A bleeding simulation algorithm for skin surface based on improved SPH method
Translated Abstract
Aiming at low dynamic model precision problem of the current blood flow realistic graphics rendering meth-ods,a bleeding simulation algorithm for skin surface based on improved SPH method was proposed.First,some blood flow simulation algorithms were analyzed and the Casson model was selected as the fluid dynamics model of blood flow.Second,according to the characteristics of the dynamic equation of Casson fluid,the traditional SPH method was improved.Third,the improved method was used to calculate the blood flow.Finally,the obtained blood particle kine-matics information was used to simulate the flow of the skin surface.The experimental results showed that the improved SPH method could reduce the complexity of the traditional method and improve the accuracy of the program,which would provide a new method for the skin incision bleeding simulation in virtual surgery.
