Platform

Program written and tested on Linux 64-bit.
Requires a c++14 compatible compiler

Makefile

Written for GCC on *nix platforms. Requires libglut, libGL, and libGLU to be in $PATH

Changing compile and linking flags

The Makefile can set the environment variables automatically but only if they are not previously exported. If the Makefile seems to be broken, one or all of the environment variables probably need to be re-exported.

$ export CXXFLAGS=-std=c++14 -I.
$ export LDFLAGS=-lglut -lGL -lGLU
$ export CXX=g++
$ make all

Running

Run ./main if it exists otherwise it must be compiled. See above if there are compiler errors.

$ make all
$ ./main
