Stereo Viewing

Viewing stereo image pairs in Toxik 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.

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:

Swipe south in a Player view and select the Streams tab.
Select Anaglyph from the Stereo Mode menu.
From the Tools tab, select Stereo Streams from the Streams folder and drag it to the Schematic view.
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.

The stereo image pair is displayed in anaglyph mode in the player. You can view the image with inexpensive tinted glasses.

Toxik 2010 supports special-purpose stereo viewing hardware, such as quad-buffered stereo monitors, or 3D DLP (TM) monitors. These stereo viewing devices are supported through Toxik video preview devices. You must select a video preview device that matches your stereo viewing hardware from the Video Preview device list in the User Preferences window. The default video preview device is None.

Select:	To:
None	keep the default setting. Use None when you do not want a video preview device to be active.
Mono	view a video preview device that is just a window that shows one stream. You can put the window on another monitor if you have one. You can then view the contents of a player in a window on a second monitor. If you only have a single monitor, use Alt + Tab to view it.
DLP-3D Preview	view stereo pairs using DLP -3D monitors that support active shutter glasses—see Active Shutter Glasses.
Segmented Frame Preview	view stereo pairs using circular polarization monitors with passive polarizing glasses—see Polarizing Glasses.
Quad-buffer	view stereo pairs with polarizing glasses using monitors based on linear polarization —see Polarizing Glasses.

NoteQuad-buffer will only appear in the Device list if you have a second graphics card to output the left and right streams.

To view stereo pairs in video preview devices other than the Player:

Select the Video Preview device from the Device list from the User Preferences tab. If your video preview device is None, a Stereo video preview device will show nothing.If you switch to a stereo video preview device and you don't have a stereo pair, the stereo video preview device will show the same image in the left and right eyes.
Change the stereo mode to Segmented Frame Preview
Click in a Player view to make it current. The stereo pair is displayed.
Select a node in the dependency graph and change its parameters. Changes are made in the 3D scene both in the Player and in the video previewing device.
