A measurement platform of soft tissue organ was designed and built, and the stress\u2013strain and stress\u2013relaxation data of pig liver and kidney were experimentally measured. Then, using the viscoelasticity mathematical formula, an improved virtual cutting model of the meshless classified balls-filling was constructed through VC++ and OpenGL. The cutting performance of the virtual soft tissues was further increased by leveraging the improved cutting classification algorithm. Finally, the extrusion and cutting simulation was enabled through the force feedback device, and the accuracy and effectiveness of this cutting model were validated by a comparative study of the virtual soft tissues cutting model and the stress\u2013strain and stress\u2013relaxation data of pig liver and kidney. <\/jats:p>","DOI":"10.1177\/0037549717726144","type":"journal-article","created":{"date-parts":[[2017,8,21]],"date-time":"2017-08-21T13:17:11Z","timestamp":1503321431000},"page":"1073-1085","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":5,"title":["Real-time cutting simulation in virtual reality systems based on the measurement of porcine organs"],"prefix":"10.1177","volume":"93","author":[{"given":"YiDong","family":"Bao","sequence":"first","affiliation":[{"name":"School of Software, Pingdingshan University, P.R.
