Application of STK Model in VRML Technology 关于在VRML技术中应用STK模型的研究
According to the model and shortages of the current remote education, this paper analyses the technical qualities of the virtual reality model language VRML and gives a practical method about designing an educational courseware based on VRML in the modern remote education system. 针对目前现代远程教育的模式和不足,分析了虚拟现实建模语言VRML的技术特性,给出了在现代远程教学系统中建立VRML教学课件的具体方法。
This paper states the way to reconstruct human skeleton model by VRML technologies. It consides human's limb's as simple and abstract rigid geometric bodies based on human body's arthrosis construction. 依据人体的关节连接体层次结构,将各肢体抽象为简单的刚性几何实体,并运用VRML构建了人体骨骼模型的样本。
Because each model in VRML is created in local coordinate system, inconvenient to handle them uniformly, this paper infers a universal formula to transform model coordinates from UCS to WCS. 针对各VRML造型在其局部坐标系中创建,采用变换矩阵实现了造型从局部坐标系下到世界坐标系下的坐标变换。
For the key question of the virtual model replace solid model, this paper discusses method of measurement of virtual model based on VRML and key technology for realization. 为拓展现有VRML模型库的使用功能,研究了基于VRML的虚拟模型尺寸的测量方法和实现技术。
