Read it if you don't understand what the map & light source data structures are all about.

Annoyances: although libfov is a c library, for some reason compiling a file that contains #include <fov/fov.h> need to be compiled as a c++ program and not as a c program. For instance: A file containing the following:

#include <fov/fov.h>

int
main(){
    return 0;
}

will compile as libfov-test.cpp but if named libfov-test.c (and therefor compiled as a c file), gcc will produce the following error:

In file included from libfov-test.c:1:

make: *** [libfov-test.o] Error 1

I don't know why, but would be glad if someone could find out the reason and propose a solution.
