The Graphics Toolbox (GTB) is a collection of C++ libraries and apps for computer graphics and data visualization.

Wagner Correa initially created GTB as part of his Ph.D. research at Princeton University in collaboration with Professor Claudio Silva and Dr. James Klosowski. Several other researchers later contributed to GTB (see the AUTHORS file).

Features

  • Out-of-core rendering (rendering 3D models larger than main memory)
  • Spatial decomposition (partitioning 3D models using the octree data structure)
  • Simplification (creating approximate 3D models with different levels of detail)
  • Multithreading (using multiple threads for caching and prefetching to hide I/O latency)
  • Visibility algorithms (approximate and conservative occlusion culling)
  • Distributed rendering (using multiple machines to speed up rendering and support larger datasets)
  • Support for point clouds, polygonal models, and volumetric datasets

Project Samples

An exterior view of the UNC power plant (13 million triangles). The Boeing 777 dataset has 352 million triangles (7.5 GB of data). The size of the octree using at most 480,000 vertices per leaf is only 1.2 MB. The Lawrence Livermore National Laboratory isosurface dataset (473 million triangles). Volumetric rendering of freshwater plume during the ebb tide in the Columbia River estuary.
