怎么上手

由 README 提炼，执行前请确认

原文

下载或克隆仓库后在 Blender 中 File → Append → NodeTree → GeometryNodesTree，再在几何节点编辑器 Shift+A → Group → GeometryNodesTree 添加节点组

硬件要求按 README 说明

README 未说明具体显存或 GPU 型号要求，仅要求 Blender 4.3+，支持 Windows / macOS / Linux。

支持 Apple Silicon

Blender 节点工具，用于加载预览 3DGS/4DGS 点云并设计相机运动

在 Blender 里轻量查看高斯泼溅数据、设计相机运动轨迹，并把配置导出给外部高斯渲染器使用。

核心能力

加载并可视化 3DGS 与 4DGS 的 .ply 文件
内置基础着色器预设，支持风格化或解析式预览
通过 Frame_Index 参数或 #frame 绑定控制 4DGS 播放
可作为几何节点组追加进自定义 Blender 管线
支持在 Cycles 与 Eevee 中做高斯渲染探索

容易踩的坑

4DGS 的 .ply 若含名为 t 的属性需先改名为 ttt，否则 Blender 会静默忽略；需自行准备 3DGS/4DGS 的 .ply 数据文件，仓库仅含示例 4D corgi 资产；需新建 collection 存放 seq05 并将其排除出渲染可见性

The UGRS 4D Gaussian Splatting project is now officially live on the Blender Demo Files page

Demo Banner

Cycles native ray-traced Gaussian rendering in an infinite mirror environment.

Real-time 4DGS bullet-time effect rendered entirely in Eevee.

This demo is part of the SIGGRAPH 2025 Real-Time Live! “InfiniteStudio: 4D Volumetric Capture for Filmmaking and Beyond” showcase, recognized with the Best in Show award.

Overview

A custom Blender node originally developed by Mediastorm during the ASUS 4DGS Yungang Grottoes project. It supports loading and previewing of 3D Gaussian Splatting (3DGS) and 4D Gaussian Splatting (4DGS) datasets,

providing basic visualization styles for quick inspection and camera motion design. This viewer represents an early component of the Universal Gaussian Rendering System (UGRS), a broader R&D effort exploring unified Gaussian rendering and visualization workflows.

Its technology was later featured in the SIGGRAPH 2025 Real-Time Live! showcase “InfiniteStudio: 4D Volumetric Capture for Filmmaking and Beyond” — which received the Best in Show Award.

Features

Load and visualize .ply files for 3DGS and 4DGS Basic shader presets for stylized or analytic previews Easy to integrate into custom Blender pipelines Experimental visualization for dynamic 4DGS sequences

Requirements

Blender 4.3+

Platform: Windows / macOS / Linux

How to Use

Clone or download this repository.

Add the provided assets into your Blender scene collection.（The sample project already includes a 4D corgi .ply asset.）

Create a new collection to store seq05 and exclude it from rendering visibility.

If using a new project: Go to File → Append → NodeTree → GeometryNodesTree Add the node group in the Geometry Nodes editor via Add (Shift + A) → Group → GeometryNodesTree
Load the 3DGS/4DGS .ply file through the node’s file path input, and ensure the parameters match the reference setup.

Control playback via the Frame_Index_input parameter. You can keyframe it manually or enter #frame to bind it to the current timeline frame.

⚠️ Important: If your 4DGS .ply file contains an attribute named t, rename it to ttt before import — Blender silently ignores attributes named t due to internal parsing rules.

🔬 Technology Exploration

Mediastorm’s ongoing R&D explores advanced Gaussian rendering within Blender’s ecosystem, bridging procedural rendering, real-time lighting, and volumetric representation.
