针对移动设备硬件局限性,提出一种新的纹理切片体绘制方案,利用最新支持移动设备的OpenGL ES 2.0接口的图形处理能力,精心地设计体绘制着色程序,完全避免复杂的计算和条件分支,较好地解决了实现医学图像交互式体绘制速度慢的问题.通过在不同的设备上和不同的场景下进行实验,表明本文的方法可以使绘制帧率提高一倍左右.%Hardware limitations for mobile devices,a new texture slice volume rendering method is presented using the graphics processing power of OpenGL ES 2.0 interface which is the latest support for mobile devices presents,painstakingly designing volume rendering shader programs to completely avoid the complex calculations and conditional branching; the problem of medical image interactive volume rendering low speed is sdved.By experiments on the different devices and the different scenarios,show that the proposed method can draw frame rate increased about twice.
