How to prevent repackaging?

Question

This is a tricky question to search on Google, because it has a different meaning in finance.

Of course, I mean here "Drawing", as in .. computer graphics .. not money ..

I am interested in preventing forwarding for both a 3D drawing and a 2D drawing.
(should I make them to two different questions?)

I understand that this can be a very broad question, since I did not indicate which technology to use. If it is too wide, perhaps some hints of some resources that I can read will be fine.

EDIT:
What I mean when overloaded is:

• when you draw too many objects, rendering a single frame will be very slow.
• when you draw more area than necessary, rendering one frame will be very slow.

Answer 1

This is a rather complicated topic.

The first thing to consider is trimming removal . It will filter out objects that are not in the field of view of the cameras, so you can simply transfer them at the rendering stage.
