Using Previzion Data in 3D Equalizer

Previzion data can be used with 3D Equalizer by using two tools to allow the importing of that Previzion take data.

Previzion take data will be recorded as a Collada (.dae) format.  This will then need to be converted into a Syntheyes format (.txt) through TakeConverter.

Read our  “Working with Take Converter” page for more information about using TakeConverter.

You will then need to download a Script (python) from Dashboard and install it in your 3D Equalizer installation folder.  We have two versions of the script:

  • Stereo Data should use the import_previzion_stereo.py.  Click here to download it from Dashboard.
  • Regular (Monoscopic) Data should use import_previzion_mono.py. Click here to download from Dashboard.

These should be installed into 3DE/sys_data/py_scripts folder.

Then, in 3D Equalizer, for Stereo 3D Projects:

  1. Make sure that the dominant camera is selected and is set to a stereo camera.
  2. Select Python->Import Previzion v.03, and pick the output .txt file from Take Converter. The dominant camera should now have position, orientation, focal length, and IO data imported.
  3. In the Attribute Editor lens tab, set the Filmback Width and Height to Fixed, and enter the correct values
  4. Set the Focal Length to Adjust
  5. In the Attributes Editor camera tab, set the lens focal length to dynamic (zooming). It should show the first frame input value.

and for single-camera monoscopic projects:

  1. Select your camera.
  2. Select Python->Import Previzion v.03, and pick the output .txt file from Take Converter. Your camera should now have position, orientation, focal length, and IO data imported.
  3. In the Attribute Editor lens tab, set the Filmback Width and Height to Fixed, and enter the correct values
  4. Set the Focal Length to Adjust
  5. In the Attributes Editor camera tab, set the lens focal length to dynamic (zooming). It should show the first frame input value.
