Chemical Structure Conversion Script
Malte Reimold (intermalte) has developed a script that I have been hoping for for some time… the chemical structure conversion script pdb2blend!
Pdb2blend converts 3d structural molecular data in pdb file format to typical models such as Overlapping Spheres, Sticks or Sticks and Balls in the blender environment.
You might now be thrilled and are ready to start making some nice animations of chemisty in action. But where can you find pdb models to convert? Right here. Check out Malte’s BlenderArtist thread for more info.
I played with this a lot last night. Got a lot of the basic organic molecules I know to work. I had some issues getting some larger molecules like proteins to work (I’m talkin’ 65 KDa here – NF-kappaB’s p65 subunit to be exact if anyone else is interested in trying it). I’ll try to mess with more settings though to see if I can get it to happen.
With the metaball python api, it might be possible to
do some surface representations of molecules too
(e.g., I believe Connolly Surfaces are just glorified
metaball structures). Unfortunately though, metaballs
don’t support different materials per element.
(Might have to bribe Jiri for that one.)

That is a sweet idea Hos. If we could replicate Connolly Surfaces I think a lot of possibilties would open up.
This is a outstanding piece of writing, I discovered your webpage searching bing for a similar subject and came to this. I couldnt come across to much alternative information and facts on this post, so it was pleasant to discover this one. I will likely be back again to check out some other articles that you have another time.
