dragon8

dragon8 is a program that optimizes the distribution of a given number of points within a given shape according to some criteria.

dragon8 is currently in development.

dragon8 is a "zápočtový program" for the Programování 3 class.

best packing of n = 13 points inside a circle found by the program

best distribution of n = 50 points inside a square with lowest energy (~1/r potential) found by the program

best packing of n = 1500 points inside a regular pentagon found by the program

best distribution of n = 1500 points inside an equilateral triangle with lowest energy found by the program

dependencies

• CMake 3.16 or higher
• CImg 2.9.4
  • a header-only image-processing library
  • site: http://cimg.eu/
  • repository: https://github.com/dtschump/CImg
  • v.2.9.4 download: https://github.com/dtschump/CImg/archive/v.2.9.4.zip

how to compile and run

1. add CImg (see above under dependencies)
   1. unzip the downloaded archive
   2. copy the extracted CImg.h file into the /src directory inside (a clone of) this repository
2. create a CMake build directory; for example
   1. create a directory in /build/release
      • <repo_dir>$ mkdir -p build/release
   2. let CMake create the build files from the contents of the /src directory
      • <repo_dir>/build/release$ cmake -DCMAKE_BUILD_TYPE=Release <repo_dir>/src
   3. hereinafter, we refer to this build directory (here <repo_dir>/build/release) as <build_dir>
3. let CMake run the compilation
   • <build_dir>$ cmake --build .
4. run the generated executable
   • <build_dir>$ ./dragon8
