gCoRF: Generative Compositional Radiance Fields
Mallikarjun BR, Ayush Tewari, Xingang Pan +2
3D generative models of objects enable photorealistic image synthesis with 3D control. Existing methods model the scene as a global scene representation, ignoring the compositional…
Generalized metric tree arrangements and Dressians
Ayush Kumar Tewari
Metric trees and metric tree arrangements index cones in the polyhedral fan structure in the Dressian and respectively. We introduce the notion of generalized m…
Neural Radiance Transfer Fields for Relightable Novel-view Synthesis with Global Illumination
Linjie Lyu, Ayush Tewari, Thomas Leimkuehler +2
Given a set of images of a scene, the re-rendering of this scene from novel views and lighting conditions is an important and challenging problem in Computer Vision and Graphics. O…
Neural Groundplans: Persistent Neural Scene Representations from a Single Image
Prafull Sharma, Ayush Tewari, Yilun Du +7
We present a method to map 2D image observations of a scene to a persistent 3D scene representation, enabling novel view synthesis and disentangled representation of the movable an…
GAN2X: Non-Lambertian Inverse Rendering of Image GANs
Xingang Pan, Ayush Tewari, Lingjie Liu +1
2D images are observations of the 3D physical world depicted with the geometry, material, and illumination components. Recovering these underlying intrinsic components from 2D imag…
Disentangled3D: Learning a 3D Generative Model with Disentangled Geometry and Appearance from Monocular Images
Ayush Tewari, Mallikarjun B R, Xingang Pan +3
Learning 3D generative models from a dataset of monocular images enables self-supervised 3D reasoning and controllable synthesis. State-of-the-art 3D generative models are GANs whi…
Characterization of tropical planar curves up to genus six
Ayush Kumar Tewari
We provide new forbidden criterion for realizability of smooth tropical plane curves. This in turn provides us a complete classification of smooth tropical plane curves up to genus…
FIRe: Fast Inverse Rendering using Directional and Signed Distance Functions
Tarun Yenamandra, Ayush Tewari, Nan Yang +3
Neural 3D implicit representations learn priors that are useful for diverse applications, such as single- or multiple-view 3D reconstruction. A major downside of existing approache…
