UnityTriangleSplatting

Introduction

UnityTriangleSplatting is a Unity package for visualizing triangle splats from COFF files, inspired by the Triangle Splatting project. It supports chunked loading, frustum culling, and optional mesh collider generation for interactive exploration of large triangle datasets.

Features

• ✅ Load and render .off (COFF) triangle files
• ✅ Chunk-based loading for performance
• ✅ Frustum culling for real-time optimization
• ✅ Optional mesh collider generation
• ✅ Vertex color support for per-vertex shading

Example

!Triangle Splatting Example

💡 You can drag and drop your own .off files into the scene and assign a material with vertex color support.

Installation

1. Clone this repository:

   git clone https://github.com/YourUsername/UnityTriangleSplatting.git

   Open your Unity project. Drag the TriangleSplatRenderer.cs script and the Shaders folder into your project. Assign a material using the included VertexColor.shader to your triangle splats. Usage Add the TriangleSplatRenderer component to an empty GameObject. Set the path to your .off file. Assign a material that supports vertex colors. Press Play to visualize the triangle splats in the scene.
