## What it is
SplatTransform is an open-source CLI tool and library for converting, editing, and optimizing 3D Gaussian splat files. It supports reading and writing many splat formats (PLY, SOG, SPZ, SPLAT, KSPLAT, LCC, GLB, and more) and offers transformations, merging, filtering, LOD generation, and statistical analysis.

## Use cases
- convert ply gaussian splat to sog or spz format
- merge multiple 3d gaussian splat files into one
- compress gaussian splat for web streaming
- generate lod streamed sog from a single ply
- filter out spherical harmonic bands from a splat
- generate collision mesh from a splat scene
- apply transforms to gaussian splat point clouds
- view gaussian splat in browser as html viewer

## When to choose
- you need to convert between many 3DGS formats in a pipeline or CI
- you want to optimize, merge, or filter splats from the command line
- you need a Node.js or browser library for programmatic splat processing
- you want LOD streaming assets for web rendering with PlayCanvas

## When to avoid
- you need a visual editor for splats (use SuperSplat instead)
- you need to capture or train Gaussian splats from photos (this only processes existing splats)
- you work with traditional mesh or point-cloud formats unrelated to 3DGS
