The reason I only mentioned fltk is I also tried gnuplot (on my linux
pc) and saw that it is too slow for a reasonable number of triangles
(but works).
Btw there is a little bug the last line of calc_cdata
instead of

  + spec*specular(normals(:,1), normals(:,2), normals(:,3), lvec, vvec);

it should be

  + spec*specular(normals(:,1), normals(:,2), normals(:,3), lvec, vvec,
shine);

otherwise the specular exponent has no effect.
