Stereo
Blocks
2D to 3D Conversion

September 2010
This
anaglyph stereoscopic video was created from 2D footage that was
converted to 3D using PFTrack, Maya and Nuke. After the footage
was matchmoved in PFTrack, I used Maya to set up the stereo cameras
and render out new views for the Left & Right eyes. I added
some new CG foreground elements to enhance the feeling of scene
depth with added parallax. Nuke was used to composite the elements,
do colour corrections and create shallow depth of field using a
Z-depth pass rendered out of Maya.
I filmed
the sequence on my Canon 550D/T2i camera using my homemade drawer
slide dolly rig.

BREAKDOWN NOTES:
PFTrack
- correct
for lens distortion and render out new undistorted plate
-
camera tracking/matchmove
Maya
- camera
projection onto matchmove geometry
-
add new CG foreground elements to enhance the scene depth with
additional parrallax
- set
up the stereoscopic cameras' convergence and stereo base separation
(The main control camera for the stereo pair is point &
orient constrained to the matchmoved camera from PFTrack)
- render
new Left & Right eye views
-
render out Z-depth pass
Nuke
-
composite new CG elements onto the original plate
-
colour corrections
- suppress
the vibrant red and green colours on the blocks for better anaglyph
viewing
-
Z-depth grade and blur (DOF) to create monoscopic depth cues,
adding to the overall "3D" feeling of the scene
-
render final anaglyph stereoscopic sequence
Premiere
-
video assembly, titles, breakdown sequence, add music track
