GlyphField.setBuffers¶
Summary¶
GlyphField.setBuffers updates buffers state on this GlyphField and marks dependent GPU data for refresh.
Syntax¶
GlyphField.setBuffers(positions: GPUBuffer, rotations: GPUBuffer, scales: GPUBuffer, attributes: GPUBuffer | null, instanceCount: number): void
glyphField.setBuffers(positions, rotations, scales, attributes, instanceCount);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
positions |
GPUBuffer |
Yes | Packed per-instance positions. |
rotations |
GPUBuffer |
Yes | Packed per-instance quaternion rotations. |
scales |
GPUBuffer |
Yes | Packed per-instance scales. |
attributes |
GPUBuffer \| null |
Yes | Packed per-instance attribute values. |
instanceCount |
number |
Yes | Number of instances represented by supplied data inputs. |
Returns¶
void - No return value. The call applies side effects to runtime state and/or GPU resources.
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 positions = new Float32Array([0, 0, 0, 0]);
const rotations = new Float32Array([0, 0, 0, 1]);
const scales = new Float32Array([1, 1, 1, 0]);
const attributes = new Float32Array([0.5, 0, 0, 0]);
const instanceCount = 1;
glyphField.setBuffers(positions, rotations, scales, attributes, instanceCount);
console.log("updated");
