### SkyViewer: Initial announcement here

Hello,

This is my first posting to these forums. I have just released an update to a program some of you may have seen.

SkyViewer: This is an OpenGL based program to display HEALPix-based skymaps from FITS format files. The loaded skymaps can be viewed either on a 3D sphere or as a Mollweide projection. In either case, realtime panning and zooming are supported, along with rotations for the 3D sphere view, assuming you have a strong enough graphics card. You can also select and display the information for each pixel.

It is written in c++ and uses the Qt widget set for the GUI. I have developed it under Linux, but have only used libraries that claim to work under Windows and OSX as well.

If you try building under Windows or OSX, please let me know how it goes.

This is an active project, so all comments/suggests/problems are most welcome.

Nicholas Phillips

### Bug fix

New version of source at LAMBDA site.
Fixes the compile error:

skyviewer.cpp: In member function virtual void SkyViewer::init()':
skyviewer.cpp:48: error: no matching function for call to SkyViewer::setBackgroundColor(int, int, int)'

Or make the following change:
line 48 of skyviewer.cpp from
setBackgroundColor(0,0,0);
to
setBackgroundColor(QColor(0,0,0));

### SkyViewer: Initial announcement here

I tried to compile it under MAC OS X and it complains about
not being able to find the libQGLViewer.so
I thought it was a problem with the path to libraries, but in fact
the .so file is not generated at all when compiling QGLViewer
for some reason...

any help with this wd be appreciated.
