The
example below show how the Camera Window is changed to create
perspective views witch enable the creation of of
compelling 3D movie effects. Using the StillMotion
Creator is the best way to gain experience and insight into
creating these effects.
Perpendicular
View This is the view with the camera parallel to the
plane of the image. Note rectangular Camera Window
Down Perspective
The Camera Window is tilted up to the plane of the
image as is represented by the trapezoid shape creating a
view of moving down toward the bridge.
Up Perspective
The Camera Window is tilted down to the plane of
the image as represented by the trapezoid shape of the
Camera Window. The effect is looking up at the
bridge.
The #2 move in the video in
Video Stream Fly-by is
created using this type of perspective manipulation
Exaggerated Down
Perspective A border is added to the image giving the
effect of it being mounted on a flexible sheet. This
effect is as with the next four are used to create The
3D Movie Demo. The
technology used in creating these perspectives is called an
affine transform and commonly, as you will see in the
3D Movie, rubber sheeting
Rotated
Perspective Here the perspective (Camera Window)
is rotated 90 degrees and the center shifted to the left.
The effect is dramatic
Rotated
Perspective The rotated perspective is moved to the
right with the results shown. The image sheet
is rotated away from the viewer.
Using this and the
previous frame as key frames (end points) for a move (motion
sequence0 shows the image flying and bending in a curved path
away from the viewer.
Rubber Sheet
The shape of the Camera Window can be changed by
selecting shift key and grabbing the corners. Here an
exaggerated shape simulates a wide angle view with the camera
set at the edge of the sheet.
