CGALTesting

An exploration of the CGAL tools and functions

Setup steps

• Install CMake (via Installer)
• Install Visual Studio (via Installer)
• Install vcpkg (via command line)
  • Either download the zip, or clone from github
• Install CGAL (via command line)
  • Done totally via command line in the location of vcpkg’s root folder
• Install qt5 for CGAL (via command line)
  • This is for visualising with the meshes
  • For lighter weight install, can just install the qt5[CGAL] module and not the entire qt5

Project setup steps (From scratch)

• CMake only

  • Create folder of project
  • Create CMakeLists.txt file in root project folder
  • Create .cpp file for codes
  • Write codes in CMakeLists.txt to create a project and link CGAL and the required qt5 components to the project and executable
  • Make a ‘Build’ directory for building
  • Run ‘cmake-gui’ to configure the linking
    • Includes linking the location of the vcpkg.cmake file (x86 or x64 installed version of CGAL)
  • Run ‘cmake –build .’ to build the project and executable
  • Copy .ply file into the built executable’s root directory
    • This should be located deeper inside the ‘Build’ folder
  • Run the executable

• Visual Studio

  • Create project option in Visual Studio
  • Select to create a CMake project
  • Create .cpp file for codes
  • Write codes in CMakeLists.txt to create a project and link CGAL and the required qt5 components to the project and executable
  • Edit the ‘CMakePresets.json’ file to include “"CMAKE_TOOLCHAIN_FILE": "\vcpkg\scripts\buildsystems\vcpkg.cmake"” under “cacheVariables”
    • Saving changes to the CMakeLists.txt causes Visual Studio to wipe the build directory and rebuild the executable and do the appropriate linking immediately
  • Copy .ply file into the built executable’s root directory
    • This should be located deeper inside the ‘Build’ folder
  • Run the executable via pressing the run ‘Current Document’ button on the top bar in the correct x64 or x86 configuration

Processes controls

Each of the processes have a boolean that controls if the process is executed or not

Processes:

• Downsampling
  • skipDownSampling
• Outlier removal
  • skipOutlierRemoval
• Surface Reconstruction
  • skipSurfaceReconstruction

Drawing the mesh has two current methods, draw a SurfaceMesh type, or a Point_set. Adjust the outputs of the processes to these two types in the 'Draw the mesh' section accordingly
