Interface Phase0RendererOptions

Clip-space depth added to every batch reconciled as representation: "coarse", as a fraction of the depth range. Coarse proxies are prototype bounding boxes, so their faces coincide with the target surfaces of other objects (slab tops, floor layers, window plates) and z-fight them until that detail arrives; pushing proxies back by a fixed offset lets resident detail win the depth test. Zero disables the fallback pipelines. Defaults to defaultFallbackDepthOffset.

Override the browser device pixel ratio for reproducible benchmark profiles.

Request the WebGPU "timestamp-query" feature when the adapter exposes it. Render passes may then receive caller-owned timestamp writes. Devices without the feature are still created; passing timestamp writes to render() on such a device raises a typed error.
