Turbulence synthesis for shape‐controllable smoke animation
Ben Qiang Yang, Xiaogang Jin · Computer Animation and Virtual Worlds · 2014
ABSTRACT We present a novel procedural synthesis method to improve small‐scale turbulence details for controllable smoke animation constrained by shapes and paths. In order to enhance fluid details without introducing unpleasing fluid control effects, we propose a spatial–temporal varying synthesis parameter to control turbulence behaviors and compute it from control force and the vorticity velocity. Our approach can control enhanced turbulence behaviors efficiently and produces visually plausible realistic fine‐scale details while reducing artifacts of large‐scale noises on fluid control. We compare our algorithm to existing procedural synthesis ones to validate its efficiency and controllability. Copyright © 2014 John Wiley & Sons, Ltd.
