Camera.lookAtWithUp¶
Summary¶
Camera.lookAtWithUp rotates the camera toward a target while honoring an explicit up direction. This is useful when working with non-default axis conventions or avoiding roll ambiguity in specialized views. The method includes a fallback when target and up become nearly collinear.
Syntax¶
Camera.lookAtWithUp(target: readonly number[], up: readonly number[]): Camera
const result = camera.lookAtWithUp(target, up);
Parameters¶
| Name | Type | Required | Description |
|---|---|---|---|
target |
readonly number[] |
Yes | World-space point the camera should face. |
up |
readonly number[] |
Yes | Preferred world-space up vector for orientation construction. |
Returns¶
Camera - The same camera instance, allowing chained camera operations.
Type Details¶
Example¶
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);
const camera = wgpu.createCamera.perspective({ aspect: canvas.clientWidth / canvas.clientHeight });
camera.transform.setPosition(2, 2, 2);
camera.lookAtWithUp([0, 0, 0], [0, 0, 1]);
const scene = wgpu.createScene();
wgpu.render(scene, camera);
