Resonite Introduces Native Gaussian Splat Support: Import, Edit, and Render in VR

Resonite, an online virtual world platform developed by Yellow Dog Man Studios, has introduced native support for Gaussian Splats, expanding its robust suite of 3D content creation and rendering tools. This update enables users to import, render, and perform basic edits on Gaussian Splats, further enhancing Resonite’s capabilities in high-fidelity scene reconstruction.

Launched in October 2023, Resonite offers a comprehensive platform for creating, learning, and exploring within immersive virtual environments. Users can interact through custom 3D avatars, build worlds collaboratively in real-time, and utilize a variety of in-game tools for content creation. Designed primarily for virtual reality headsets, Resonite also supports a desktop mode for mouse and keyboard users. ​

Gaussian Splatting is a Radiance Field representation, capable of reconstructing lifelike 3D from a series of 2D images.

Key Features of Resonite’s Gaussian Splat Support

• Import & Rendering: Users can import Gaussian Splats in PLY and SPZ formats, with support for both desktop and VR rendering.

• Basic Editing Tools: Clipping functionalities enable users to refine splats using bounding boxes or spherical constraints.

• Export Capability: Edited Gaussian Splats can be exported back into PLY or SPZ formats.

• Performance Considerations: Gaussian Splats require substantial GPU and VRAM resources. Users should manage large splats carefully, particularly in complex scenes.

• Rendering & Sorting Adjustments: The current implementation uses a less efficient sorting algorithm due to Unity engine limitations. A configurable setting allows users to balance GPU load and visual fidelity. Future updates will introduce VRAM compression to improve performance.

Additional Tools for Developers

Resonite’s update includes several features for those working with Gaussian Splats in more technical or diagnostic capacities:

• GaussianSplatRenderer: Enables adjustments to splat size, opacity, and spherical harmonics for testing and optimization.

• StaticGaussianSplat: Provides simple editing options such as bounding box and sphere clipping.

• GaussianSplatExportable: Supports exporting edited splats.

• DiagnosticGaussianSplat: Allows procedural definition and manipulation of individual splats for debugging and learning.

Future Improvements

Further optimizations, including VRAM compression, are expected to improve efficiency and reduce memory usage. As Resonite transitions away from Unity, rendering performance may also benefit from more advanced GPU features.

Users are encouraged to explore the new capabilities and provide feedback on performance and functionality. People can download Resonite from Steam.
