WebGPUTimestampQueryPool
Manages a pool of WebGPU timestamp queries for performance measurement. Extends the base TimestampQueryPool to provide WebGPU-specific implementation.
Constructor
new WebGPUTimestampQueryPool( device : GPUDevice, type : string, maxQueries : number )
Creates a new WebGPU timestamp query pool.
device
The WebGPU device to create queries on.
type
The type identifier for this query pool.
maxQueries
Maximum number of queries this pool can hold.
Default is 2048.
Methods
.allocateQueriesForContext( uid : string ) : number
Allocates a pair of queries for a given render context.
uid
A unique identifier for the render context.
Overrides: TimestampQueryPool#allocateQueriesForContext
Returns: The base offset for the allocated queries, or null if allocation failed.
.dispose() : Promise (async)
Dispose of the query pool.
Overrides: TimestampQueryPool#dispose
Returns: A Promise that resolves when the dispose has been executed.
.resolveQueriesAsync() : Promise. (async)
Asynchronously resolves all pending queries and returns the total duration. If there's already a pending resolve operation, returns that promise instead.
Overrides: TimestampQueryPool#resolveQueriesAsync
Returns: The total duration in milliseconds, or the last valid value if resolution fails.
