FIPS — OpenGL based FITS image viewer

FIPS is a cross-platform FITS viewer with responsive user interface. Unlike other FITS viewers FIPS uses GPU hardware via OpenGL to provide usual functionality such as zooming, panning and level adjustments. OpenGL 2.1 and later is supported.

FIPS supports all 2D image formats (except for floating point formats on OpenGL 2.1). FITS image extension has basic limited support.

If you haven’t found your distro above then you can build from sources or contribute building packages for your favourite distro. Let us know to insert missing instructions.

Building from sources

git clone
mkdir -p fips3/build
cd fips3/build
cmake ..

For Windows (make sure you have cmake in your PATH, then run in PowerShell):

$Platform = 'x64' # or 'x86'
$QtDir = 'E:\Libs\Qt\5.14.1\msvc2017_64' # make sure the path and platform is right
$Generator = 'Visual Studio 16 2019'
$Architecture = 'x64' # or Win32
$Configuration = 'Release' # or Debug

$env:PLATFORM = $Platform
$env:QTDIR = $QtDir

$env:PATH = "$QtDir\bin;$env:PATH"
cmake -G"$Generator" -A $Architecture .
cmake --build . --config $Configuration --target PACKAGE
