Dendritic Cell

Posted in Cinema 4D, Experimental, Medical Animation by Joel Dubin on February 28, 2010

It’s late night Saturday night, which means its time to rev up Cinema 4D and see what I can do with it. Found this old model of a Dendritic cell from an old project. Dendritic cells are a component of the human immune system. I took the base model (shown below) displaced and smoothed a bit, then cloned the little white spheres (representing the antigens the cell presents to other immune cells) via the Mograph cloner object. A little subsurface scattering, transparency, ambient occlusion and the ever-present medical animation “floaties” and I’m beginning to get something interesting.

The low-res, untextured base model was built in Maya by another 3D artist, and then exported for use in Cinema 4D. Below is the low res model we started with.

Below are a few Dendritic Cell images found on the web which were used as reference:

Thanks for looking!

Micro Crystals

Posted in Cinema 4D, Experimental, Medical Animation by Joel Dubin on February 27, 2010

Here’s an image that began as an experiment in Cinema 4D. It was included recently in an earlier post on my blog.

The result begins to resemble a macro shot of ice crystals, or some other crystalline formation. I really liked how the original image above turned out, which was created about a year or 2 ago, and always intended to explore what more could be done with it. I just recently re-discoverd the file, and finally had the chance to experiment with it some more; the result being this short animation clip.

The entire model is parametric, generated from a simple plane whose faces are randomly extruded via the MOGRAPH EXTRUDE object and altered with the RANDOM EFFECTOR, with visibility being the only parameter checked. The MOGRAPH DISPLACER DEFORMER was applied and then additional displacement was added in the shader. I also used the Transluscent Pro plugin shader for quick subsurface scatterring (transparency is actually inactive here). You can see the general workflow in the image below.
If time allows, I hope to do a more in-depth tutorial soon.

Pack Shots

Posted in 3D Models, Cinema 4D, Package shots by Joel Dubin on February 20, 2010

Here are some product shots I put together in Cinema 4D. This one was for the heart medication Plavix. I created the animated end tag for the ad spot first and then was asked to create the print ad. It ran in Time magazine in 09, which I suppose was cool.

Medication that prevents dogs from vomiting. These are shots from the animation. Two versions.

Another for a “botox-like” drug, also from an animation.

Bone World

Posted in Cinema 4D, Experimental, Medical Animation by Joel Dubin on February 18, 2010

Heres another set of images created in Cinema 4D derived from what was essentially an idea to create bone matrix at a microscopic level a few years ago.

What you see here is what you get when you throw a wavy spline into a cloner, and then the cloner into a metaball object. Sub-poly displacement and ambient occlusion help create bumpy pock marked surface. Environmental fog and depth of field help to give a sense of scale and distance.

The result is looking more like a rocky, or bark-like terrain moreso than bone, but thought it was cool. Another happy surprise from C4d.

White Junk

Posted in Cinema 4D, Experimental by Joel Dubin on February 18, 2010

Some of the things I really love about Cinema 4D are the procedural nature of many of the tools, and the complex results one can achieve when starting with very simple geometry. Below is a simple landscape primitive whacked out with a twist deformer. Some hypernurbs smoothing and ambient occlusion and it begins to look really interesting.

Shots from recent projects (and an experiment or two)

Posted in Cinema 4D, Medical Animation by Joel Dubin on February 8, 2010

Going through my hard drive and found some images from some recent projects that I thought I’d share. All created in Cinema 4D for various medical animation shows. 

UPDATE: I replaced an older  version of the receptor image with a newer shot (below)

More Sciency Stuff

Posted in After Effects, Cinema 4D, Medical Animation by Joel Dubin on February 3, 2010

Finishing up a 10 minute long animation about how too much cholesterol in the blood stream can eventually lead to atherosclerosis (plaque-clogged hardened arteries). Thought I’d share a short shot of a macrophage entering the space just outside of a damaged vessel where plaque is beginning to form. I’m using some similar techniques as used in a previous post, ie: Cinema 4D deformers used to squish the cell as it enters the space.

Composited the depth pass and AO pass separately in AE. Used Frischluft Lenscare for the DOF and RSMB for, well, motion blur. This stuff grosses my wife out, but I have fun with it.
