The author first proposes an improved mass - spring model developed for rectangle meshes based on the survey of cloth modeling methods , by which the simulation of cloth is formulated unifiedly . the dynamic system of modeling and simulation is derived and solved using time differentiate method , with given composition and expression of internal and external cloth forces in the formulation 在此基礎(chǔ)上作者提出改進(jìn)的基于矩形域的質(zhì)點(diǎn)-彈簧模型,利用該模型統(tǒng)一建立了布料真實(shí)感模擬方程,給出方程中質(zhì)點(diǎn)所受內(nèi)力和外力的組成與表達(dá)式以及動(dòng)態(tài)系統(tǒng)的推導(dǎo)和求解過(guò)程,并且描述了模擬的具體實(shí)現(xiàn)算法。
