    • a Qt-based node editor4 graphical user interface for Galaxy workflows
    • added nodeeditor submodule
    • added Qt5 dependency
  • Added insitu socket connectivity for in situ workflows
  • Added tracer streamline generation and rendering
  • Added sampler methods
    • Gradient-based sampling
    • Isovalue-based sampling
  • Added demonstration codes for new features in apps
  • Updated to python3
    • python scripts
    • travis-ci config
    • travis-ci VTK-8.1 build

version 0.3.2 - 20191212

  • updated OSPRay version to 1.8.5
  • updated Embree version to 3.6.1
  • updated ISPC version to 1.12.0
  • centralized third-party installation to third-party/install directory
  • removed patchfiles for third-party packages, moved config options to cmake arguments in scripts/install-third-party.sh

version 0.3.1 - 20190930

  • added examples for Schlieren renderer in examples/schlieren
  • added examples for various data samplers in examples/sampletrace
  • added second, energy-accumulation schlieren algorithm
  • added 'data.state' argument to sampletrace to track data
  • moved image resolution specification to Camera
  • added Cinema database example of Water in the Universe data in examples/WitU
  • added 'data range' to visualizations to select range of interest

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' operator 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
  • updated third-party/ospray to use v1.7.3

version 0.2.1 - 20190325

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

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

version 0.1.0 - 20181005

Initial Galaxy release!

  • Asynchronous tasking and communication framework
  • Data layer for visualization and rendering
  • Distributed ray tracing renderer built on Intel OSPRay and Embree for volume integration and geometry intersection, respectively
  • Doxygen-based documentation of classes
  • CMake build and packaging
