WasmGPU.math.mat4.round

Summary

WasmGPU.math.mat4.round rounds each component to the nearest integer. It is useful when snapping values to a grid or discrete representation.

Syntax

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

Precision-Specific Wasm Forms

WasmGPU.math.mat4f.round(out: WasmPtr, m: WasmPtr): void
WasmGPU.math.mat4d.round(out: WasmPtr, m: 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

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

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