Example
This example uses the World To Screen node to get the projected screen coordinate of a hand. It then uses the Vertex to Rect node to construct a rectangle collider for the 2D image. Lastly, it uses the point in the Box node to detect if the hand center’s screen coordinates collide with the image. It uses the collision detection result to toggle the visibility of the sphere.
