Efficient method for point-based rendering on GPUs

We describe methods for high-perfomance and high-quality rendering of point models, including advanced shading, anti-aliasing, and transparency. we keep the rendering quality as the previous GPU-based point rendering approaches, while involving normal vector computation for each frame. We also present efficient data structures for hierarchical rendering on modern graphics processors (GPUs). In addition we will address methods for geometric processing, filtering and resampling of point models. Examples are presented to illustrate the quality of the meshes produced, and the flexibilities of the computational system.
