- [Instructor] Here I want to discuss the compass.
As you can see, the compass is currently
nested on its, what's called perch.
The compass is a very large subject of discussion.
And I'm going to keep it brief,
but I need you to understand a certain key few elements
to the compass, so that when you look at it,
you understand what the compass is telling you.
As I talked about briefly before,
you can adjust and manipulate your graphics window
using the compass by using your first mouse button,
grabbing one of the arms, or vectors
on that compass, to adjust the screen.
You can also grab one of the planes.
Again, just holding down your first mouse button
you can see I can pan based off of that plane.
Now currently, as the compass sits on its perch,
you're going to notice the X, Y, Z are oriented
to absolute X, Y, Z.
With this little red block at the very bottom
of the compass, if I grab that and drag the compass down
and drop it on to one of the parts somewhere in the screen,
you'll notice the orientation of the compass changes.
By releasing the mouse button now,
what I want you to notice is
they X, Y, Z are no longer singular X, Y, Z.
You have your ux, vz,
and in this case, w.
What's going on is the compass is now oriented
to its current position and it is no longer
oriented to absolute.
By moving the compass away from its perch,
and dropping it on its part,
it signifies the difference in orientation
by changing the lettering of the compass.
If I double click on the compass,
you'll notice that I have coordinates.
You're able to move the compass around
based off of its current position to absolute
and within increments.
Again, these are advanced functionalities.
We'll be talking about some of these things
in the product level of this course.
But some of the things that are here
are beyond the scope, so we'll discuss these
at a different time.
Now, I'll just simply close.
If at this point I want to return the compass
to perch and I just simply grab it
and just drag it and drop it off in space.
What I want you to notice is that
it's still at its current orientation.
I have my w, my u and my v.
If I want to turn the compass to it's true,
absolute orientation, I need to grab the compass once again
on the little red square
and drag it and drop it on to my absolute axis system
in the lower right corner.
Once I release, you'll notice the compass
now returns to its orientation proper to absolute.
