# GlyphField.upload

## Summary
GlyphField.upload uploads pending CPU/wasm data into GPU buffers so this GlyphField is render-ready.

## Syntax
```ts
GlyphField.upload(device: GPUDevice, queue: GPUQueue): void
glyphField.upload(device, queue);
```

## Parameters
| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `device` | `GPUDevice` | Yes | GPUDevice used to allocate pipelines, buffers, layouts, or textures. |
| `queue` | `GPUQueue` | Yes | GPUQueue used for data uploads and command submissions. |

## Returns
`void` - No return value. The call applies side effects to runtime state and/or GPU resources.

## 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 device = wgpu.gpu.device;
const queue = wgpu.gpu.queue;
glyphField.upload(device, queue);
console.log("updated");
```
