Research: Point Based Graphics

Point-Based Rendering

Efficient point-based rendering methods are investigated in this project. For the interactive display of large 3D point data sets we develop efficient hierarchical multiresolution data structures that support real-time adaptive level-of-detail (LOD) extraction and rendering. To cope with very large data from densely sampled and scanned 3D surfaces, we additionally investigate novel methods for interactive out-of-core visualization of large point sets. To further improve point-based rendering we introduce novel point blending and splatting algorithms such as a single-pass point rendering algorithm that is also the basis for effective rendering of transparent point sampled surfaces.
