Function useFiveProject2d

useFiveProject2d(): Project2d

Five Vue Hooks: 计算三维坐标对应到屏幕二维坐标

Returns Project2d

Function

project2d

计算三维坐标对应到屏幕二维坐标
`useFiveProject2d()` 通过 watch 监听入参和 cameraUpdate 变化，自动更新返回值
多次调用时会创建多个 watch 监听，推荐 const { project2d } = useFiveAction();
// param vector 三维的坐标
// param testModel 是否和模型检测，如果检测，则被模型遮挡会返回 null
// returns 三维的坐标 或者 null
project2d(vector: THREE.Vector3 | Ref<THREE.Vector3>, testModel: boolean)
v2: Ref<THREE.Vector2 | null>

Example

const project2d  = useFiveProject2d();
project2d(new THREE.Vector3(0, 0, 0));
