VolViewer is an open source application for the interactive visualisation and quantification of biological data. The application is written in C++ using OpenGL and Qt.


  • Real-time volume rendering using an optimized 3D texture slicing algorithm.
  • Interactive transfer functions to independelty adjust opacity and luminance 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.


Nvidia Geforce 8 and above.
