math.quat.random¶
Summary¶
math.quat.random creates a new quaternion whose four components are sampled independently from the provided numeric range. The result is not normalized automatically, so normalize it before using it as a rotation when unit length is required.
Syntax¶
WasmGPU.math.quat.random(min: number, max: number): number[]
const result = wgpu.math.quat.random(min, max);
Precision-Specific Wasm Forms¶
WasmGPU.math.quatf.random(out: WasmPtr): void
WasmGPU.math.quatd.random(out: WasmPtr): void
WasmGPU.math.quatf.randomRange(out: WasmPtr, min: number, max: number): void
WasmGPU.math.quatd.randomRange(out: WasmPtr, min: number, max: number): void
These forms use caller-owned pointers to 4-element quaternion blocks in WasmGPU driver memory: binary32 for quatf and binary64 for quatd. 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 quaternion as [x, y, z, w].
Type Details¶
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const min = -1.0;
const max = 1.0;
const result = wgpu.math.quat.random(min, max);
console.log(result);
