Volume Haptics Toolkit version 1.4 released

See User information
Version 1.4 of the Volume Haptics Toolkit has been released.

The Volume Haptics Toolkit provides an extension of the H3D API into the domain of volumetric data. The toolkit provides the scene-graph nodes needed to generate both advanced haptic feedback from volumetric data and for producing scientific visual rendering. Primarily the haptic algorithms provided by the toolkit are designed to provide natural representations of information from scientific volumetric data and to provide guidance in the exploration process. The methods are, however, very general and can also be used for other purposes, for example to generate guidance fields in games or alternative tasks, or some surgery simulation.

From the release notes:

The primary change in this release is the handling of the transfer functions for colours. An abstract colour transfer function type is introduced that can either be defined by combining three ordinary transfer functions, or implemented as a special colour look-up or so. Observe that the visualization components now use this interface and so you will have to update your code if you use any of these. There is also some new features in the volume haptics components. For example there is a means for adding visual representations of the currently active haptic primitives, and support for haptic shading, i.e. modification of the haptic pipe-line.
