3DEqualizer4 R2b1

  • 3DEqualizer4 R2b1 3DEqualizer4 Release 2

Dear Friends of 3DE!

After an initial development time of roughly 6 months we uploaded the first beta version of 3DE4 Release 2 yesterday to the download area of our website. As usual, in order to run this new software upgrade keys (compatible to R2) are needed!

Here is an overview about r2b1's new features:


We spend an awful lot of time integrating sophisticated camera synchronization into 3DE's calculation core which properly interacts with all previously available features (such as stereoscopic, constraints, survey, etc.).
Synchronization allows you to make use of so-called witness cameras (tracking object point groups, simultaneously shot from different angels using multiple cameras).
In addition, this feature allows you to extract precise motion capturing data (mocap point groups, static as well as moving cameras).

massive python update

3DE4 R2 contains a huge amount of new python commands. These new commands allow to access more attributes of 3DE4's project database, and provide a lot of possibilities to develop much more complex and interactive custom user interfaces.
A good example of what is possible now, is demonstrated by the new "Push Points v2.0" script which opens a non-blocking custom window featuring several buttons and an interactively changing user interface.
In addition to menus, python scripts can now be executed through buttons which are placed into 3DE4's display area.
Finally, there is a great number of cool new python scripts such as rolling shutter compensation, merge projects, convert to stereo, store/recall camera, etc.

new lens parameter "custom focus distance"

Lens objects now contain an additional parameter called "custom focus distance". Right now, this parameter is used by 3rd party lens distortion plugins only, which allows to handle focus (pulls) more precisely.
We will extend 3DE4's own distortion models to make use of this new parameter, soon.

integrated undistort option

Lineup-, Overview- and Distortion Edit Controls now provide an option for undistorting the imported footage in realtime, which speeds up the workflow, especially for Lineup, a lot.

streamlined GUI

3DE4's Attribute Editor, Parameter Adjustment, Python Console and Image Controls window can now be embedded into a Main Window's pane structure (and saved into environments), which makes it much more easier to work with 3DE4 on single monitor systems.
Points can now be locked to prevent any unintended editing, or hidden from 3DE4's display area entirely.
We added a preset function to 3DE4's Image Controls window which allows you to store/quickly jump between 10 different configurations.

In addition, we added a lot of minor features, fixed some bugs and improved 3DE4's performance in general! Please see detailed changelog below...
