    LAStools are a set of simple command line tools (including source code) for converting, viewing, comparing, and compressing LIDAR data:
  • txt2las.exe (R) for converting from standard ASCII to binary LAS
  • a corresponding las2txt.exe (R) for the reverse
  • lasview.exe (R) for viewing LAS files and lasinfo.exe (R) for listing their contents
  • las2las.exe (R) for extracting points and modifying LAS files
  • C++ classes LASreader and LASwriter for reading writing of LAS
    •      		example data:
  • LP360_Sample_Data.rar
  • OptechSampleLAS.zip
  • LeicaSampleLAS1.zip
  • LeicaSampleLAS2.zip

    Streaming Delaunay is I/O-efficient software (including source code) for computing Delaunay triangulations of large uniform distributed point sets in 2D and 3D.
  • first you need to use spfinalize.exe to finalize your points spatially
  • then spdelaunay2d.exe for 2D (see README_2D.TXT)
  • or spdelaunay3d.exe for 3D (see README_3D.TXT)
  • visualize point clouds and the Delaunay triangulation process with sp_viewer.exe
  • look at resulting tri meshes sm_viewer.exe or tet meshes sv_viewer.exe
