Version 3

WARNING: This version is not compatible with the previous one and all .PLY's must be reimported and new example scene must be used

1. Improved .PLY importer
   • Import multiple .PLY files at the same time
   • Creating prefabs for splats for ease of use with all required meshes/materials already generated
   • Optionally disable usage of correct sRGB color space (removes 2 grab passes but makes transparency incorrect)
   • Optional multi-chunk rendering. Splits the gaussian splat material into chunks of N splats (760k by default). Can improve performance.
   • Optionally add an alpha stencil mask between each pass to occlude any following splats from next chunks. Can improve performance.
   • Import with optional presorting.
2. Presorted rendering order.
   • Instead of using radix sort to sort by camera distance, presort the splats along 20 octahedral directions and save those sorting indices as a texture (requires a lot of texture memory).
   • This has the benefit of working standalone by itself anywhere, including avatars, however the rendering quality will be reduced because popping will happen when you rotate your camera.
   • Note that a splat prefab imported with this will no longer work with GaussianSplatRenderer.
3. More options in the GaussianSplatRenderer.
   • You can now specify how many bits of precision for the distance sort to do. Can be useful for huge scale splats.
   • Some parameters of the gaussian splat materials can be overridden from this component now
   • Quality Toggles have been added to the example scene to control the performance/quality tradeoff of rendering (by changing the gaussian cutoff value)
4. Rendering quality has been slightly improved.
   • There should be fewer rotating quad artifacts now, as the splat cutoff is exactly an ellipse now.
   • Projection accuracy has been improved, fewer jitter/missing splat artifacts should happen.
5. Performance improvements.
   • General performance improvements
   • Can additionally get more performance by using multi-chunk rendering and alpha stencil mask. This might not help for all splats scenes.

New release with lots of fixes

• Stable ellipsoid projection via fake doubles
• Faster performance
• Fixed bugs with missing/duplicated splats
• Using correct colorspace for splats
• Better U# script with more features that supports selection between different splats
• Improved example scene
• Splatting order now is much more stable, sorting against quantized camera positions (reduces popping jitter)
• Better quantization for assets, slightly lower size
• Better sorting precision, nonlinear distance quantization
  PS you need to reimport your .ply assets, old format is not compatible
