Solid fracture is a common physical phenomenon in the liquid-solid interaction. Thefracturing effects greatly affect the realistic experience of the user in virtual reality, onlinegames, as well as the film industry. In recent years, with the development of computerhardware and fluid animation algorithm, the growing number of the liquid-solidinteraction phenomenon has been very realistic simulation. However, in the field ofcomputer graphics, the real-time simulation of the resulting solid fragmentation in theliquid-solid interaction is difficult to study because of the complicated state of motion aswell as destructive changes. Therefore, due to the traditional boundary handling algorithmfor liquid-solid interaction is complex and is difficult to generate solid fragmentation, wepropose a novel technique to simulate the dynamic effects and richly detailed solidfragmentation in the liquid-solid interaction. The main contributions of this dissertationare outlined as follows:Firstly, based on a Smoothed Particle Hydrodynamics method for the simulation ofboth liquids and solids, our novel method improves the real-time nature of the simulation.Solid particles as part of the liquid particles interact with the liquid. It allows us toimprove the real-time simulation.Secondly, the predictor-corrector scheme is used to simplify the boundary processingalgorithms of liquid-solid interaction. The traditional boundary processing algorithms ofliquid-solid interaction is complex. It is difficult to achieve real-time simulation ofcomplex liquid-solid interaction scenarios. In order to solve this problem, we used thepredictor-corrector scheme for improving SPH algorithm to handle collision between thesolid in the liquid-solid interaction. Thus, we achieved the dynamic interaction of theliquid with the different shapes and different materials of solid.Thirdly, we propose a novel technique for the simulation of the resulting solidfragmentation in liquid-solid interaction. The solid occurred dissolution and fracturebecause of the combined effect of the liquid impact as well as the surrounding solidcollision in the dynamic interaction of the liquid and solid. According to the law ofconservation of energy, we propose a novel technique for the simulation of the resulting solid fragmentation in the liquid-solid interaction. Our novel method allows us to simplifythe real-time fracture as the real-time simulation of fragmentation. The shape matchingalgorithm is used to correctly describe the dynamic interaction of a variety of differentforms of solid. Our novel method reduces the amount of calculation and improves thereal-time simulation, and also it shows the good performance of the details of the fluidpouring, splashing.Finally, we build a liquid-solid interactive3D modeling system and design theexperiments of the solid fragmentation in the liquid-solid interaction. We analyze theexperimental results to verify the superiority of the proposed algorithm. And truereproduction of the common physical phenomena in the life.
