Can someone please tell me how to simplifying this without reverting to me creating a scenegraph?

What do you guys think?

keys 0-9 to move joints

void Render::drawObjs()

    glEnable(GL_LIGHT0);
    glLightf(GL_LIGHT0, GL_AMBIENT, 0.6f);

No matter what, you've got a scene graph. It's either implicit, or explicit. Yours in the above code is implicit.

You could do it in two other ways that look cleaner than one mega-method.

#1 make the individual methods themselves responsible for drawing children. This is sort of an implicit scene graph represented on the call stack

drawHead()
  push/translate
    drawNeck()
  pop

drawNeck()
   push/translate
     drawTorso()
   pop

drawTorso
   push/translate
   drawJoint()
etc

#2 Use a mini scene graph. Just make a small tree object which encodes the translation, and callback function. Trivial amount of code to traverse the tree, calling push/translate/draw/pop/etc.

Thanks.
The second mode looks a lot better.
