Image of a Thermomnuclear Supernova Progentior

Holy cow, it's been a long time since I blogged.

The class I'm teaching right now is 3d Computer Modelling and Animation. Perhaps the hardest thing about it is figuring out if the word Modelling has one or two l's in it... it depends on whether you're in the USA or Canada, I think.

For this class, I'm making all of the students do a major project. Some of them are doing some pretty interesting things, and already several of them have figured out things about Blender (the 3D software we're using, a quite powerful free package that you should check out yourself) that I don't know myself. A couple are playing around with motion tracking, in order to add 3D rendered elements into a live action video scene. One is building a game using the Blender game engine. Others are doing various other animations.

I've decided to take on a project myself. For this project, I am going to model a white dwarf in a mutual orbit with a main sequence or red giant star, pulling matter off of it into an accretion disk. During the animation, the white dwarf will go critical, and explode in a supernova, blowing itself way, and blowing off some of the outer layers of the companion star.

So far, I've managed to create the basic progenitor model, and do a little bit of animation of the textures so that the disk is spinning, the star's surface is roiling, and the gas bridge between the star and the disk looks a little like it's streaming. Here's a rendered frame from what I've done so far:

I'll certainly post the full animation once I've completed it. Next, I'm going to have to start worrying about how to deal with the supernova. Eventually, I'll set the whole thing to music.
