Check if mesh is in Frustum and not hidden by other meshes?


Recommended Posts

Is there a simple way to check if a mesh is in the frustum and not hidden by other meshes? It seems pretty easy to check if the camera is aimed at the mesh in general:


But I want to check if the mesh is not hidden by other meshes. I'm creating a 3-D maze and need to move/lock the camera temporarily when certain objects hidden in the maze come into view.

If I have to, I can determine a geometric area where if the free camera is in that area and the mesh is active it is visible, but I'd prefer to do it an easier / better way if possible.

Hi and Welcome !
Yeah, there are two methods (https://doc.babylonjs.com/api/classes/babylon.camera#isinfrustum) and (https://doc.babylonjs.com/api/classes/babylon.camera#iscompletelyinfrustum) you'll find them in Mesh/Camera class,  Regarding determining the geometric area you can use this as reference - https://www.babylonjs-playground.com/#1BDA0J#0
