A Gaussian Splat is a volumetric 3D point cloud cluster Asset that looks like a regular Mesh from a distance, but may look more fuzzy up close. This provides more detail than regular triangles in traditional computer graphics, by using blobs in 3D space.
There is a discussion thread to this feature here on the Resonite Discord server: Gaussian Splats Discussion
Common Uses
Gaussian Splats are useful for applications and cases where you want:
- Photo realistic environments or objects
- Film sets & locations
- Alternative 3D rendering techniques
- Bringing in 3D scans
Some sites that allow for editing and viewing Gaussian Splats:
Importing
To import a Gaussian Splat asset, check Gaussian Splat Import for details.
Creating & Editing
This is the closest known tutorial for creating and importing Gaussian Splats into an engine (please ignore the unreal engine portion, every other part has information that helps with making the best possible Gaussian Splat).
TODO: Replace this video with a Resonite specific Tutorial for Gaussian Splats.
There is the Gaussian Splat Tool (That uses the GaussianSplatTool component), used for manipulating the shape of the Gaussian Splat itself.
Technical Details
Gaussian Splats take full advantage of Spherical Harmonics to apply color and lighting data when rendering into the world.
Examples
- There is a world dedicated to Guassian Splats called A_world_you_can't_see._yet....
