Research On Techniques Of Haptic Rendering For Mixing Fluid And Its Coupling With Solid

Haptic interaction,including haptic rendering of solid,haptic rendering between solid and fluid,has always been a hot topic in the computer graphics over decades.However,existing study lack methods for the haptic interaction between the mixing fluid and solids.Haptic interaction between mixing fluid and solid has high value in VR games,virtual simulation and other fields.At present,there are a few methods to simulate the haptic interaction between mixing fluid and solid,but those methods still have some problems,such as low accuracy and low stability.Especially in the process of fluid mixing,those problems are more prominent.Our paper presents a new haptic rendering method between mixing fluid and solid.Our method has a certain increase in the stability and authenticity.In order to solve the unstable phenomena,our paper uses a new method to calculate the haptic force so as to solve the unstable.Besides,there are many factors affecting the haptic force.However,the traditional method only consider the pressure and viscous force.In order to improve the authenticity,our paper adds buoyancy and friction calculation to haptic rendering.Efficiency is another factor which affects haptic rendering.The traditional methods simulate the haptic rendering of single-phase fluid,which lead to the problem of inefficiency.However,when these methods are extended to the mixing fluid,the inefficiency is more obvious.In order to solve those problems,our paper presents a new model to calculate haptic force between mixing fluid and solid.The solid is modeled by the FEM method and the mixing fluid is modeled by the SPH method.The SPH-FEM model is used to calculate the haptic force.Our method reduces the computation and improves the users' experience.
