This project runs on all Blender-supported platforms — Windows, macOS, Linux, and the iPad version.
It is released under the CC-BY 4.0 license; proper attribution is required when referencing or reusing any part of this demo, especially the included node groups and shaders.
Overview
This Blender project contains two preconfigured scenes demonstrating real-time 4D Gaussian Splatting inside Blender using both Eevee and Cycles renderers.
Simply open the .blend file in Blender 5.0 or newer, enable Render View, and enjoy the effects.
1.
Scene “Nunchucks” (Eevee)
The default scene opened with the file.
Play the timeline to view the real-time 4DGS bullet-time effect rendered entirely in Eevee.
2.
Scene “The Cat” (Cycles)
Switch from the upper-right corner scene selector to “The Cat”.
Enter Render View to experience the Cycles native ray-traced Gaussian rendering in an infinite mirror environment.
Implementation Notes
This implementation differs from the standard Gaussian Splatting pipeline.
Due to Blender’s node system characteristics, this demo employs a custom Gaussian transparency evaluation method specifically designed for Blender’s architecture.
•
Each Gaussian is enclosed within a Point Cloud or Mesh object that shares a unified shader.
•
All transparency evaluation occurs in 3D space, making it ray-dependent rather than camera-dependent.
•
This allows a single node tree to work seamlessly in both Eevee and Cycles.
Typical usage:
•
Use Point Cloud mode in Eevee for the best real-time performance.
•
Switch to Mesh mode inside the node group when rendering in Cycles, or optionally in Eevee if you want fully unbiased rendering results.
