Abstract

The invention discloses a multi-particle hybrid modified thrombus simulation method based on a Cross model. A multi-particle hybrid modified SPH method based on the Cross model is utilized to simulatethe blood, so a problem that the phenomenon that large-mass particles sinks downwards and small-mass particles rise upwards in the simulation process does not conform to the normal blood physiological phenomenon is solved, a particle-by-particle polymerization method is utilized to simplify a thrombus model to simulate thrombus formation, and a problem that a traditional method can not simulate thrombus formation of the blood is solved. The method is advantaged in that the blood can be more realistically simulated, and thrombus formation of the blood can be further simulated. Through correctly simulating thrombus formation, the thrombus study is facilitated, the method can be applied to medical applications such as virtual surgery and medical assistant research, moreover, needs of relatedaspects in game and film industries can be satisfied.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a thrombus simulation method based on Cross model-based multi-particle mixed correction. Background technique [0002] Blood is a tissue that is propelled by the heart and circulates in blood vessels throughout the body. It has the functions of transportation, defense, temperature regulation, and maintenance of acid-base balance and osmotic pressure balance, and plays a vital role in maintaining human life and health. Thrombosis is the coagulation of blood for some reason, and diseases caused by thrombus may pose a huge threat to human life and health. [0003] Fluid is a general term for gas and liquid, and it runs through all aspects of human life. How to efficiently simulate fluid animations on computers that conform to the properties and laws of motion of real fluids has become a very hot topic in the field of computer graphics in recent years. The methods of computer fluid ...
