I am attempting to prototype a real-time marine data viewing and mapping
application using (right now) C++ and QT. I need to make maps in real
time, zoom in/out, pan around etc, and update the positions of moving
objects, such as navigated ROVs and other instruments.
I am quite comfortable handling map projections, coordinate systems and
transformations, etc, but am not looking forward to the drudgery of
implementing drawing and "pretty" labelling of coordinate axes,
graticules, etc.
I am willing to work in any of the available drawing systems within QT,
including OpenGL, or QT's canvas system--but would really appreciate
pointers to software which can do the 2d (or 3-d) intermediate level
graphics for me. I really want an API, and not a packaged system--our
needs are continually changing, and attempting to use packaged "binary"
systems like Arcview usually fails. I am most interested in cross
platform, but I am generally platform-agnostic--linux, Win32, it doesn't
really matter to me. Open source would be best, but is not a hard
requirement. Nor am I really focussed on QT--if there's a better cross
platform GUI toolkit, I'd use that too
thanks in advance for any help
