Volume Rendering, Render-To-Texture, Frame Buffer Object


Volume rendering is a useful method to visualize scientific simulation and medical data. However, it is a time-consuming rendering process. To achieve smooth interaction, many accelerative methods have been proposed. In this paper, we propose a two-pass rendering method based on the concept of shrinking rendering area. We also apply new features provided by the latest graphics hardware, such as render-to-texture (RTT) and frame buffer object (FBO), to achieve optimized performance. Eventually, we measure four different cases and offer some preferential settings when using this technique.
