基于标准PC机的大数据实时体绘制算法研究究

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。

Real-time volume rendering of large datasets on standard PC hardware

A high quality volume rendering technique was presented to render a large volume dataset at interactive rates on standard PC hardware.We employed 3D 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 volume data,and achieved real-time performance without any loss of image quality.
