Adaptive Treelet Meshes for Efficient Streak-Surface Visualization on the GPU
نویسندگان
چکیده
We describe a novel adaptive mesh representation for streak-surfaces. The surface is represented as a mesh of small trees of initial depth zero (treelets). This mesh representation allows for efficient integration, refinement, coarsening and appending of surface patches utilizing the computational capacities of modern GPUs. Integration, refinement, and rendering are strictly separated into effectively parallelizable substeps of the streak-surface integration algorithm. We also describe a sampler framework which unifies the handling of different vector field representations.

متن کاملInteractive Visual Exploration of Unsteady 3D Flows
In this paper we present GPU-based techniques for the interactive visualization of large unsteady 3D flow fields on uniform grids. We propose a novel dual-core approach to asynchronously stream such fields from the CPU, thus enabling the efficient exploration of large time-resolved sequences. This approach decouples visualization from data handling, resulting in interactive frame rates. Built u...

In this paper we introduce an efficient view dependent refinement technique well-suited to adaptive visualization of 3D triangle meshes on a graphic terminal. Our main goal is the design of fast and robust smooth surface reconstruction from coarse meshes. We demonstrate that the √ 3 subdivision operator recently introduced by Kobbelt offers many benefits, including view-dependent refinement, re...
