[Closed] how to get "region of viewport" input from user

Oct 11, 2010 7:33 pm

I need to get an input for “region of viewport” input from user.
Something like region selection.
User uses rectangle to define region and I need to get box2 value of that region.

What would be the most efficient way?

using a scripted mouse tool maybe for example :

(
	global pA
	global pB
	tool boxDrag
	(		
		on mousepoint clickNumber do
		(
			if clickNumber == 1 then
				pA = viewpoint
			else
				#stop
		)
		on mousemove clickNumber do(
			pB = viewpoint			
		)
	)
	starttool boxDrag
	select (boxpicknode (box2 pA pB))
)

cheers!
