Detail-Preserving Shape Deformation in SPH Fluid Control

doi:10.16182/j.issn1004731x.joss.201806046

Abstract

Abstract: It remains a challenging problem to drive particles-based fluid simulation to match target shape and deform fluid shape between different models smoothly in fluid control, especially when the natural fluid motion should be preserved. To achieve the desired behavior, the models are divided into source objects and target objects, and the control particles are generated from them. According to a space point correspondence between source control particles and target control particles, the control particles' movements are calculated which drive fluid to match different models. The control energy from source control particles is transferred to target control particles so as to avoid the leak of control energy and preserving fluid detail. The effectiveness of the method was demonstrated in various scenarios.
