JAX3D enables hierarchical NeRF for advanced 3D rendering and reconstruction

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a method for creating hierarchical Neural Radiance Fields (NeRFs) using JAX and the jax3d library. This approach enables volumetric rendering, novel-view synthesis, and 3D reconstruction. The tutorial details the process of building a synthetic dataset, implementing a NeRF with positional encoding and hierarchical sampling, and training it using JAX's JIT compilation and Adam optimization. The results are evaluated using metrics like PSNR and visual outputs for depth, opacity, and extracted geometry. AI

IMPACT This implementation provides a practical guide for researchers and developers to leverage JAX and jax3d for advanced 3D computer vision tasks.

    Hierarchical NeRF with JAX3D for Volumetric Rendering, Novel-View Synthesis, and 3D Reconstruction

    <p>In this tutorial, we build an end-to-end hierarchical Neural Radiance Field (NeRF) using JAX, Flax, Optax, and the volume-rendering primitives provided by jax3d. We first construct a synthetic multi-view dataset from an analytic scene containing volumetric geometry and view-de…
