Details

This program writes a simple tabular file containing the tree's data – one sample per line with space separated coordinates and values. These may be interrupted as points in 3D, and graphed by tools like GNU Plot. On Windows running MSYS2, the following command sequence will produce a graph on the screen:

make hello_world_regular ./hello_world_regular.exe gnuplot.exe ../examples/hello_world_regular.gp
