Hi all, for the last couple of weeks I've been working on this scientifically
accurate image depicting spatial relationships between the three critical
proteins that comprise the human heart's molecular motor.
This image is currently a candidate for the September 2012 cover of the journal
Science (fingers crossed).
Here are the four render passes that I used for this shot: ambient occlusion,
subsurface translucency, Z-depth (for faux focal blur), and a standard radiosity
render, along with the final composite of all four render passes.
The red, green, and yellow/orange bits are all blobs. The springy orange
connectors and big blue "heads" were modeled in Wings3d. The spaghettified tubes
are random parametric sphere sweep meshes built by a POV-Ray macro and written
to disc (and render oh-so-much faster than actual sphere_sweeps). The background
is a height field made up of several of my old images all mashed together and
rendered, then blurred mercilessly with Photoshop in the final comp.
Cheers,
Rob

I noticed that the large compound image is too large to show up in the web
newreader for some reason, so here are just the render passes.

looks much better than a B&W electron microscope shot. :)

Thanks! I love those electron microscopy images, but apparently even our
strongest devices aren't yet strong enough to reveal anything close to this
level of detail (which is why I was recruited to do this shot ;)

Amazing... and it could do as Friday Abstract, too. ;)
My only "complaint" is that my brain expects more focal blur there,
perhaps because I know the scale is very small.

Great image, I especially like the green whatever-that-is-helix.
I'll be sure to check the cover when visiting the library ;)
The only thing I wondered is if the illumination might be too bland.
As far as I understand the process it is perfectly diffuse AO/radiosity
(is the model itself emissive?). Some harder shadows might increase the
perception of depth and 3d structure. Especially the blue "heads" feel
a bit surreal to me (which can of course be a good thing, too).
I realize of course that actual light would just diffract like hell
instead of giving any sort of shadow, but then actual light wouldn't
give you this image anyway ;)

More than excellent indeed. I hope this image will make it to the
Science cover.

Maybe one small comment: those yellow objects all seem to twist in an
identical way. Is this intentional or is it just the result of instancing?

Thank you, sir :)
I agree that the focal blur should probably be much greater, but I kept it
subtle; the researchers wanted the structure of the proteins to not "get lost."
