NOTE To view the individual streams, use the Player 0, (next stream) and
Shift + 0 (previous stream) to cycle to the next and previous streams produced
by the Player target. You can also view a stream by swiping through the
Player south gate, opening the Streams tab and selecting the stream you
want to view from the Stream value editor.
Stereo Viewing
Viewing stereo image pairs in Composite is supported through an anaglyph
display mode in the player, and by quad-buffered, 3D DLP, and left/right
segmented frame plug-in video preview devices.
If you do not have stereo footage available, you can use the Reaction tool to
create new footage by rendering a scene using a stereo camera rig—see
Setting
up a Stereo Camera Rig
on page 293.
An anaglyph is a stereoscopic motion or still picture in which the right
component of a composite image usually red in color is superposed on the
left component in a contrasting color to produce a three-dimensional effect
when viewed through correspondingly colored filters in the form of glasses.
Anaglyph mode is applied after the display modifier. For example, if the display
modifier performs gamma encoding, or tone mapping, the result is encoded
for stereo display using an anaglyph after the gamma encoding or tone
mapping.
To view a stereo image pair in stereo anaglyph mode in a player view:
1 Swipe south in a Player view and select the Streams tab.
2 Select Anaglyph from the Stereo Mode menu.
3 From the Tools tab, select Stereo Streams from the Streams folder and
drag it to the Schematic view.
4 Connect the stereo image pair left image to the left input of the Stereo
Streams node and the right image to the right input of the Stereo Streams
node.
