Another quick demo of the upcoming 'adaptive domain' for smoke simulations by Miikah.
Testing new adaptive and moving domain features. Simulating this wide scene with the old simulator would have required thousands of cells wide domain. :)
In this case domain is moving with the emitter to clip smoke when it leaves the camera. Domain resolution was 128 with 1x "high res" noise.
The locomotive model was downloaded from BlendSwap.com: "Animated Train" by "kuhn0362".
Note: This is an experimental feature I'm working on as a GSoC 2012 project. Development happens in the "soc-2012-fried_chicken" branch.
