* Solve bug related to corrupted texture tiles for certain sizes. * Regard layer settings when sampling height map. * Make Tile in to a class instead of a struct. * Memory aware lru cache. Needs cleanup. * Clean up and comment. * Clean up and comment. * Clean up * Clean up and comment. * Fix compilation error on Windows. * Specify data type explicitly in GDAL xml config files for Utah height maps. Closes #242 * Update the key type for the memory aware lru cache and use a unordered map instead of a map. * Solve pixel row size bug. * Solve initialization bug. * Add cache size as property of the globe browsing module. * Use memory aware tile cache for text tile provider. * Log GDAL errors as GHOUL messages * Add the ability to toggle tile level limiting by available data * Add ability to toggle GDAL logging * Add lock guard to memory aware tile cache * create base class rawtiledatareader that can be extended with different implementations than GDAL. * Let GdalWrapper take care of global GDAL settings. * Move iodescription to separate file * Move some functionality from gdalrawtiledatareader to rawtiledatareader * Move functionality from gdalrawtiledatareader to rawtiledatareader. * GDAL is no longer a necessary dependency for the globebrowsing module. However to read tiles, the SimpleRawTileDataReader needs to be implemented. Otherwise GDAL is needed. * Add ifdef check for GLOBEBROWSING_USE_GDAL * Implement SimpleRawTileDataReader. Currently can only read pow 2 textures. * Change ints to unsigned long longs * Limit number of texture creations per tile provider per frame * Solve linker error on windows * Fix Windows build errors * Fix crash in reading local patches * Update lodglobe descriptions * Abstract away overviews in gdal raw tile data reader * Update Mars and Moon configs. * Update screenshot script * Update ghoul version * Remove use of interaction depth below ellipsoid * Normalize direction vector * Use scale for distance swotch * Go back to use of interaction depth below ellipsoid * Fix comments on pull request. * TileProviderByLevel error does not propagate up. * Comment on mars and moon mod file * Add model space cut off level as a property * Update ChunkTile struct * Minor clean up * Go back tu constructor for ChunkTile
OpenSpace is an open source, non-commercial, and freely available interactive data visualization software designed to visualize the entire known universe and portray our ongoing efforts to investigate the cosmos. Bringing the latest techniques from data visualization research to the general public, OpenSpace supports interactive presentation of dynamic data from observations, simulations, and space mission planning and operations. The software works on multiple operating systems (Windows, Linux, MacOS) with an extensible architecture powering high resolution tiled displays and planetarium domes, making use of the latest graphic card technologies for rapid data throughput. In addition, OpenSpace enables simultaneous connections across the globe creating opportunity for shared experiences among audiences worldwide.
The project stems from the same academic collaboration between Sweden’s Linköping University (LiU) and the American Museum of Natural History (AMNH) that led to the creation of Uniview and its parent company SCISS. Development of the software began several years ago through a close collaboration with NASA Goddard’s Community Coordinated Modeling Center (CCMC) to model space weather forecasting and continued last year with visualization of NASA’s New Horizons mission to Pluto and ESA’s Rosetta mission. This promising set of preliminary work provided a foundation for recent NASA funding, which has extended the collaboration to include the University of Utah’s Scientific Computing and Imaging (SCI) Institute, New York University’s Tandon School of Engineering, multiple informal science institutions across the United States, and multiple, international vendors. Current areas of focus within OpenSpace include:
- Visualization of dynamic simulations via interactive volumetric rendering, as a priority for communicating research in astrophysics.
- Utilization of NASA’s SPICE observational geometry system with its Planetary Data Service (PDS) to enable space mission visualization that reveal how missions are designed to gather science.
- Globe browsing techniques across spatial and temporal scales to examine scientific campaigns on multiple planets, including close up surface exploration.
This repository contains the source code and example scenes for OpenSpace, but does not contain any data. To build and install the client, we refer to the Wiki pages here on GitHub, specifically building for Windows, Linux, and MacOS. Required preexisting dependencies are: NASM, Boost, and Qt.
