# TruncGradGS

Synthetic dynamic benchmark released with [TruncGradGS: Improved 3D Gaussian Splatting via Truncated Gradient Updates](https://dubiouscactus.github.io/trunc-grad-gs/) (Pacific Graphics 2026).

The benchmark is six path-traced scenes with large motion: fluids, foliage, night lighting, particles, and caustics. Each scene is 300 frames (10 s at 30 fps) at 1600×900. Cameras are arranged in rigs of several circular arrays. Evaluation holds out 1–4 cameras per scene; the remaining cameras are the training views.

**Five scenes are in this repo as Parquet files.** The underwater scene (`1_4_underwater`) is **coming soon**.
