From left to right: adenine, cytosine, thymine, guanine. They took about ten minutes each, thymine a little longer than the others because of the ‘antler.’ I found that I could copy-and-paste a lot of the molecular structure from previous work, for example the pentagonal ring of guanine is the same as adenine.
Anyway, here are close-ups:
In case it’s not obvious, white is hydrogen, carbon is black, nitrogen is blue, and oxygen is red. And they’re rather pretty renderings, if I do say so myself.
I should also do uracil, it’s like the fifth Beatle. I notice that at this time the wikipedia entry for uracil has no 3D model. Hee hee, I’ll beat wikipedia to it!
And when will I upload this to Google 3D Warehouse? I think I should give it a day. For some reason, I can stare at a project for hours and can’t see any more errors. Then I glance at it the next day and a glaring error is staring me in the face. I also notice that blog errors often escape notice until I publish, no matter how carefully I preview. That has something to do with quantum physics, according to Einstein or Dogbert.
So it’s probably a good idea to wait.
