# PPISP on a Real 3-Camera Capture — OFF vs ON

An interactive drag-to-compare of **NVIDIA's PPISP** run inside Forenly AI's
**Scene→Sim** pipeline. Same capture, same 30k iterations, one toggle:

- **OFF** → the reconstruction collapses into a hazy, washed-out blur
- **ON** → sharp, colour-correct and stable (**+9.5 dB PSNR**)

PPISP fixes the photometric artifacts that wreck radiance-field and Gaussian-splatting
reconstructions. In our Scene→Sim pipeline we turn real multi-camera captures into
simulation-ready 3D scenes where humanoid robots learn their skills — so every dB of
reconstruction fidelity is a better training ground.

Methods benchmarked in this line of work: **PPISP · 3DGRUT · 2DGS · GOF**.
