From Version 3.6 it is implemented the possibility of decimate the number of points coming for a laser scanner.
The decimation parameters are set in the whitestar.ini file and they are applied to :

  • Input Points from the scanner
    • Use the entry Laser data decimation ratio (1.0000-0.0001)=1.00000000 where 1 means 100% of points taken.
  • Point Cloud Visualization
    • Use the entry Point cloud coarse grid step ( > 0.001)=0.20000000 to define the step of the visualization grid
  • Surface analysis
    • Use the entry Point cloud fine grid step ( > 0.001)=0.02500000 to define the step of the measuring grid
