In the last years the increasing programmability of GPU lead to lots of point-based rendering could be implemented on GPU, which not only let CPU to be available for other tasks, but also improve the execution speed through GPU. However, since the recent GPU does not support the epsilon-z-buffering algorithm, a majority of GPU based rendering algorithms are based on multi-pass rendering to achieve...
We present the I3DC system prototype, which constructs the cube for tens of millions of data items within milliseconds, and provides high-quality cube visualization as well as highly-interactive OLAP operations. Our approach is based on a novel blending-as-aggregation (BAA) algorithm that maps distributive OLAP aggregations to the intrinsic rendering mechanisms of the GPU. Our system runs entirely...
In this paper, we give a view-dependent large-scale terrain rendering method using strip masks of terrain blocks, and our method is adaptive rendering method. Firstly, we partition our terrain into several blocks, and then we pre-compute a set of strip masks of blocks. At run time, in order to render the terrain, we simply choose the mask of blocks that represent each part of the terrain to meet our...
