fluidSetInterpMethod — Set interpolation method for channel in Fluid Engine
Set interpolation method for channel in Fluid Engine. Lower order interpolation methods will render faster at lower fidelity while higher order interpolation methods will render slower at higher fidelity. Default interpolation for a channel is 4th order interpolation.
ienginenum -- engine number assigned from fluidEngine
ichannelnum -- which channel number to use for the preset in the given fluidEngine
iInterpMethod -- interpolation method, can be any of the following
0 -- No Interpolation
1 -- Linear Interpolation
4 -- 4th Order Interpolation (Default)
7 -- 7th Order Interpolation (Highest)
