Gaussian Splatting Unity Plugin Updated

Aras Pranckevičius, programmer and creator of a Gaussian Splatting Unity Plugin has released an update to the plugin. Despite previously stating that he is no longer actively developing the Unity plugin, the MIT License allows users to build upon Aras’s work. This recent update is a testament to that, stemming from Github user b0nes164’s efforts.

Please note the following updates:

• Splat editing tools are now the Unity “editor tool context” thing (blob looking icon atop of regular tools toolbar).

• Can now move individual selected splats.

• When multiple splat objects are selected, they can be merged into one larger splat cloud.

• Add “Reset” button to revert edits back to asset state.

Export:

• Option to “bake” (i.e. apply) whole object transformation into the exported PLY file. This included proper rotation of Spherical Harmonics data.

Rendering:

• Faster GPU sorting routine, AMD FidelityFX 4-bit radix sort was changed to “reduce-then-scan” 8-bit radix sort. On RTX 3080Ti, sorting 6.1 million splats goes from 2.4ms down to 1.1ms.

• Add option to visualize only the spherical harmonics contribution, without regular color.

• ⚠️ Note: splat asset format has changed, need to re-create the splat assets.

Additionally, Aras participated in the Metaverse Standards Forum on February 7th, where he provided an overview of Gaussian Splatting, its workings, and more!
