WasmGPU.math.mat4.random

Summary

WasmGPU.math.mat4.random generates a random value within the provided numeric range. Use it to synthesize test data or randomized initialization.

Syntax

WasmGPU.math.mat4.random(min: number, max: number): number[]
const result = wgpu.math.mat4.random(min, max);

Precision-Specific Wasm Forms

WasmGPU.math.mat4f.random(out: WasmPtr): void
WasmGPU.math.mat4d.random(out: WasmPtr): void
WasmGPU.math.mat4f.randomRange(out: WasmPtr, min: number, max: number): void
WasmGPU.math.mat4d.randomRange(out: WasmPtr, min: number, max: number): void

These forms use caller-owned pointers to 16-element matrix blocks in WasmGPU driver memory: binary32 for mat4f and binary64 for mat4d. Methods with an output pointer write that block instead of allocating a JavaScript array. See WasmGPU.math for allocation, views, aliasing, and release requirements.

Parameters

Name Type Required Description
min number Yes Minimum random bound (inclusive lower bound).
max number Yes Maximum random bound (inclusive upper bound); should be >= min.

Returns

number[] - New 4x4 matrix as a 16-number column-major array.

Type Details

type Mat4 = number[]; // expected length: 16 (4x4, column-major)

Example

const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const min = -1.0;
const max = 1.0;
const result = wgpu.math.mat4.random(min, max);
console.log(result);
