How to determine a plane vertical or horizontal in ARcore?

As title, I want to determine a plane is vertical or horizontal in ARcore in run-time. How should I do this?

Solution

  • From ARCore Plane.Type docs:

    Plane.Type t = yourPlane.getType();

if(t == Plane.Type.VERTICAL)
  // Vertical plane
else if(t == Plane.Type.Plane.Type HORIZONTAL_DOWNWARD_FACING)
  // Ceiling, camera looking up at
else if(t == Plane.Type.Plane.Type HORIZONTAL_DOWNWARD_FACING)
  // Floor, ground, camera looking down at
