ProjectionTools 4.2.0 released

The new minor release ProjectionTools 4.2.0 is available.

Below you can find an overview of the most important innovations.

ProjectionMapping support

Now it is possible to calibrate arbitrary screen shapes like mockups and buildings, which include creases and discontinuities.
By providing a 3D model of the surface, ProjectionTools can calculate projector positions, lens-distortion and blending after capturing the usual testpatterns. This results in a correct projection on any complex surface.

The new application MapperPM generates and exports a new type of data.
Furthermore we introduce scanning of unknown 3D surfaces as an experimental feature.

Coded LEDs

Creator and Align now support coded LEDs which allow to find and identify reference points in the complete camera image. Due to the controllable LEDs, which can be embedded into the screen or other projection surfaces, it is not neccessary anymore to define regions of interest previously.

Initial camera positions can now be calculated faster. The result is successful even if camera or screen are moved significantly between subsequent calibration runs.

ProjectionTools 4.1.0

The following innovations have already been made available in ProjectionTools 4.1.0.

The upgrade involved ProjectionTools itself, PatternGeneratorColorMatchnWarp and the domeprojection.com® SDK.

Automatic detection of cutted dots

In Creator and Align you can choose a new calibration pattern of rings, which allows to automatically detect cutted dots. In this way, the dot-pattern less often needs to be adjusted manually. The detected full dots are stored as a dot pattern for following calibration runs.

Coloured blending and black-level correction

Mapper3d supports colour tweaking of blending and black-level correction. This improves software blending and the results of black-level correction in difficult situations.

Tight integration with several 3D engines

The domeprojection.com® SDK, which supports static and dynamic warping, is adopted by more and more 3D engines. It got updated to support the new coloured blending and black-level correction feature (see above). In addition, Mapper3d received a dedicated domeprojection.com® SDK exporter making the export step much more convenient.

Additional new features and improvements

  • Exporting of reference points
  • Creator & Align: Only the image all points is projected on screen when simulating a project.
  • Points that are not part of the dot pattern aren’t detected anymore during image processing (allows later removing of points by editing the dot pattern and avoids false detections).
  • MPCDI exporter: possibility to adjust the level – for better compatibility with systems not supporting the highest level 4
  • Dedicated VI-grade VI-GraphSim exporter added
  • Preview 3D exporter: quicker previews by selecting reduced blending resolution; choosing custom environment texture

Fixes

  • Transfer to align copies camera settings as well.
  • Marker no more disappear when dragging while camera live mode is activated.
  • Creating projects with uncalibrated cameras works again.
  • Fixed randomly broken frames using AVT GigE cameras.
  • Align command line version reports errors as return-value and in console instead of message boxes.
  • Barco Pulse exporter regards individual upload checkmarks.
  • Fixed slight preview error in Brightness-Adjust Widget.
  • Fixed pipeline and modifier stack steps potentially getting shuffled when moving them up/down.

ProjectionTools 4.0

The following features and workflow improvements have already been available in ProjectionTools 4.0.

Speed improvements

  • Much faster handling of screen scans and reference mesh mappings
  • Fast align for projectors that have not significantly moved since last calibration

Workflow enhancements
