WasmGPU.math.vec3.copy

Summary

WasmGPU.math.vec3.copy clones the input into a new array. Use it when you want an explicit copy before further edits.

Syntax

WasmGPU.math.vec3.copy(v: number[]): number[]
const result = wgpu.math.vec3.copy(v);

Precision-Specific Wasm Forms

WasmGPU.math.vec3f.copy(out: WasmPtr, v: WasmPtr): void
WasmGPU.math.vec3d.copy(out: WasmPtr, v: WasmPtr): void

These forms use caller-owned pointers to 3-element vector blocks in WasmGPU driver memory: binary32 for vec3f and binary64 for vec3d. 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
v number[] Yes Vector input as [x, y, z].

Returns

number[] - New 3D vector as [x, y, z].

Type Details

type Vec3 = number[]; // expected length: 3 ([x, y, z])

Example

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

const v = [1, 2, 3];
const result = wgpu.math.vec3.copy(v);
console.log(result);
