摘要
为了解决在标准PC机上对大数据进行实时体绘制的问题,提出了一种基于图形处理器的大数据高质量体绘制算法。该算法采用三维纹理映射作为核心的绘制算法,结合可见性测试、遮挡测试和模板测试来加快绘制速度。实验结果表明,对虚拟人体数据,可以在不损失图像质量的前提下,以可交互的速度进行绘制。
A high quality volume rendering technique was presented to render a large volume dataset at interactive rates on standard PC hardware. We employed 3 D texture mapping as a core rendering engine and ＇took advantage of combinations of HW-supported visibility tests such as occlusion queries, stencil tests and programmable shaders to accelerate the whole rendering process. We have implemented the volume rendering algorithm for large voltm^e data, and achieved real-time performance without any loss of image quality.
