  • Real-time volume rendering using an optimized 3D texture algorithm.
  • Interactive transfer functions to independelty adjust opacity and luminance for up to three data channels.
  • Real-time thresholding, brightness and contrast operators.
  • On-the-fly gradient computation for local illumination.
  • Iso-surface computation.
  • Section viewing in any orientation / position.
  • Real-time volume clipping.
  • 3D measurements.
