基于计算机图形处理器加速的体绘制

GPU-based Volume Rendering

可编程顶点渲染器和片元渲染器已成为新一代图形处理器(GPU)的标志。应用可编程渲染器带来了许多过去由固定渲染器无法得到的复杂图像效果和三维环境的真实感。图形硬件的可编程能力也扩展了硬件加速的直接体绘制算法,提高了它的交互性能和图像质量。我们充分利用硬件加速支持的三维纹理、片元渲染器,实现了硬件加速的体绘制。

The programmable vertex shader and fragment shader are the sign of the new generation graphic processing unit （GPU） that brings new special effects and increases the quality of image. Also, the programmable graphics hardware expands the algorithms of direct volume rendering; new rendering algorithms based on texture are presented. These algorithms use hardware accelerated 3D texture and fragment shader to implement volume rendering.
