Assignment 3

1.5. Volume rendering (30 points)

2. Optimizing a basic implicit volume

2.1. Random ray sampling (5 points)

Box center: (0.25, 0.25, 0.00)

Box side lengths: (2.01, 1.50, 1.50)

2.3. Visualization

The top is TA results, the bottom is mine.

3. Optimizing a Neural Radiance Field (NeRF) (30 points)

4. NeRF Extras (Choose at least one! More than one is extra credit)

4.1 View Dependence (10 pts)

The drawback of view dependence is that it is easier to overfit to the training viewpints. This is because the view direction features of the novel views are never been seen during training.

The advantage is that it can better handle the spatial-varying effect (e.g., Specularity) since the direction information is encoded.

4.3 High Resolution Imagery (10 pts)
