Class WgpuGeometryCache

Whether WgpuGeometryCache.dispose has run.

Number of geometries currently uploaded. Diagnostics and tests (§83).

Returns the buffers for geometry, uploading them on first use and re-uploading whenever geometry.version has advanced.

normals says whether the draw at hand shades (WP-R1.5): true uploads the geometry's normal stream — with the initial upload, or as a one-buffer upgrade of a record first acquired by an unshaded draw — and false (the default, and every pre-WP-R1.5 call site verbatim) never touches it, so a scene with no lit materials records the byte-identical upload sequence it always did. skinning is the same flag for §54's joints and weights (RFC 0003): true uploads them on a skinned colour draw, false (the default, every pre-skinning call site verbatim) never touches them, so a skinless scene — and an unregistered skinned skip, which never asks — records the byte-identical upload sequence it always did. See the module header for why the flags are per acquisition.

Returns null — and creates no entry — when there is nothing to draw (drawCount === 0, which includes every disposed geometry) or once the cache is disposed. Never throws: this runs inside Renderer.render, and §61 forbids throwing there.

Destroys every allocation and marks the cache disposed (§83). Idempotent.

Drops every record without destroying anything — the device-loss path (§61). The allocations belong to a device that no longer exists; calling destroy() on them would be a call against a lost device for no benefit.
