I first found out about and downloaded TopMod, a free Windows-only modeler (download here
), when I came across some Bryce renders that used some of the models created with TopMod. It's definitely not the most user-friendly software, but it has a LOT of neat options once you get familiar with the interface. One of the cool mesh subdivision methods it uses is called Doo-Sabin, which is what I used in creation of this model. I highly recommend that if you're going to try this software out, you watch the online videos or you may never get anywhere with it.
At any rate, here's a simple render of the model. Not entirely happy with the outcome as you can see the edges aren't as smooth as I wanted (I thought I'd smoothed it out enough, but I guess not.) But, the render time was 2 hours and 20+minutes. Simple chrome texture, HDRI image for reflections, MonteCarlo Global Illumination, & no additional lights.
I'd love to have access to a 3D printer where you could actually have a real copy made of these models. Any way, thought I might as well share even though it's not the best.
