realtime 2d and 3d (like wolfenstein) ray tracing with opengl/sdl around simple shapes
space key to switch between 2d and 3d views
controls are a bit like in a fps game :
arrow key to move
mouse to view around
the 2d view displays the point of view as a light source that casts shadows behind the shapes
you need opengl and SDL1.2 libs with the include files in /usr/include
to build, go in the root folder of the repository, then:
mkdir bin
make
to execute, go in bin dir, then:
./app
