Hidding a Group2D whend the tracked mesh is off-screen
thomasc posted a topic in Questions & Answers
Hello, Group2D on a canvas is really a powerfull tool to add labels / tooltips on 3D object But apparently Group2D are being displayed even when the mesh is off-screen or, more precisely, behind the camera. This playground shows this beahiour (it is the tracking boxes demo with the camera radius set so that the camera is positionned in the middle of the boxes) : http://babylonjs-playground.com/#1N9RJY#34 As you can see labels are displayed for boxes located behind the camera as well. Is there a way to hide them easily ? I imagine that Group2D is projecting the central point on the tracked mesh on the screen, without checking if the mesh is in front or behind the screen plane. Thanks
