And another thing exciting about Cinema 4D that I'll demonstrate, how we can apply this again is the robust physics that have been available since version 12 several years ago. So this is showing a bit of DNA, much more recognizable molecule than the other lumpy shapes that I've been showing. And then of course I've used it in many cases just for illustrating covers to try and engage audiences to get excited about these topics. So it really enables communication as well as data visualization. Again, we use the Cinema 4D for data visualization because when you have features like global illumination, ambient occlusion you can make much more sense out of the relationship of this little pink, pie-shaped molecule to this little blue guy than you can if you don't have those nice lighting effects. And it collects data from available databases of what these structures actually look like, brings them directly into Cinema 4D so you can manipulate them using the tools of Cinema 4D. This was developed by a friend of mine, Ludovic Autin, when I was in graduate school. So these are generated using a tool we developed called the embedded Python Molecular Viewer that's primarily what I'm going to demonstrate today. And then a lot of what we do is editorial art. But because you also have access to powerful simulation tools, both physics simulators as well as Python scripting, you can generate scientifically accurate visualizations. So character animation tools available in Cinema 4D really lend themselves to generating these types of animations. And they're pretty fascinating because, sorry I've got to turn the sound off here, because these proteins behave with very mechanical like systems. And I've done a few animations of proteins walking along surfaces carrying huge cargos. So these are some of the early pieces I did back in the early '90s up here showing a molecule that pumps these little yellow hydrogen cubes into the inside surface of this otherwise impenetrable gray barrier here. I have primarily used it as a teaching tool. And another reason I like to show this is because I've used Cinema 4D not just for illustration, animation, teaching, etc., but also as a direct data visualization tool to confirm, validate and do some analysis on our models. By combining structures of molecues, the larger surfaces that, those molecules fit into with information from biochemistry and biophysics to generate these complex models on the right. And the main reason for doing that biologically was to take this to an extreme where we could do things like model complex viruses like the human immunodeficiency virus, HIV, shown on the right. Since that time, I've gone back to get a PhD in biophysics, and my main project was to build packing software that enables us to take a lot of small objects and pack them into volumes while obeying particular constraints. And those were all key things in my workflow. It was incredibly easy to use and to switch too and very stable. It's a beautiful program, very elegant, but as it started to add functionality it became less and less stable in the late '90s. And I started using one of the first desktop consumer level packages available on a Mac called Strata StudioPro. During my thesis, I got into 3D by reading lots of books, and I built a plastic frog dissection kit so I had early exposure to 3D printing, which was a lot of fun. So these are mixed media representations of surgical illustrations, where we actually got to go into the surgical operating room to sketch over a period of months to create these teaching pieces for residents to learn how to do these particular surgeries. At that time, we were still using traditional media. Where I went to school to get a Master's Degree in medical illustration, and these are images from my work at Johns Hopkins back in the mid '90s. And I'm going to describe a little bit about our unusual background. I am the scientific director of The Vessel Team. If any of you saw Thomas' talk previously, we work together. Well, all right, without further ado, we've got Graham Johnson. ![]()
