Visionary

Visionary is an open, web-native platform built on WebGPU and ONNX Runtime for real-time rendering of diverse Gaussian Splatting variants (3DGS, MLP-based 3DGS, 4DGS, Neural Avatars and any future algorithms) and traditional 3D Mesh, directly in the browser.

Features

• Native WebGPU Powered: Utilizes WebGPU to achieve high-performance parallel sorting and rendering of millions of Gaussian particles.
• Hybrid Rendering Architecture: Automatically handles depth mixing (Depth Compositing) between Gaussian point clouds and standard Meshes, perfectly solving occlusion issues and supporting complex scene compositions.
• Universal Asset Loader: Single interface to intelligently identify and load multiple formats:
  • Static Gaussians: PLY, SPLAT, KSplat, SPZ, SOG
  • Standard Mesh Models: GLB, GLTF, FBX, OBJ
  • 4DGS/Avatar/scaffold-GS: ONNX
  • Custom Algorithms: Export your own algorithm to ONNX format

Development Guide

1. Core Foundations

The cornerstone of building applications. This chapter covers:

• Environment Initialization: Configuring ONNX Runtime (ORT) and WebGPU Context.
• Universal Loader: Detailed explanation of the loadUnifiedModel interface and intelligent file format detection mechanisms.
• Resource Management: Reuse strategies for Gaussian renderers and memory management.

2. Object & Interaction

Mastering model control. This chapter covers:

• Gaussian Objects (GaussianModel): Property control (Transform, Opacity, Cutoff).
• 4D Animation: Timeline control, Play/Pause, and dynamic inference updates.

3. Rendering Pipeline

Deep dive into the engine internals. This chapter covers:

• The Hybrid Loop: Understanding the execution order of Scene Pass -> Depth Capture -> Splatting.
• GaussianThreeJSRenderer: Detailed API explanation of the core rendering coordinator.
• Depth & Occlusion: How Auto Depth Mode works.
