How can I make the edges of the drawers without smoothing?

Question

I am creating a dice game for iPhone. I use SIO2 as an engine, but I think this question is more general for OpenGL.

Since the iPhone does not have support for smoothing, my bones look a bit sharp. If possible, I would like to make the edges of the cutter rounded and smooth, rather than sharp. I found one application, MotionX, that succeeds, and I think that without using anti-aliasing. See the screenshot here . If you look closely at the edges of the bone, you will see a floating transition from the brightly lit top face to the shaded side surface. It looks kind of far from here.

Does anyone know how to recreate such an effect?

Answer 1

If you look closely at the edges of the cubes, you will see a floating transition from the brightly lit top face to the shaded side.

Not sure if the iPhone supports this, but you can achieve this effect with a normal card:

Of course, you need to truncate the corners to get them round enough for the normal map to leave you to the end.

Answer 2

You need to create bones with slightly rounded edges and corners. Thus, there will not be a sharp transition between each person.
