Enum RtDynamicMode 

pub enum RtDynamicMode {
    Off,
    Auto,
    Rebuild,
    Tlas,
}

How the scene acceleration structure is kept current when props move. Selected once at init from the launch’s --rt-dynamic request; Auto is the shipping behaviour and what an unset request resolves to.

Variants

Off

Build once, never update. Forces a static BVH even if props move: the pre-dynamic behaviour, kept as a fast path / diagnostic (off).

Auto

Default. Rebuild the TLAS + table (fresh allocations, static BLAS) only on the frames a participating transform actually changed. Static scenes never rebuild, so they pay only a cheap per-frame matrix compare.

Rebuild

Force a full BVH rebuild every frame, dirty or not. Diagnostic (rebuild); the most expensive path.

Tlas

Force a fresh TLAS + table rebuild every frame, dirty or not. Diagnostic (tlas); the same GPU work Auto does, minus the dirty gate.

Implementations
