MantaflowUnified Smoke & Fluid Sim Framework
Rating the current smoke sim 1:10Quote from BA: "personally, i would give it a 5, the smokes are too smooth and it makes it look phony. [...] it should have more natural Brownian motion into it, not just expanding the smoke clouds, but also dispersing " (1832vin)
Small details on surface are possibleSmaller details on surface possible, but I had to crank up the HiRes quite a bit, which is not always feasible.
Common Solution: Textures
New Solution: Vortex Sheets
Left to right: Base sim, small-scale buoyancy effects are calculated using vortex sheet dynamics, details from obstacle interaction, combined

There is more to it...● Simulation on 3D and(!) 2D Grids● Export Surface Meshes for Smoke● Smoke- and Fluid System in one● Multiple Fluid Domains supported● Some functions use CUDA● ...
Manta Demo GUI-Version
Demo Blender Integration...
Why integrate Manta● Stable and expandable framework…● Actually used for research
➢ We might get bleeding-edge features right into B3D● Blender as a GUI and Renderer for the
researchers➢ Mutual benefit?
