![]() The update focuses on memory optimisation, making Axiom a further “5% more memory efficient”. Updated 12 April 2022: Matt Puchala has released Axiom 2.2. ![]() It’s a performance-focused update, improving overall performance by “10-25%” and introducing 64-bit memory allocation, raising the maximum size of a simulation to 2 billion voxels. Updated 10 January 2022: Matt Puchala has released Axiom 2.1 However, for many users, the biggest change will be that the software is now a commercial plugin, although you can still use it for free in trial mode, or in the non-commercial Houdini Apprentice. According to Puchala, the solver is also now “5% more memory efficient”. ![]() Workflow improvements include control ramps for wind and cooling rate, axis-based control fields, and new Shelf tools and set-ups. However, unlike the CPU-only Sparse Pyro, Axiom is GPU-accelerated via OpenCL, falling back to the CPU if a simulation exceeds GPU memory: each GB of GPU memory is enough for around 8.5 million voxels.Ī ground-up rewrite of the solver – and now a commercial toolĪxiom 2 is a ground-up rewrite of the solver – it isn’t backwards-compatible with previous releases – adding new features throughout the toolset.Ĭhanges include a new Cone source shape for simulations, a new Spin force type for source shapes, support for color dissipation and diffusion, and a new Volume Visualize node. Like the native solver, Axiom is intended to provide near-real-time viewport feedback on complex fire and smoke simulations, speeding up look development. The release also makes the software, which was previously available free, a paid-for plugin, although it is still free for non-commercial use.Ī faster alternative to Houdini’s spare Pyro solver for look developmentįirst released in 2020, Axiom is a GPU-accelerated sparse gaseous fluid solver, intended as a faster alternative to Houdini’s Sparse Pyro solver for look dev work. Version 2 of the solver adds new simulation source types and forces, support for colour dissipation and diffusion, a new Volume Visualize node, and a lot of workflow and performance improvements. Scroll down for news of the Axiom 2.2 update.įormer ILM FX TD Matt Puchala has released Axiom 2, a major new version of the popular GPU-accelerated sparse gaseous fluid solver for simulating effects like smoke and fire inside Houdini.
