histogramWGSL¶

Under Construction

This documentation is auto-generated, and is a work in progress. Please see the source code at https://github.com/phetsims/alpenglow/blob/main/js/webgpu/wgsl/gpu/histogramWGSL.ts for the most up-to-date information.

Overview¶

Calculates a histogram in shared (workgroup) memory by using atomics

import type { histogramWGSLOptions } from 'scenerystack/alpenglow';

histogramScratch: WGSLVariableName
var<workgroup> array<atomic<u32>, numBins> // TODO: can we actually get memory-compacted histograms here, instead of using a full u32?
getBin: ( index: WGSLExpressionU32 ) => WGSLExpressionU32
& StrictOmit<coalescedLoopWGSLOptions, "callback">
