral Meshes for 3D Reconstruction
We introduce Deformable Tetrahedral Meshes (DefTet) as a particular parameterization that utilizes volumetric tetrahedral meshes for the reconstruction problem.
On the Effectiveness of Weight-Encoded Neural Implicit 3D Shapes
Many prior works have focused on _latent-encoded_ neural implicits, where a latent vector encoding of a specific shape is also fed as input.
Neural Subdivision
During inference, our method takes a coarse triangle mesh as input and recursively subdivides it to a finer geometry by applying the fixed topological updates of Loop Subdivision, but predicting vertex positions using a neural network conditioned on the local geometry of a patch.
NiLBS: Neural Inverse Linear Blend Skinning
In this technical report, we investigate efficient representations of articulated objects (e. g. human bodies), which is an important problem in computer vision and graphics.
Learning to Predict 3D Objects with an Interpolation-based Differentiable Renderer
Many machine learning models operate on images, but ignore the fact that images are 2D projections formed by 3D geometry interacting with light, in a process called rendering.

Beyond Pixel Norm-Balls: Parametric Adversaries using an Analytically Differentiable Renderer
As such, we propose the direct perturbation of physical parameters that underly image formation: lighting and geometry.
