Some particle experiments

I've been doing some experiments in Maya at work to get a better understanding of nParticles and molecular Maya. The first series involves creating chaotic molecular motion with random collisions. The particles here are not to scale (the water is huge and not plentiful enough) but it serves the desired technical purpose.

I've also been creating an explanatory still image of a bacterial ribosome. A screenshot of the piece in progress is below. You can see that these are large complex structures, and it's been really fun examining the structural data to determine where and how the molecules fit together. Most of that information is embedded in the pdb data, but I had to look elsewhere to see how the growing nascent polypeptide navigates through the exit tunnel. The final piece will show this better I hope. I also didn't have mRNA data, so I generated a RNA-like structure with nParticles converted to geometry.

If you enlarge the image, you can probably see that I'm working with almost 6 million polygons (not by counting; the number is in the upper left). But the viewport (thanks to the Quadro K4000) is still butter smooth, tumbling and zooming.

Later,
