Overview
Cube making , in Vegas ..Orientation and Rotation apply to Vegas and Movie Studio .Orientation and Rotation are greatly different ,even though they maymight appear to do the exact same thing.
description of Orientation( Object Space ) and Rotation( World Space )
.
.
2 cubes , ( i didn’t put the Top and Bottom faces on the cubes )
.
.
.
when the “Edit in Object Space” icon is Blue , we are in “Object Space”
Object Space uses “Orientation” . The 4 Boxes in the Work Space
on the right side ,
will rotate the cube by adjusting the “Orientation Digit Box” values .
.
wihen the “Edit in Object Space” icon is Gray , we are in “World Space”
World Space uses “Rotation” . The 4 Boxes in the Work Space
on the right side
will rotate the cube by adjusting the “Rotation Digit Box” values .
.
.
it is possible to build a cube( in Vegas ) , so that the Orientation and Rotation digit boxes
appear to do the Exact same thing . If so , then why do we need 2 sets of
rotation dialogue boxes ?
We can select Object Space and use Orientation to “Pose” our cube .
then we can switch to World Space , and use the Rotation to actually
do our intended rotating .
.
Orientation is keyframable too , so we could have dynamic Posing
on the Time Line .
.
Rotation dialoge also has x y z offset boxes so we can position the “point of rotation” .
which is more indictive of Wold Space .
.
Orientation has no x y z offsets , because Orientation manipulates the cube
in the cube’s own centermiddle “Object Space” .
.
consider ,…a 3D modeler program , Blender ( free on Steam ) . make a cube
from 36 vertices( 3 vertiicies to make each triangle ) , 6 Faces , 6 Quads , 12 Triangles
( the cube is made in it’s own Object Space Coordinate System ) .
Now import that cube( .obj .x file ) , onto a World Space’s Origin .
usually , the cube’s vertices are Transformed into world space Coordinates , to
position the cube , as needed , into world space .
Again , Rotation dialogue has xyz offset boxes , and the xyz position boxes
too , are in World Space .
Special note:
if you have 6 seamless images , you can make a “Skybox” , with Vegas .
then “Move” into the middle of the cube , and it will look like you are in a
hemisphere of a Sky with clouds ,…assuming the 6 images were ” blue sky with clouds” .
video games use skyboxes .
.
.
below , is a critcal screen shot , of how the Faces are setup .
each Generated Media is 1920 x 1080 , so external images can be imported
at 1920 x 1080 , or import 6 videos , 1 video per Face .
( ie; texture each Face of the cube with a video , instead of 6 still images )
note :
the xyz dimensions are set to 1080 1080 ( square )
in the Track Motion dialogue .
The Parent Track , Track Motion settings are , 1080 1080 1080 Width Height Depth
and note the Z-axis setting of -540
the remaining 5 Faces are positioned to line-up with this Reference Face .
.
use the Parent Track , Track Motion xyz-position digit boxes ,
of each cube to position each cube individually , into world space .
The Top most parent track , track 1 , can position Both cubes
simaltaniouslly , if needed . ( both cubes are in parallel , feeding track 1 )
( cube 1 and cube 2 are at the Same childindented Level )
.
.
in Object Space , no matter how we xyz position the Event , with Track Motion dialogue ,
uisng “3D Source Alpha” Blend mode ,
if we Orientate it ( Object Space ) , it will always rotate the Event atusing the Event’s
Centerorigin ( that’s “Object Space” )
.
.
one more time :
When the cube is correctly made as shown here,… Orientation( Object Space ) , will ALWAYS
rotate the cube fromon it’s centermiddleorigin ( of the x y z axis ) .
we can use xyz Positioning , to move the cube to a new screen World location , but ,
Orientation( Object Space ) will still rotate the cube about it’s central origin .
( we can use the Work Space boxes on the right side of the Track Motion dialogue )
Next , we can use Rotation( World Space ) with xyz offset , to make the cube
Orbit another cube , or it can Orbit any point we want , including the cube’s origin ,
or we can use xyz offset to cause the cube to rotate on one of it’s edges .
( we can use the Work Space boxes on the right side of the Track Motion dialogue )
be sure to Toggle between
( Orientation ) in Object Space , “Edit in Object Space” icon is Blue
to ( Rotation ) in World Space , “Edit in Object Space” icon is Gray .
.
i can use Orientation( object space ) to make a cube rotate about it’s middleaxis ,
then i can use Rotation( world space ) to make that cube orbit .
Planets spin on their axis as they orbit ,…our Vegas cubes can do that too .
