# Guided Multiview Ray Tracing for Fast Auralization

## One-sentence takeaway

Guided multiview ray tracing: trace from both source and listener with importance/visibility guidance so auralization rays hit.

## Why it matters here

Naïve Monte Carlo auralization wastes rays in occluded rooms. Taylor/Chandak/Manocha 2012 TVCG is the guided/multiview geometric tracer before full BDPT 2016. Useful if Anoptic already has vis maps from graphics.

## Key ideas

- **Multiview.** Sample from source *and* listener, not a single camera analog.
- **Guiding.** Bias rays toward mutually visible / high-throughput regions.
- **IEEE TVCG 2012.** Interactive auralization framing.
- **GAMMA stack.** RESound 2009 → guided 2012 → BDPT 2016.

## Caveats

Geometric MC; variance remains. Not wave. Guidance from a stale vis map will miss dynamic portals.
