Abstract: I will show several recent results on learning neural implicit 3D representations by departing from the traditional concept of representing 3D shapes explicitly using voxels, points and meshes. Implicit representations have a small memory footprint and allow for modeling arbitrary 3D toplogies at arbitrary resolution in continuous function space. I will show the abilitiy and limitations of these approaches in the context of reconstructing 3D geometry and textured 3D models and motion. Finally, I will also show results on learning implicit 3D models using only 2D supervision by deriving an analytic closed form solution to the gradient updates.
