Optimization-Free Style Transfer for 3D Gaussian Splats
Authors: name: Raphael Du Sablon, name: David Hart

The task of style transfer for 3D Gaussian splats has been explored in many
previous works, but these require reconstructing or fine-tuning the splat while
incorporating style information or optimizing a feature extraction network on
the splat representation. We propose a reconstruction- and optimization-free
approach to stylizing 3D Gaussian splats. This is done by generating a graph
structure across the implicit surface of the splat representation. A
feed-forward, surface-based stylization method is then used and interpolated
back to the individual splats in the scene. This allows for any style image and
3D Gaussian splat to be used without any additional training or optimization.
This also allows for fast stylization of splats, achieving speeds under 2
minutes even on consumer-grade hardware. We demonstrate the quality results
this approach achieves and compare to other 3D Gaussian splat style transfer
methods. Code is publicly available at
