WasmGPU.math.quat.normscl¶
Summary¶
WasmGPU.math.quat.normscl normalizes the input and then applies a scalar magnitude. Use it when you need a direction with a prescribed length.
Syntax¶
WasmGPU.math.quat.normscl(q: number[], scalar: number): number[]
const result = wgpu.math.quat.normscl(q, scalar);
Precision-Specific Wasm Forms¶
WasmGPU.math.quatf.normscl(out: WasmPtr, q: WasmPtr, scalar: number): void
WasmGPU.math.quatd.normscl(out: WasmPtr, q: WasmPtr, scalar: 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 |
|---|---|---|---|
q |
number[] |
Yes | Quaternion input as [x, y, z, w]. |
scalar |
number |
Yes | Scalar factor used to uniformly scale components. |
Returns¶
number[] - New quaternion as [x, y, z, w].
Type Details¶
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const q = [0, Math.sin(Math.PI / 8), 0, Math.cos(Math.PI / 8)];
const scalar = 0.5;
const result = wgpu.math.quat.normscl(q, scalar);
console.log(result);
