VolumeViz

The High-performance Volume Data Visualization Toolkit

VolumeViz enables rich interactive visualization of complex volume data sets. Volume rendering, slicing, iso-surface display, and embedded 3D geometry can be combined in a single Open Inventor®-based application.

Very large data sets that cannot be loaded in memory can even be visualized interactively by using the VolumeViz LDM (Large Data Management) option.

State-of-the-art volume rendering
  • Direct volume rendering using 2D or 3D textures
  • Fast rendering of volume «skin» for opaque subvolumes
  • Faux shading, Edge coloring
  • High-quality rendering, lighting and isosurfaces accelerated by GPU
  • Mapping of volume data onto arbitrary geometry
Multi-data support
  • Mixed volume and polygon data
  • Volume rendering, slicing, iso-surface display, and embedded 3D geometry
  • Multiple-dataset support (multi-channel rendering)


Data-transforming and data-combining
  • VolumeViz supports multiple data sets with data-transforming and data-combining techniques, as well as render combining for even faster and higher quality visualization.



Support of out-of-core volume data (using VolumeViz LDM)

VolumeViz LDM (for Large Data Management) enables access to out-of-core data with optimized multi-resolution management.

VolumeViz LDM also provides a rich data access API that allows applications to take advantage of the LDM technology for accessing data associated with a sub-volume, plane, point or poly-line at arbitrary resolution.
This makes VolumeViz LDM not just a visualization toolkit but also a powerful middleware for volume data management.

  • Very powerful and flexible memory management (LDM)
  • High-level object-oriented data access API
  • Very large volumes, fast data loading and interactive even on low-end machines

On-demand performance

Based on an innovative scalable architecture, VolumeViz LDM* allows slices, probes, camera, etc, to be moved interactively at any time, even on low-end machines.

  • Any portion of the volume, up to full volume, can be displayed immediately
  • Interactive navigation with very large data sets (using VolumeViz LDM)
  • Tested on data sets exceeding several hundreds gigabytes
  • Performance and image quality improve with faster hardware

*VolumeViz LDM is a superset of the VolumeViz extension, available through a separate commercial license, which provides all features of VolumeViz plus the LDM technology.

Manages multi-resolution data efficiently
  • Automatic refinement of displayed image
  • Maximizes image quality for the current view using available resources
  • Loads higher quality with no performance drop
Beyond large data visualization

VolumeViz also provides a rich data access API that allows applications to take advantage of the Large Data Management technology for accessing data associated with a sub-volume, plane, point or poly-line at arbitrary resolution. This makes VolumeViz not just a visualization toolkit but also a powerful middleware for volume data management.

3D visualization and GPU computing

Beyond volume visualization, VolumeViz allows software developers to integrate high- performance computing code through the Open Inventor toolkit. The data access API facilitates the interoperability of VolumeViz with NVIDIA’s CUDA language and provides application developers with a unique, integrated solution for combined visualization and computation with very large 3D data.
