If you plan to work on a 3D project in Pixera using a UV-Map, you will be able to perform also a 3D calibration with Pixera Autocal Plus following this step by step guide.

1. Choosing the correct calibration executable

Please choose the the correct calibration executable. Learn how to identify and launch the appropriate Pixera Autocal executable here: /documentation/integrate-media/av-stumpfl-pixera/autocal-standalone/

2. Scan projectors

Perform a camera calibration of the projectors following the classic way of camera based calibration: /documentation/core-video-tutorial/

3. Import and align the 3D UV-Map

Important points for 3D calibration:

• Please use the full resolution of your camera for the calibration, later you will need to add the FoV of the camera used. The Field of View for the camera can be usually found in datasheet and it is given for the full resolution usage, so if you have used cropped camera image for the calibration you will need to recalculate the camera FOV by yourself.
• Do not apply any warping and keep your VC untouched full screen.

Import and align your 3D model:

• When you perform the calibration using a camera, the calibration result will be mapped using the calibration camera perspective, so camera – is the default content space for the calibrated projection.
• However, by the most of applications the content must be displayed and evenly distributed onto a projection surface or onto your custom content space. The custom content space for the calibration in this case is the surface of the 3D model which is used for projection which has to have a UV texture coordinates distributed properly on the projection surface.
• You can import your 3D model in the following formats:
  • *.obj
  • *.dae (COLLADA)

Align now your UV-Map on the screen following this quide: /documentation/vrsim-3d-calibration/mrd-adjustment/

4. Perform conversions:

Follow this guide to perform the final conversions on your calibration: /documentation/vrsim-3d-calibration/#Step_4_Final_conversion

5. Export your files in .vwf to load them in Pixera:

Save and export in .vwf like in this guide: /documentation/core-export-calibration/

Refer to this chapter to learn how to load the *.vwf file in Pixera: /documentation/integrate-media/av-stumpfl-pixera/autocal-standalone/
