# Geometry.upload

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

## Syntax
```ts
Geometry.upload(device: GPUDevice): void
geometry.upload(device);
```

## Parameters
| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `device` | `GPUDevice` | Yes | GPUDevice used to allocate pipelines, buffers, layouts, or textures. |

## 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 geometry = wgpu.geometry.sphere(1, 24, 16);
const device = wgpu.gpu.device;
geometry.upload(device);
console.log("updated");
```
