In order to break through the limitation of GPU memory for the traditional
texture_based volume rendering, an effective technique utilizing 3D texture partitioning based
on full binary tree is presented for rendering largescale volume datasets interactively on
general purpose GPU . Using the Fragment Programming capability of commodity graphics cards,
the texture data is transferred to a 1D color lookup table and a working set of dynamic
texture datasets equivalent to the volume dataset size. The working set manages the boundaries
between blocks with the help of abstract partitioning and inherited attributes.The
experimental results show that this method is efficient for rendering largescale volume
datasets at an interactive rate on general purpose PCs．
