🎉 New Features​

3DGS File LoD Support (Lighter Rendering)​

When configuring 3D Gaussian Splatting (3DGS) files in Threedive AI Studio, you can now use the LoD (Level of Detail) option.

When this option is enabled, the following behavior occurs.

• Rendering processing may become lighter
  • Splats (elliptical plates) closer to the camera position will be displayed in more detail, while distant ones will be omitted. Especially for large 3DGS files, a reduction in processing load can be expected
• Loading time may become longer
  • Pre-calculation is performed after loading 3DGS files (excluding .rad files), so especially for large 3DGS files, loading time may be longer than usual

3DGS File Streaming Support (Faster Display Time for Spaces)​

We now support loading the .rad format as a 3DGS file.

If you convert existing 3DGS files to this format in advance, "streaming" of 3DGS becomes possible. When streaming is enabled, similar to streaming video playback like YouTube, files are gradually read while displaying, so display start becomes faster.

For more information about rad files, please see the following page
