我们提出了一种利用图形处理器单元 (GPU) 的强大功能以及 Marching Cube (MC) 算法来加速等值面多边形化的新颖方法。在我们的方法中有效使用 GPU 使我们能够加速输入数据集的整个立方体的立方体索引计算,这是 MC 中的主要过程。我们的方法非常独特,因为它生成用于像素着色硬件中数据集的几何构造的信息。我们的方法中的技术类似于多通道方法中的技术,因为多个渲染通道用于渲染最终图像。然后,在我们的方法中,前一个通道的结果被输入到几何管道中,而在多通道方法中,它被输入到图像管道中。我们的实验结果很好地说明了我们的方法对于实时生成的体积数据(例如元球和数值模拟结果)有许多应用,而无需对输入数据集施加任何条件。
We present a novel approach to accelerating isosurface polygonization by exploiting the power of graphics processor unit (GPU), along with the Marching Cube (MC) algorithm. Efficient use of GPU in our approach allows us to accelerate cube index computation for the entire cubes of input data set, which is the dominant process in MC. Our approach is quite unique in that it generates information for geometric construction of the data set in pixel shading hardware. The techniques in our approach are similar to those in a multipass method in that the multiple rendering passes are used to render the final image. Then the result of previous pass is fed into geometry pipeline in our approach, whereas it is fed into an image pipeline in the multipass method. Our experimental results illustrate very well that our approach has many applications for realtime generated volume data such as metaballs and numerical simulation results, without imposing any conditions on the input data set.
