Interface ProgressiveSpec

Number of per-source-object createObject calls between yields. Default 50 — roughly one frame per yield on a typical BIM model with HLE on. Smaller values give finer progressive painting at the cost of more yield overhead.

Custom yield function — called between batches. Defaults to a requestAnimationFrame-backed promise (or setTimeout(0) outside the browser). Pass your own to pace yields against a scheduler (e.g. requestIdleCallback) or to forward through an instrumentation hook.
