"Gasoline Fire" - Pyro simulation in Houdini w/ Axiom plugin

For my first attempt at a pyro simulation in Houdini I wanted to try the well talked about plugin called Axiom which makes pyro easier and more streamlined.

Simulation was based on the Axiom solver workflow using their nodes, such as Axiom Solver and Axiom Source Shape. I created one primary source emitter with all settings applied that I wanted, which was then scattered to points each frame with a for each loop setup. With a bounding box I cut out all particles not visible in the camera to optimize calculation time. Rendering and shading was done in Karma and was really quick. Final render time was around 2 hours for a 10 second sequence, 256 samples in 1920x1080.
