Support
Code repositoryVolumetric data is often the natural format to use for various purposes in scientific and engineering visualization process. This is often due to how data is collected from such equipment.
One example is seismic data from measurements below the sea- floor, as done in the oil & gas industry to locate pockets of hydrocarbons. Another example is medical scanning equipment, from sources such as Nuclear Magnetic Resonance (NMR/MR), Computer Tomography (CT) and ultrasound. These data collection methods gathers data in the form of point measurements, which does not always lend itself well to visualization in the form of polygon primitives.
SIM Voleon provides the technology to render such volumetric data sets, to modify their color mappings and transparency settings to e.g. visualize internal structures, to interact with the data (for querying positions and data values), and to integrate volume data with the traditional polygon-based geometric primitives of the core Coin library.
The framework for employing the SIM Voleon library is the same as for ordinary Coin applications: SIM Voleon provides a set of new scene graph nodes to supplement Coin with the new capabilities of volume rendering.
This makes it a straight-forward task to add basic volume rendering to your application, and the data can easily be manipulated through existing interaction features, like manipulators, viewers and widgets.

- 3D texture support using viewport-aligned slicing
- 2D texture support using object-aligned slicing
- Volume data is separated into optimal subcubes enabling large datasets
- Dynamic color lookup tables for voxel colors
- Maximum intensity projection through hardware acceleration
Licensing
SIM Voleon is licensed separately from Coin3D. SIM Voleon is released under a dual licensing model and is available in two editions. Both editions give you full functionality on all supported platforms. Full access to the source code and all available binary packages is provided. More information about SIM Voleon licensing can be found on the SIM Voleon licensing overview.
Installation instructions
SIM Voleon's only dependency is that the Coin library must already have been installed. Installation of the SIM Voleon library from source code is done in the same manner as for other Coin3D libraries, please see this how-to for building instructions.
