How do I create diamond like fractals on a rounded face?

I've got a real organic rounded shape that when viewed from top/down it looks like of like an egg. I'm trying to create diamond like cuts/fractals across the face. The face is currently round, but I want to make each fractal with a flat face.

 

Bassically I'm trying to convert the nice rounded face into a bunch of flat triangles which will still be angled to form the overall curved surface. Imagine a half circle, but instead of having a nice smooth curve on the top, it's got 5-6 flat faces that still form the "half circle" curve.

 

If anyone could share tips or methods to make this, it'd be appreciated. I've been trying to cut away from the base object but get jagged corners and faces that are all on different levels.

Could you attach the ScreenShot which added the decription on it? This will make us know your idea more quickly.

 

Thanks.

What would also help is to have examples of what you have tried showing what you do not like.

 

Maybe we can open this up to the community and see who can design the best looking cut diamond since that is the style/look you are going for.  I big thumbs up to the best cut with steps provided.  Renderings would be cool.

Mike Aubrey had a video of making a cut diamond shape a while back- it might have been on one of the hangouts. That might be worth trying to dig up.

I used a T-Spline primitive to create the basic shape and then Creased all the edges.  Make sure Select Through is turned on in the Selection Filter on the tools at the top of the screen.  You can then convert to a Solid once the shape is right.  Here is a video where I also used the Soft Modification to shape it.  Looks like fun.

I noticed something when looking at top down views of diamonds.  It was not a surprise to me that the cuts are symmetrical around the face.  What did surprise me was how simple the geometry looked from top down.

This made me think that I could break the geometry down into 3 (or more) levels and project these edges as a starting point for the diamond.

After I made the sketches and projected the end points onto a 3D sketch I started filling in the facets until I had enough to create a circular pattern.

If you can see it, I messed up with the middle tier (not sure if I am getting these terms right so let me know) and it is a little set in and would be hard to manufacture.

 

These are the basics that I could think of.  Of course, Paul's example was a lot faster.  This method will give you some ideas for starting points.

 

Hope that helps.
