version 0.3.0 release

version 0.3.0 - 20190821

• Added sampler with a variety of data-space sampling algorithms:
  • metropolis-hastings sampling as a multiserver tool
  • ray-based sampling using the 'Sampler' infrastructure
    • Sampler is a subclass of Renderer that supports integration with active-Vis operators
    • active-Vis operators to implement sampling based on isosurface crossing and significant changes to gradient
  • interpolation of a scalar field onto a set of samples (as a multiserver tool)
• Support for vector-valued volumes
  • added JSON format for volume description files that implements 'number of components' field
• Initial implementation of RungeKutta operator to trace streamlines in vector volumes
  • also 'TraceToPathLines' opewrtor to convert RungeKutta results to path lines for rendering
• Added schlieren to provide multi-hued Schlieren and shadowgraph-style rendering
  • also implemented 'float-image' output (in FITS format)
• Added ospray modules for class overrides to the underlying OSPRay rendering engine
• Separated data-generation and data-management tools into data from apps
• Added Docker containers:
  • galaxy: contains pre-built version of galaxy in CentOS linux
  • galaxy-base: contains pre-requisites for galaxy build in CentOS linux
• Added unit testing framework
• Renamed async app and associated source to gxyviewer
• Renamed vis app and associated source to gxywriter
• Renamed mh app and associated source to mhwriter
• Renamed amh app and associated source to mhviewer
• updated third-party/ispc to download v1.10.0
• updated third-party/embree to use v3.5.2

version 0.2.1 release

version 0.2.1 - 20190325

• Moved Doxygen to root Galaxy directory
• Fixed includes for Fedora 29 build

version 0.2.0 release

version 0.2.0 - 20190208

Refactorization of Galaxy core to cleanly partition framework, data, and renderer layers. Initial release of multiserver modularization of Galaxy framework.

• Added new multiserver component that enables Galaxy to live as a service (e.g. alongside a simulation in situ) and process requests that arrive via remote connections.
• Removed OSPRay and Embree dependencies from framework and data layers.
• Install now generates a GalaxyConfig.cmake file so that Galaxy components can be included in other programs
• Added Travis-CI build and test integration
• Added sanity-check gold image tests in tests
• Added Galaxy state file documentation in doc/configuration_files.md
• Added Python as a prerequisite for testing and use of python scripts in scripts
