Splat Toolkit
A 3D Gaussian splat file is a long list of soft colored blobs, each with a place, a size in three directions, a turn, an opacity and a color (sometimes a color that changes with the viewing angle, called spherical harmonics).

About it
A 3D Gaussian splat file is a long list of soft colored blobs, each with a place, a size in three directions, a turn, an opacity and a color (sometimes a color that changes with the viewing angle, called spherical harmonics). This toolkit opens the common formats (PLY, compressed PLY, .splat, SPZ and SOG) and shows what is inside: how many splats, how big the scene is, the harmonics' degree, and the memory it takes.
Crop keeps what is inside a box. Remove floaters finds the stray blobs a capture leaves in the air: for each splat it measures the average distance to its nearest neighbors, and those much farther out than the rest (a statistical outlier filter) are removed; show them in red, or before and after side by side. Shrink keeps the splats that show most. Save writes the result in the format you choose, and Compare puts a second splat beside the first, turning in step. Everything runs on your device in the background; nothing is uploaded.
