The library will be (mostly) toolkit agnostic but we plan to ship the initial version with a Juce based example UI implementation that will be open source. The library is based on our award winning VoluMedic renderer and we did a quick test implementation in Juce. For the successful compilation of Qt for FW4SPL. Qt is an external library used in FW4SPL.
a Docker container, and want to use gr_volume(), you can use Xvfb or similar tools to start an X server that can be used by GR3.
The choice of using VTK as a visualization library was made after evaluating similar systems. The design is based on the visualization library VTK along with Trolltech Qt, a GUI Toolkit in C++. Sometimes the user wants to identify and represent an organ using an opaque surface in an otherwise partly opaque visualization of the volume data set.
