WasmGPU.createTransform().setRotationFromAxisAngle¶
Summary¶
WasmGPU.createTransform().setRotationFromAxisAngle sets local orientation from an axis-angle pair. The axis vector is normalized internally, then converted into a quaternion. Use this when rotation is naturally expressed around a known direction (for example spin around Y axis). The angle is specified in radians.
Syntax¶
WasmGPU.createTransform().setRotationFromAxisAngle(axis: number[], angle: number): this
const result = transform.setRotationFromAxisAngle(axis, angle);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
axis |
number[] |
Yes | Rotation axis as three numeric components; it is normalized internally. |
angle |
number |
Yes | Rotation angle in radians around axis. |
Returns¶
this - Returns the same transform after setting orientation.
Type Details¶
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const spinner = wgpu.createTransform();
const axis = [0, 1, 0];
spinner.setRotationFromAxisAngle(axis, Math.PI / 3);
console.log(spinner.rotation);
