Apples, not oranges. This isn't for 3d models and scenes- think of it as a fancy version of streetview or an apartment walkthrough. Those project pictures onto a sphere around you. Gaussian splats are an improvement that uses multiple images to interpolate viewpoints- take two pictures from different angles, and guassian splats let you take a look from between those views, or above or below them.

This method uses ai to generate even more unseen structure, so with relatively few images you can still represent a real scene with some level of fidelity. It will never need dynamic lights or animation because the point is just to look as close as possible to a still image. Splats do that FAR better and more efficiently than you ever could with dynamic lighting, triangulated models, and visual effects.
