Rendering Voids in a Molecular Dynamics Simulation

It's been a while since I've posted. I still need to make that post about X-ray scattering but in the mean time, I'd like to share a picture that I helped make. Katherine Sebeck wanted to render the voids in her epoxy simulation in smooth organic way. I generalized the way Kirke handles grids and my metaball code to handle density grids. The density grid for her epoxy simulation was generated from my smoothed meshing code in Kirke. I talk a bit more about it here. I'll show a movie if Katie says it's okay, but for now here is a large picture (~41 MiB):

Glass Made from Mables

This is an old video, probably my earliest video that I can easily find. I made this video using a collection of scripts and maybe a library that would eventually become Kirke. I had just started learning how to use POV-Ray... so about fall 2010. We didn't have a development server and I didn't have my desktop Mastodon. To get POV-ray, I had ask for it to be installed on Nyx. I didn't even have anything cool to make a video of, I had just joined my research group! So I asked Kathrine Sebeck for some of her data.




This is a soda-lime glass molecular dynamics simulation rendered in POV-Ray with ray tracing. Each atom was had a sphere created for it with some size meant to represent the atom size. I have no idea what size I used for each, probably the atomic radius given on Wikipedia. Anyways, each of the spheres was made to look like a glass marble by changing the index of refraction. After rendering each frame, I combined them all using FFmpeg.
