Ray::Intersects (plane)

bool Intersects(const Plane& plane, float& t) const

检测射线是否与平面相交。

参数:

  • plane - 要检测的平面
  • t - 输出交点的参数距离

返回: bool - 相交返回 true射线朝向平面否则返回 false

复杂度: O(1)

示例:

Ray ray(cameraPosition, rayDirection);
Plane groundPlane = Plane::FromNormalAndPoint(Vector3::Up(), Vector3::Zero());
float t;
if (ray.Intersects(groundPlane, t)) {
    Vector3 hitPoint = ray.GetPoint(t);
    // 射线命中地面
}
