What? How? Where?
What? VolViewer is used for viewing volume images from, for example, confocal microscopy or optical projection tomography (OPT).
- Real-time volume rendering using an optimized 3D texture slicing algorithm.
- Interactive transfer functions to independently adjust opacity and intensity for up to three data channels.
- Real-time per channel thresholding, brightness and contrast operators.
- On-the-fly gradient computation for local illumination.
- Iso-surface computation with surface smoothing.
- Section viewing in any orientation / position.
- Real-time volume clipping.
- 3D measurements, filters & segmentation.
- Key frame interpolation for movie export.
- Stereo rendering using either quad buffer or anaglyph mode.
- Scripting interface to other systems, e.g. Matlab, OMERO, etc.
How? It is open source and written in C++ using OpenGL, OpenCL and Qt.
Where? Binaries are available for the Windows, Mac OS X and Linux, see below.
Requirements: An OpenGL 2.1 / GLSL 1.20 compatible GPU with a recomended 512MB of memory.

Although we try to keep up to date builds these sometimes lag behind the SVN trunk. So if you want the latest version / features, it is best to build the application from the trunk of the SVN. The build system is based on qmake for easy cross platform compilation.

Windows Specific Notes
Also note WindowsXP users will need to change the view_gldrawbuffer = "GL_FRONT_AND_BACK" to view_gldrawbuffer = "GL_BACK" in the settings.ini file.
