User Issues in Stereoscopic 3D Displays – a free SID webinar

6.9.2011

SID is offering a free webinar – “User Issues in Stereoscopic 3D Displays”. It will take place on Thursday, June 16, 2011 at 12:00 PM (noon) Pacific Daylight Time. The presented is Dr. Martin Banks, a vision scientist at Visual Space Perception Laboratory at UC Berkeley.

Dr. Banks will discuss the use of stereoscopic 3D displays in industry and impact on the user. In addition, he will discuss technical criteria relevant to effect use of stereoscopic 3D displays.

In this Webinar you will learn:

  • A variety of user issues.
  • The temporal protocols used in stereo 3D and how they affect perceived flicker, motion artifacts, and depth distortions
  • Head roll, vertical eye movements, and visual discomfort
  • Visual-vestibular conflict and nausea
  • Vergence-accommodation conflict
  • Vergence: the inward or outward turning movement of the eyes in convergence or divergence;
  • Accommodation: the focusing of the eyes to make the image on the retinas sharp.
  • Vergence and accommodation in natural viewing; coupling
  • Vergence and accommodation in stereo displays
  • Optometric measures of discomfort
  • Evidence that vergence-accommodation conflict with stereo displays causes discomfort: blurry vision, tired eyes, and headache
  • The effect of viewing distance
  • The effect of the direction of the conflict (content in front of the screen or behind?)
  • Maintaining comfort in different viewing situations
  • Relating these findings to current practice

You’ll be able to view the webinar here (on June 16). http://connect.livewebcast.net/sid/

Exploring the Principles Behind 3D TV (free online interactive course)

6.9.2011

The IABM Training Academy has posted an introductory online course on 3D. The course takes about an hour to complete and provides an introduction to 3D and how it works for TV and in the cinema. No prior knowledge is required to take the course.

You can find the course at this link: http://www.iabmacademy.org/Online_Courses/3D_Free/player.html

WARNING: the site asks you to go through a simple set-up verification sequence before you enter the actual course.

Specification for Naming VFX Image Sequences Released

ETC’s VFX Working Group has published a specification for best practices naming image sequences such as plates and comps. File naming is an essential tool for organizing the multitude of frames that are inputs and outputs from the VFX process. Prior to the publication of this specification, each organization had its own naming scheme, requiring custom processes for each partner, which often resulted in confusion and miscommunication.

The new ETC@USC specification focuses primarily on sequences of individual images. The initial use case was VFX plates, typically delivered as OpenEXR or DPX files. However, the team soon realized that the same naming conventions can apply to virtually any image sequence. Consequently, the specification was written to handle a wide array of assets and use cases.

To ensure all requirements are represented, the working group included over 2 dozen participants representing studios, VFX houses, tool creators, creatives and others.  The ETC@USC also worked closely with MovieLabs to ensure that the specification could be integrated as part of their 2030 Vision.

A key design criteria for this specification is compatibility with existing practices.  Chair of the VFX working group, Horst Sarubin of Universal Pictures, said: “Our studio is committed to being at the forefront of designing best industry practices to modernize and simplify workflows, and we believe this white paper succeeded in building a new foundation for tools to transfer files in the most efficient manner.”

This specification is compatible with other initiatives such as the Visual Effects Society (VES) Transfer Specifications. “We wanted to make it as seamless as possible for everyone to adopt this specification,” said working group co-chair and ETC@USC’s Erik Weaver. “To ensure all perspectives were represented we created a team of industry experts familiar with the handling of these materials and collaborated with a number of industry groups.”

“Collaboration between MovieLabs and important industry groups like the ETC is critical to implementing the 2030 Vision,” said Craig Seidel, SVP of MovieLabs. “This specification is a key step in defining the foundations for better software-defined workflows. We look forward to continued partnership with the ETC on implementing other critical elements of the 2030 Vision.”

The specification is available online for anyone to use.
