Syntax

WasmGPU.math.mat4.isIdentity(matr: number[]): boolean
const result = wgpu.math.mat4.isIdentity(matr);

Parameters

Name Type Required Description
matr number[] Yes Input 4x4 matrix (16 numbers in column-major order) used by this operation.

Returns

boolean - Boolean flag indicating whether the tested condition is satisfied.

Type Details

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

Example

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

const matr = wgpu.math.mat4.translate(wgpu.math.mat4.identity(), [1, 2, 3]);
const result = wgpu.math.mat4.isIdentity(matr);
console.log(result);
