hailstones Codes for modeling hailstone structural and electromagnetic scattering properties from stereolithographic measurements. Building Requirements: A C++14 compiler CMake Boost VTK 6 Run CMake and generate the build scripts. Build the project. Usually, this involves typing "make" Run the programs. The Programs Prog1 - Read STL surface meshes and generate volumetric meshes Prog2 - Take volumetric meshes and scale them to match the measured hailstone masses / densities. Prog3a - Convert the volumetric meshes into DDSCAT shape files Prog3b - Convert the volumetric meshes into DDSCAT runs at desired spectral frequency and temperature.
