IBRNet: Learning Multi-View Image-Based Rendering [PDF]
Computer Vision and Pattern Recognition, 2021 We present a method that synthesizes novel views of complex scenes by interpolating a sparse set of nearby views. The core of our method is a network architecture that includes a multilayer perceptron and a ray transformer that estimates radiance and ...

A Generative Model for Volume Rendering [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2017 We present a technique to synthesize and analyze volume-rendered images using generative models. We use the Generative Adversarial Network (GAN) framework to compute a model from a large collection of volume renderings, conditioned on (1) viewpoint and ...
