3D Compositing
3D compositing is like track motion on  steroids. With 3D compositing, you can move video tracks anywhere 
in space.
With 2D compositing (and in previous versions of Vegas Pro),  you can move video or images along the X or 
Y axes, and you can rotate  video along the Z axis. With 3D compositing, you can move or rotate along  the 
X, Y, or Z axes to create distance, depth, and perspective.
There are two basic rules to 3D compositing:
1.  When you have a 2D track in the track list, 3D tracks  below that track are rendered in 3D and then 
composited as a 2D image.  
2.  A 2D track at the root level (flush to the left of the  track list) acts as a barrier to interaction between 
3D tracks.
In the following examples, both text tracks have been rotated in 3D:   the "hot" track is rotated 
toward the user, and the "cool"  track is rotated away from the user.
In the first example, the two tracks intersect along their rotation   axis. In the second example, 
adding a 2D track above the "cool"  track causes it to be rotated in 3D and composited as a 2D 
image so the  "hot" text is displayed above it without intersecting:
