Dabarti Capture is tool that helps with capturing high quality textures and surface Normal maps using photometric stereo technique.
Update 0.8.9 fixes:
- Alternative manual activation added.
- Support for manual activation in case there is no internet connection.
- Crash when there is no internet connection.
Update 0.8.6 includes:
- --lightsfile command line parameter for specifying the location of lights.txt
- Improved shadow detection with Shadows threshold that can be controlled with --shadowthreshold command line property. By default set to 0.3.
- Shadows previews are saved to Shadows sub-directory.
- Ability to overwrite output names with --basename command line argument.
- Less artifacts in Albedo Map generation.
- Fixed Depth generation issue when object_mask.jpg is present.
- Fixed wrong image rotation when exif 'Orientation' tag is present.
Update 0.8.0 includes::
- 16 bit tiff input and output support for Pro Users.
- Support of RAW camera files.
- Improved depth map and albedo calculation.
- Less aggressive shadow detection maximizing Normal quality.
- Depth from Normal that works also with tileable normal maps. (PRO)
- Flattening Normal map making tiling easier. (PRO)
- Speed Improvements.
Update 0.6.2 includes:
- New normal calculation method that works better with shadows.
- Improved multi-threading.
- Strip processing for lower memory usage.
- Ability to use object_mask for improved depth generation.
- Reusable light calibration from lights/lights.txt file.
- New command line options. Check out readme.txt and changelog.txt for more information.
- Bonus leaves textures for Pro customers.

Tips for capturing photos:
1. Make sure that camera doesn't move. Use remote or Intervalometer to take photo every 3-4 seconds while you change light direction. Otherwise you will need to align the photos manually and nobody likes that, so use remote.
2. Make sure that highlight from your light source is visible on the spherical probe. For that probe you can use any reflective spherical object. I had success, with light bulbs, pool ball, christmas ball.
3. For reflective, shiny objects you need to use cross polarization. In order to do that you need linear polarization filter for light source and for the camera. There are ready to buy filters for different lenses. For the light source you can order piece of linear polarization filter and fix it in front of the light source. When taking your photographs, you have to basically rotate the light source to remove the highlights.
Currently this tool is command line tool only. Read README.txt for more information or just watch this video to learn how to use it https://vimeo.com/217827234
Installation and licencing:
Start the installation and follow the instructions.
After installation you will need to activate your tool by entering the licence key that you've received after purchasing. You can do that by processing any data set with capture.exe and it will ask you to enter the key.
Activation requires internet connection and after it's successful, there will be activation.lic file generated. Activation works only on that PC, you can back it up and reuse it in future. The licence is valid for single node/workstation only, but there is a limit of up to 3 activations per licence key in case of hardware change. There is no deactivation possible at this stage.
