Type mainReduceWGSLOptions¶

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

• input: BufferSlot<T[]>
• output: BufferSlot<T[]>
• binaryOp: BinaryOp<T>
  TODO: should we really have lengthExpression in loadReducedOptions? Also inputOrder options?!?
• stripeOutput?: boolean
  We can stripe the output (so the next layer of reduce can read it as striped)
• convergentRemap?: boolean
  Whether we should remap the data to convergent indices before reducing (i.e. a convergent reduce with non-commutative data.
• loadReducedOptions?: StrictOmit<loadReducedWGSLOptions<T>, "value" | "binaryOp" | "loadExpression" | "loadStatements" | "workgroupSize" | "grainSize" | "globalIndex" | "workgroupIndex" | "localIndex">
  e.g. lengthExpression / inputOrder / inputAccessOrder / sequentialReduceStyle
• reduceOptions?: StrictOmit<reduceWGSLOptions<T>, "value" | "scratch" | "workgroupSize" | "binaryOp" | "localIndex" | "scratchPreloaded" | "valuePreloaded" | "mapScratchIndex">
  e.g. convergent
