cloudfx Posted June 25, 2012 Share Posted June 25, 2012 (edited) I have a particle that is following a curve and tried 2 different vop noise which are : Turbulence Noise VOP Curl Noise VOP to my velocity vector, Turbulence Noise VOP seems to make the particle shake whole body and Curl Noise VOP tends to keep the flow but add a curly noise to the flow. Is that correct? So, what could be a solid differency between , Turbulence Noise VOP Curl Noise VOP Anti-aliased Noise VOP ?

old school Posted June 25, 2012 Share Posted June 25, 2012 Anti-Aliased Noise (of type perlin, simplex, cell, etc) with or without Turbulence (a loop to add successively finer amounts of the same noise for roughness) is noise that generally goes from -1 to 1. Turbulence Noise is generally Anti-Aliased Noise that is folded over (absolute value of anti-aliased noise) and generally goes from 0 to 1. It looks billowy or pillowy. Curl Noise is non-divergent meaning that the noise has no “sinks” or “sources” and gives you a fluid-like motion when applied to particles velocity by itself won't impart any directionality which explains what you are seeing. 1 Quote Link to comment Share on other sites More sharing options...
