# GlyphField.mapLinearIndexToNd

## Summary
GlyphField.mapLinearIndexToNd maps values between indexing/representation schemes used by this GlyphField.

## Syntax
```ts
GlyphField.mapLinearIndexToNd(index: number): number[] | null
const result = glyphField.mapLinearIndexToNd(index);
```

## Parameters
| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `index` | `number` | Yes | Linear element index into CPU-backed arrays. |

## Returns
`number[] | null` - Result produced by this API call as `number[] | null`.

## Type Details
```ts
// No additional descriptor expansion is required for this signature.
```

## Example
```js
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const glyphField = wgpu.createGlyphField({ instanceCount: 1, positions: new Float32Array([0, 0, 0, 0]), rotations: new Float32Array([0, 0, 0, 1]), scales: new Float32Array([1, 1, 1, 0]), attributes: new Float32Array([0.5, 0, 0, 0]), scaleTransform: { mode: "linear", domainMin: 0, domainMax: 1 } });
const index = 0;
const result = glyphField.mapLinearIndexToNd(index);
console.log(result);
```
