  Why do you do it in such needlessly complicated way?
  The example in the page could perfectly be implemented like this (with
the proper modifications to the library):

#include "povtor.hh" // This is not a C header. Don't name it as if it was.

int main()
{
    Frame frame("c:\\my\\sedlo.pov");

    Camera cam(1050, 950, -500, -300, 0, 1500);
    Light light(2000, 2000, 2000, 50, 5, 5);

    frame << "#include \"colors.inc\"\n#include \"textures.inc\"\n\n"
          << "global_settings {ambient_light rgb<4,4,4>}\n\n"
          << cam << light;

    Cylinder cyl(3); // Could have this kind of constructor to set the radius
                     // If it's odd, you could just do cyl.Radius(3) instead

    for(int x = 0, y = 0; x < 1000; x += 10, y += 10)
    {
	cyl.SetEnds(x,y,0, x,1000-y,1000);
        cyl.Texture.Color(1+sin((x+y)/500), 1+sin(x/300), 1+sin(y/300));
	frame << cyl;
    }

    for(int y = 0, z = 0; y < 1000; y += 10, z += 10)
    {
	cyl.SetEnds(0,y,z, 1000,1000-y,z);
        cyl.Texture.Color(1+sin(y/300), 1+sin(z/300), 1+sin(y+z/400));
	frame << cyl;
    }

    frame.Render();

    return 0;
}
