After Effects anaglyphic 3D plugin
Developed with Adobe Pixel Bender. Similar to Apple Core Image of Shading
Languages, it does image processing completely in the graphics processor without
overhead for the CPU. The result is a great quality, realtime anaglyphic
image processing filter with multiple adjustment posibilities.
Features:
• Four anaglyph types (gray scale, color, half-color, optimized)
• Left, right and difference image
• swap left-right image
• horizontal and vertical offset for left image
• gamma adjustment
Plug
in After Effects interface
Download it here
Installation:
Copy the anaglyph.pbk to ...\Adobe After Effects CS4\Plug-ins\Effects
Restart AFX and you are ready to go.
Usage:
Create two layers, one with the left and one with the right eye footage.
Apply the "Anaglyphic 3D" effect in the "stereo 3d" category to the left
eye footage
and choose right eye layer as the "input 2", you can make the
right layer invisible. Choose the an anaglyph type and adjust the settings.
Inspiration was David Shelton's "Optimized
Anaglyph Filter". Anaglyphic algorithms from 3dtv.at
Stereoscopic
Conversion/Display patch for Quartz Composer
A patch for
Quartz Composer to display and convert from/to various stereoscopic formats.
Most conversions are realised as Core Image filters and executed in the GPU.
The patch does work for still images and QuickTime movies.
The stereo pairs
should be already aligned, a future version will allow for manual alignment
in translation, scale and rotation.
Stereoscopic Conversion/Display patch for Quartz Composer
Input formats:
• separate left/right
• side by side
• top/bottom
• row interlaced
Output formats:
• anaglyphic (true, bw, color, half-color)
• side by side
• top/bottom
• checkerboard interlaced (DLP)
• row interlaced (parallax barrier and auto stereoscopic)
• left/right |
Other parameters:
• swap left/right
• horizontal parallax offset
• gamma adjustment
Outputs:
• stereo image
• left image, right image
• display width and height (to correct for aspect ratio) |
Stereoscopic/3D camera rig alignment tool
This patch, based on Quartz Composer, allows live video input from two cameras
to physically align and calibrate the camera pair. It turned out really useful
to calibrate the stereo rig I designed.
Do to limitations in QuartzComposer (it allows only to grab one live image from
one camera at a time), it was necessary to use 3rd party software to grab and
display the live video streams and a QC plugin to grab the portion of the screen where
the videos are displayed to use them within QuartzComposer.
Output formats:
• anaglyphic
• row interlaced (autostereoscopic displays)
• screen blend
• Silhouette Luma
• Difference blend
Other parameters:
• parallax adjustment
• rotate one of the camera images 180º
• left and right camera image offest
Ingridients:
• two DayStar XLR USB video grabbers
• USB Vision grabber application
• Apple
Quartz Composer
• V002 Screen Capture plugin for QuartzComposer
