Overview¶

Represents a data type that can be serialized/deserialized to/from a binary form, both in TypeScript and in WGSL.

Type BinaryOp¶

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

• name: string
• type: ConcreteType<T>
• isCommutative: boolean
• identity: T
  TS
• apply: ( a: T, b: T ) => T
• identityWGSL: WGSLExpressionT
  WGSL
• combineExpression?: ( a: WGSLExpressionT, b: WGSLExpressionT ) => WGSLExpressionT
• combineStatements?: ( varName: WGSLVariableName, a: WGSLExpressionT, b: WGSLExpressionT ) => WGSLStatements
  TODO: Don't have this, if needed just rely on a function placed on the blueprint(!) TODO: remove this(!)
• atomicName?: string

Type BitOrder¶

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

• name: string
• type: ConcreteType<T>
• getBits: ( value: T, bitOffset: number, bitQuantity: number ) => number
  TS
• getBitsWGSL: ( value: WGSLExpressionT, bitOffset: number, bitQuantity: number ) => WGSLExpressionU32
  WGSL

Type CompareOrder¶

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

• name: string
• type: ConcreteType<T>
• compare: ( a: T, b: T ) => number
  TS
• compareWGSL: ( a: WGSLExpressionT, b: WGSLExpressionT ) => WGSLExpressionI32
  WGSL
• greaterThanWGSL: ( a: WGSLExpressionT, b: WGSLExpressionT ) => WGSLExpressionBool
• lessThanOrEqualWGSL: ( a: WGSLExpressionT, b: WGSLExpressionT ) => WGSLExpressionBool

Type ConcreteArrayType¶

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

ConcreteType<T[]> & { elementType: ConcreteType<T>; length: number }

Type ConcreteType¶

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

• name: string
• bytesPerElement: number
  TODO: deduplicate with wgslSize/wgslAlign. This is the size of the ENTIRE type, drop the "element" bit
• outOfRangeElement?: T
• equals: ( a: T, b: T ) => boolean
  TS
• equalsWGSL: ( a: WGSLExpressionT, b: WGSLExpressionT ) => WGSLExpressionBool
  WGSL
• valueType: WGSLType
  WGSL representation TODO: consider rename to valueTypeWGSL?
• wgslAlign: number
  See https://www.w3.org/TR/WGSL/#alignment-and-size
• wgslSize: number

Type Order¶

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

BitOrder<T> & CompareOrder<T>

Type StoreStatementCallback¶

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

( offset: WGSLExpressionU32, u32expr: WGSLExpressionU32 ) => WGSLStatements

Type WGSLBinaryStatements¶

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

( value: WGSLVariableName, a: WGSLExpression, b: WGSLExpression ) => WGSLStatements
