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. |

Type Details¶
Example¶
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");
