3D visualization and information interaction in biomedical applications

Abstract

针对生物医学工程研究对象几何形状不规则、材料复杂等特点 ,提出并实现了基于多边形描述的分层次绘制的生物医学系统模型三维仿真显示和基于 Open GL 选择模式的信息交互的软件方法。软件实现了三维模型的建立、随动几何变换和信息交互以及对常用商业有限元软件包数据文件的识别等功能。软件技术先进、界面友好、交互性强、使用方便 ,并具有良好的可扩展性和可移植性 ,为生物医学工程领域三维拟实仿真建立了一个优良的计算机图形学平台 D visualization and virtual reality are important trend in the development of modern science and technology, and as well in the studies on biomedical engineering. This paper presents a computer procedure developed for 3D visualization in biomedical applications. The biomedical models are constructed in slice sequences based on polygon cells and information interaction is realized on the basis of OpenGL selection mode in particular consideration of the specialities in this field such as irregularity in geometry and complexity in material etc. The software developed has functions of 3D model construction and visualization,real time modeling transformation, information interaction and so on. It could serve as useful platform for 3D visualization in biomedical engineering research.
