Another experiment with Gaussian Painters ✨🎨 By optimizing 3D Gaussian Splattings over separate images at several viewpoints, it is possible to get a Steganography effect! Three paintings are hidden in those gaussian splats

Are you disabling view-dependent effects? This idea is most compelling when the radiance is Lambertian.

Yes, was setting sh_degree to 0 for most experiments. For this one, seems I enabled them, but I agree! Otherwise, it could converge to just a plane of spheres at each pixel with SH coefficients

This is a flagrant misuse of the technology and it’s f’ing awesome.

Very cool! Quick tip: there's a viewing option other than Trackball called "Interpolate". It might just do exactly what you want for this.

Ah wow thanks a lot! And thanks for making 3DGS!

Woah I think this is actually made me grasp how Gaussian Splatting works a lot more, what a great example!

So can we have a space where rotating along one axis gives different frames of a video.

Yes sure this is exactly how the Horse in Motion was first creating a video effect

this experiment in particular is really cool, can’t wait to try it!
