all sam will do is make the bottom plane less contrasty and more white.
to make things brighter try (in main()) raising the lightsource.
you do that by changing MV(0.0,900.0,0.0,ls) to something like
MV(0.0,3000,0.0,ls). I think you'd also want to enlarge the radius if
you did this.

changing the light source should help.

once again a problem in main().
under case ('S'), there is an
if statement reading as follows:
if(argv[i][2] < '0' || argv[i][2] > 9)
and it should be
if(argv[i][2] < '0' || argv[i][2] > '9')

the option should then be given as -S0.9
