基于VTK的陶瓷材料显微结构的三维可视化研究

Study on the three-dimensional visualization of ceramic microstructure by VTK

在陶瓷材料微观结构的研究中,传统方法通过在显微镜下观察样本的二维截面图像来进行研究,难以直观地认识三维显微结构.本文提出了一种对显微结构进行三维可视化的研究方法.在VC++6.0平台下,结合三维可视化工具VTK,显示了显微结构的形态和空间分布,并进行平移、旋转和缩放等实时交互操作.通过建立坐标系,对三维空间物体的长度进行测量.实验结果表明:此方法能直观、准确地反映陶瓷材料的显微结构,并能获取尺寸大小等定量信息.

In the research of ceramic microstructure,traditional method studying microstructure by observing two-dimensional sections of a sample under microscope is difficult to intuitively understand the three-dimensional microstructure.This paper presents a method to study the ceramic microstructure by three-dimensional visualization.The microstructure was visualized using VC＋＋6.0 with visualization toolkit VTK.Microstructural morphology and spatial distribution was revealed.Real-time interaction such as translation,rotation and scaling operation was conducted.The length of three-dimensional object was measured after the establishment of coordinate system.Experimental results show that this method can be used to observe ceramic microstructure and obtain quantitative information such as size.
