EG3D Results

Single Scene Overfitting, where 3d reconstruction of a single object takes place.

Below are the snapshots of the object from multiple angles

NeRF Results

Coarse sampling of the Rays - 64 samples per ray

Fine Sampling of the Rays - This uses hierarchical sampling as implemented in the Original paper

Analysis

The performance of EG3D is far better compared to the NeRF model (for whatever duration it has been trained on) as can be seen by the following side by side comparison.

Model Time Epoch
EG3D 1-2 days on a trained Tri-plane 200K
NeRF 3-4 days 2K
