Visible objetcs

How I capture the visible objects (triangles, vertex) in the scene after clipping,

I think you have to try and explain again what it is exactly that you want to do… Maybe it's the fact that I dont speak English as my first language… but I did not quite get it  :slight_smile:

Most importantly what do you mean by 'capture'?

object identification (object-visibility list) in the screen and the object's visible part.

There's a method in the camera class, "contains" which checks if an object is inside the frustum or not.

I need since only the active object visible in the screen to compute the object-visibility list (objects or  the object's visible part are inside line sight), different to checks if an object is inside the frustum (object visible and objects are completely hidden).
