 ## Overview
 
-Gaussian splats are currently stored in mostly unstructured files. This extension is an attempt to bring them to glTF and offer a structured, efficient method for streaming and rendering them.

-This method uses textures to store data for efficient GPU loading.
+Gaussian splats are currently stored in mostly unstructured files such as PLY. This aims to bring that format into glTF in a simple and straightfoward way.
 
-Data formats within textures:
- * Positions (R10G10B10A2 good default),
- * Rotations (always R10G10B10A2),
- * Scales (R5G6B5 good default),
- * Color+opacity (R8G8B8A8 is easy),

 ## Implementation Notes
 
-This doesn't specify any specific rendering techniques. This is purely for organizing the data in a structured manner.
