OCULA is a unique collection of plug-in tools for NUKE that solve common problems with stereoscopic imagery, boost productivity in post production and ultimately help deliver a more rewarding stereoscopic viewing experience.
Problems addressed include:
The plug-ins are designed to automatically replicate key processes on left and right channels and help artists polish and refine stereoscopic material, literally removing headaches from the final viewing experience. OCULA, created by The Foundry's SCI-TECH Award®-winning R&D team, uses algorithms to work out the geometrical relationship between left and right cameras and generate disparity maps.
Disparity maps track and correlate the differences in positional space and movement between corresponding pixels in the left and right cameras, delivering pixel-level control over images. Knowing where disparities occur, OCULA tools apply corrections by warping, stretching and squeezing only the areas of an image that require treatment. Image manipulation using disparity maps is different to the X, Y or Z-axis shifting of images, where only whole image planes are being shifted.
These building blocks enable OCULA to assist in correcting issues such as vertical alignment and localised colour density differences, and focus mismatches, saving artists a huge amount of pain in performing day to day tasks such as keying and tracking which can become very cumbersome on uncorrected footage.
The OCULA plug-in set contains additional tools that facilitate the copying of rotos and paint strokes from one eye to the other, reduce interaxial separation, performing stereo retimes, create new views from a stereo pair and generate per-view depth maps. All corrections can be made to the left and right eye channels either together or separately, minimising or eliminating discomfort from the stereo viewing experience.

"OCULA is at the very heart of the new post-production tools that have emerged to deal with stereo. NUKE and OCULA were used extensively on Avatar, and we explore the lessons learned with Simon Robinson, Chief Scientist of the Foundry. OCULA, in particular, is a real partnership between filmmakers on the cutting edge and the UK software developer." Read the full fxguide article.
