I want to create an interface that allows a pointing and selecting with mouse. The problem is that i don't know what is the best method.

My idea is :
Trace a 3d line (not visible) starting from the mouse 2d coordinates and normal to camera view. So i find the first object intersected.
(and of course, i don't yet understand how i have to implement my idea).

Other ideas ???

You can now use the pick object() command with patch 5 - see the example under "Basic 3D examples" in the help file.

There's no place like 127.0.0.1

There are 10 people in this world, those who understand binary and those who don't.

David89, do u understand binary, because the number in your name has 4 possible combinations and not 2

10 in decimal is 2 Binary is nothing about combinations:

-First row on right is 1s
-Second row from right is 2s
-Third is 4s

therefore:

1 0 = one 2 and zero 1s = 2

Do you understand binary?

lol - I understood it Then again, i'm one of the 10b types of people on this world.

As for selecting an object there are new commands, or if you are using the previous version of DB or dont like the new commands you can always use object screen x/y() and compare that to the mouse pointers position.
