3D Gaussian Splatting with Unity VFX Graph
SplatVFX is an experimental implementation of 3D Gaussian Splatting with Unity VFX Graph.
No. I made many compromises to implement it with VFX Graph. I recommend trying other solutions like UnityGaussianSplatting.
.splat file (bicycle.splat) and put it in the
URP/Assets directory.URP/Assets/Test.unity and start Play Mode..splat file..splat is an ad-hoc file format used in antimatter15's
WebGL Gaussian Splat Viewer. You can convert a .ply file into .splat by
dragging and dropping it into a viewer window.
The default VFX Graph (Splat.vfx) supports up to 8 million points. You must
increase the capacity when your .splat file has more points. Duplicate
Splat.vfx into your project and edit it to change the capacity value in the
Initialize Particle context.
You can check how many points are in a .splat file on Inspector.
Typically, .splat files are trained with the reference rasterizer running
on the sRGB color space. It causes artifacts when using the Linear Lighting
Mode in Unity. You can remedy it by grading in post-processing, but it's
impossible to get perfect results with manual tweaks.
The Gaussian projection algorithm used in the VFX Graph is far from perfect. It causes many artifacts, including sudden pops with camera motion.
