Function useFiveProject2d

useFiveProject2d(): ((vector: Vector3, testModel: boolean) => Vector2)

Five React Hooks: 将三维的坐标对应到而为屏幕

Returns ((vector: Vector3, testModel: boolean) => Vector2)

- (vector, testModel): Vector2
- Parameters
  - vector: Vector3
  - testModel: boolean
  Returns Vector2

Function

preject2d

计算模型射线碰撞检测
// 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
preject2d(vector: THREE.Vector3, testModel: boolean): THREE.Vector2 ｜ null

Example

const preject2d = useFiveProject2d();
const { x: width, y: height } = preject2d(new THREE.Vector3(0, 0, 0));
