3DEqualizer4 R3b2 - Next Milestone in Solving Anamorphic Distortion Issues3DEqualizer4 Release 3
Latest Update: 05/07/13
Dear Friends of 3DE!
The 2nd beta version of 3DE4 Release 3 has been completed. During the last months we were focused on lens distortion - once again!
Here is a brief summary of R3b2's new major features:
A new, generic distortion calculation requester which is much more robust, able to handle every possible lens distortion model and allows to make use of multiple gridshots for calculating a lens object's distortion parameters.
Two new standard distortion models - one for radial the other for anamorphic distortion. Especially our new "Standard Anamorphic Degree 4" model seems to be a real breakthrough. Parameters "Squeeze X & Y" allow to address pixel aspect changes caused by lens breathing artifacts very easily, whereas parameter "Lens Rotation" solves a longtime mystery of anamorphic distortion: badly mounted lenses (thanks to Wolfgang for the useful discussion!).
Vastly improved distortion matrix snapping routines in terms of speed and quality (especially at the edges of the FOV). In addition, there is a new script for smart snapping the initial triple of matrix points.
A new, interactive script for animating dynamic lens distortion parameters by hand, in case no (series of) gridshots are available.
A new script for exporting lens distortion information to Nuke v7 which is based on "gridwarp" - Nuke's out-of-the-box warping node. This removes the immediate need for installing any 3rd party Nuke distortion plugins.
Two new tutorials. The first one covers 3DE's basic lens distortion handling. The 2nd one concentrates on how to address anamorphic lens breathing problems.
An overscan rendering feature integrated into overview controls.
A new, alternative calculation requester for identifying badly tracked (autotracking) points.
3DE's main window timeslider can now be zoomed in and out by the help of the mousewheel.
All editors and browsers can now be combined in so-called auxiliary windows.
