This is a Raytracing made from scratch in C++, using a C++ wrapper of Allegro I did.
Compile using :
-std=c++11 -lpthread;allegro;allegro_image;allegro_primitives;allegro_memfile;allegro_ttf;allegro_font;allegro_dialog -Wl,--format=binary -Wl,allegro/arial.ttf -Wl,--format=defaultThe last line is required to include the arial.ttf file inside the executable, at link time. This avoids having to share your program and the font file as two separate files.
The optimisation level -O3 is highly recommended as it's 5 times as performant as lesser ones.
