Intersecting and visibility ordering are key problems that affect the efficiency of volume rendering, especially when the grid of data field is irregular. In this paper, a partition approach for direct volume rendering the irregular 3D data field is given. In this approach, the image plane is partitioned and the current boundary cell set is divided correspondingly. By exploiting the characteristic of adjacency, the efficiency of intersecting is increased, therefore the rendering speeds up. The implementation of the approach, together with some results is given in this paper.
