用于实时变形的解剖学人体肌肉建模

多层次人体建模方法利用解剖学原理构造虚拟人，将人体模型分为骨骼层、肌肉层和皮肤层等层次，其中人体肌肉层是影响人体表面状态与变形的重要结构。本文提出了一种基于解剖学的人体肌肉层建模和变形的方法，建模方法考虑了解剖学方面的准确性并适合实时变形模拟。肌肉模型的变形采用轴变形技术与横截面变形相结合的变形方法实现。同时介绍了我们的建模工具，建模人员使用建模工具可方便地构造和编辑人体各部位复杂的肌肉体。模型可以根据建模人员不同的需要，在逼真程度和变形速度上取得满意的折中。实验表明，这是一种有效的建模方法，应用到我们的人体建模系统中取得了良好的效果。此方法也可应用于其它软组织的建模中。

Human Musculature Modeling for Real-time Deformation

Human musculature is an important structure for appearance of body surface and its deformation. In this paper, we propose a new muscle model based on both anatomical and real-time consideration. Muscles can be constructed and edited easily by the tool after user appointed some radial and transverse cross-section control parameters. Deformation can be achieved by axial-deformation combined with cross-section. Further more, we introduce our tools for modeling the model. User can adjust the precision of model to meet different requirements. The effects are satisfying when we apply the model to our human modeling system. The approach of modeling can also be used to model other soft tissues.
