Here is another comparison study for the Advection Stride and Vorticity when set against the Cubic Interpolation parameter.
Quote from the FumeFX 1.2 help file:
Cubic interpolation – If you need maximum quality, you will want to check this option. Simulation times will rise considerably, but less dissipation will occur and more swirls will be created.
- With Cubic Interpolation turned ON and an Advection Stride of 0.01, one can expect very long simulation times.
- Smoke seems to traverse the grid more with Cubic Interpolation OFF.
- Increase in quality is hardly noticeable with Cubic Interpolation ON.
