....2. Previous Work Methods to visualize volume data, primarily isosurface extraction [3] 13] 17] and direct volume rendering (DVR) 16] 3] 17] have been extensively studied. Recent developments have produced efficient data structures and algorithms for rendering time series volume data [1][7]. However, we are unaware of other work extending volume visualization methods to 4D medical data sets. By contrast, several 4D visualization techniques have been developed for flow visualization. These include glyphs, streamlines timelines, texture advection, and line integral convolution ....

....using one of many approaches (e.g. ray casting or splatting) Current research in direct volume rendering focuses on improving both image quality and rendering speed. In addition, recent attempts have been made to find efficient data structures and algorithms for rendering time series volume data [1, 4]. 3. Flow Visualization Although time series data is sometimes considered in volume graphics, most research in this area comes from computational fluid dynamics, where various techniques have been developed to visualize flow of liquids and gasses. Glyphs are small pointed objects (e.g. arrows) ....

....view point and the center of focus, and their projected angles. Weiler et al. 5] proposed a level of detail rendering method using a similar data structure with a guarantee of consistent interpolation between different resolution levels. Finally, Ellsworth et al..use a Time Space Partitioning Tree [6, 7] with OpenGL texture object optimization and fast color metric approximations to accelerate time varying volume rendering. While all these techniques allow user control to trade image quality for speed, the relations between the control parameters and the rendering speed are not known. As a ....
....is used to represent the corresponding subvolume. Otherwise, the traversal of the octree continues. If a leaf node is reached, the original data in the subvolume are used. To perform the rendering, we use a simple 3D texture hardware acceleration technique proposed by Ellsworth, Chiang, and Shen [7]. This method uses a polygon slicing and 3D texture mapping technique and breaks the volume into small blocks as the result of octree traversal. If an internal node is selected, flat shaded polygons are drawn. Otherwise, slicing polygons within the volume blocks are rendered and mapped with 3D ....
