摘　　要：本文介绍了我们开发的三维医学图像可视化系统MedVis．绘制的实时性和系统的交互性是设计MedVis的两个重要原则，通过两个核心绘制算法：结合三维硬件纹理映射和Shear－Warp变换的体绘制算法，及多分辨率的等值而抽取算法，达到了良好的交互性，本文介绍了这两个核心绘制算法．该系统较好地解决了体可视化软件中实时性和绘制精度两方面的要求，为医学图像可视化提供了与力的工具．This paper introduces a 3D medical visualization system: MedVis Convenient interactionand real time rendering are two important considerations in system design. Two algorithms are developed: 3D texture mapping and Shear-Warp combined volume rendering, and multiresolution isosurface extraction and rendering. The methods are discussed in detail. The requirements on bothsides of real time and assurance was successfully fulfilled in MedVis. It provides an effective tool forthe application and research in medical field.
