Adam Morris 133b04b811 Updated the 3DGS code to support the latest spec and deprecated old spec 2025-08-26 13:00:14 -05:00
keyboardspecialist 371e8cc469 updated spz-loader to 0.3.0, this brings SPZ 2.0.0 support 
Rectifies some issues with orientation as the old spz-loader forced a rotation around the X axis. Related PrimitiveLoadPlan code removed, no longer needed.

keyboardspecialist d684417bb8 Gaussian Splat Texture Generator now uses TaskProcessor. Async creation moved to Model from PrimitiveLoadPlan (where is was synchronous).. 
Reworked logic in runtime primitive. No longer auto fallback to other pipeline.

Jason Sobotka b2f5aa2fc7 Lots of pipeline changes. 
Sorting no longer occurs during the Gaussian texture pipeline.

Texture path shaders simplified and optimized. (Should migrate if attribute pipeline stays).

Migrating to proper task processor workers for sorting and texture generation

Lots of clean up.
