- [Instructor] We've seen how to
manipulate objects within the 3D world.
Now let's talk about changing our viewpoint
in that 3D world, looking at it from different angles.
In the lower right,
we've got some icons here for our viewport navigation.
And we'll take a couple of movies to cover all of these.
Let's start with just maximizing the viewport.
Sometimes we want a full screen view,
and to accomplish that we'll give focus
to a particular viewport such as this Perspective view,
we can click in it,
make sure it's got a yellow border around it.
And then, in the extreme lower right corner
of the Max interface,
we've got a button Maximize viewport toggle.
Click that once and the active viewport
is going to be full screen,
and click it again to send it back
to whatever the previous layout was.
All right, so that's how to maximize the view.
Now let's talk about moving within the 3D world.
And one way to do that is with the hand tool down here,
and it's labeled Pan view
but that's actually really a misnomer.
Pan, in filmmaking terminology, is short for panorama.
That's when a camera stands in one place,
maybe on a tripod, and rotates left or right
in order to take in different parts of the scene.
This is actually not doing that.
This so-called pan tool is actually more like
a filmmaking truck or pedestal
in which we position the camera somewhere.
So let's try it, so I'll activate this Pan view,
and then click and drag into Perspective view.
Click and drag and move left to right,
and that's a truck.
Click and drag up and down, and that's a pedestal,
or indeed we can move in both at once.
But we're moving in two dimensions here.
We're not actually in a 3D view,
we're in an orthographic front viewport.
We can also constrain that movement
by holding down the Shift key.
So if we just want to move left to right,
we can hold down Shift and drag left to right,
and we're not able to move up and down.
If we only want to move up and down,
hold down Shift and drag up and down.
Same thing in the perspective here.
Hold down Shift and drag up and down and that's a pedestal.
Hold down Shift and drag left to right,
and that's a track or truck.
All right, so that's the so-called pan tool.
Now another thing it's a little bit non-standard
in terms of the terminology here
is the so-called zoom tool,
and that's sort of not really accurate.
The zoom tool is indicated by a magnifying glass icon.
When we activate that,
then if we click and drag in one of these orthographic views
such as the front view, that really is a zoom.
It's an optical effect where we're actually
magnifying the current view.
But if we click in drag using that magnifier glass
in the perspective view,
we're dollying forward and back.
The camera is actually moving forward and back,
and we can see that pretty clearly here.
So in a perspective view,
that magnifying glass is a dolly,
but in these orthographic views,
it's more of a traditional zoom, or an optical effect.
Now, if you do want to zoom here in a perspective view,
that's easily accomplished,
you just use a different tool,
and it's down here called the Field of view.
So click on that, click and drag
and we can get a wide angle shot.
It's now got an extreme wide angle,
or we can zoom in very tight to a telephoto lens effect.
All right, so that's using the Field of view.
Finally, there are a couple of tools here
for framing or zooming into particular objects.
And here in the navigation tools
we've got Zoom extents selected,
and also Zoom extents all selected.
And the word all here does not mean all objects,
it means all viewports.
So let's see what we can do.
Let's select some object.
I've got the select object tool,
we can activate that,
and click on something such as this light fixture.
And then, we can go down here
and click on the Zoom extents selected,
and that's going zoom the current viewport to the selection.
And then, if we click on Zoom extents all selected,
it's going to Zoom all the viewports on that selection.
If nothing is selected, then the current view, or all views,
will zoom to enclose all the geometry.
So I can just click nothing here,
so nothing selected,
and then click on Zoom extents selected,
and that current viewport zooms out to enclose
all the geometry in the scene.
If I clicked on Zoom extents all selected
with nothing selected,
then all the viewports are going to zoom out to enclose
all of the geometry.
All right, so we can zoom back in,
or dolly back in, on our perspective view
using the magnifier glass and get back to where we were.
Those are some of the tools
in the Navigation toolbox in the lower right corner.
