摘要
三维可视化技术在医学及工业领域应用广泛。文章首先介绍了三维可视化技术的概念,分析了三维可视化技术的原理和关键算法,即面绘制、体绘制、点绘制算法;然后对三维可视化开发包VTK进行了介绍,并以Ray Casting算法为例给出了基于VTK的三维体绘制算法的实现过程;最后对三维可视化技术的发展趋势进行了展望。
Three-dimensional visualization technology is widely used in medicine and industry field.This paper first introduces the concept and the importance of the three-dimensional visualization technology,describing the algorithms of three-dimensional visualization technology in three categories: surface rendering,volume rendering,point rendering.Then the VTK which is a three-dimensional visualization SDK is introduced,and an volume rendering example of Ray Casting algorithm based on VTK is proposed.In the end,the prospective developing direction of the three-dimensional visualization technology is put forward.
