how can i get objects size according to world coordinate?

I want to draw number of objects in half of screen in rows and columns. But i don’t want those drawn in next half of screen so i have to find out that if my object is being drawn on next half of screen or not.

Thanks.

Assuming your camera is axes aligned, you can use Renderer.bounds.

From the reference: Using bounds is convenient to make rough approximations about the object’s location and its extents.

If your camera is not axes aligned, then things get more complicated.
