How to identify list of Objects in Camera view

Questions & Answers
1

Hi,

I am using GeometryUtility.CalculateFrustumPlanes and GeometryUtility.TestPlanesAABB

to see if an object is seen by my camera or not. I also use Physics.Raycast
to make sure that nothing is covering the object.

However, I want to know what are the game objects that can be ‘seen’ from the camera without telling the camera what object it could be seeing.

In other words, when I use TestPlanesAABB
I do NOT want to test against a specific game object. I want it to be unknown and then when the camera ‘sees’ some object, I need to know what is this object.

Any help?!

One way or another, you have to check a list of objects. You can distribute that check so that objects check themselves rather than a central check. If you only have one camera there are a number of things you can do to simplify your code. For example, you can use Renderer.OnBecameVisible() and Renderer.OnBecomeInvisible() in each game object.
