WasmGPU.math.mat4.identity

WasmGPU.math.mat4.identity¶

Summary¶

WasmGPU.math.mat4.identity creates an identity matrix. This is the standard neutral element for matrix multiplication.

Syntax¶

WasmGPU.math.mat4.identity(): number[]
const result = wgpu.math.mat4.identity();

Precision-Specific Wasm Forms¶

WasmGPU.math.mat4f.identity(out: WasmPtr): void
WasmGPU.math.mat4d.identity(out: WasmPtr): 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¶

This function does not take parameters.

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 result = wgpu.math.mat4.identity();
console.log(result);
