VolumePro 1000
The VolumePro 1000 family of 3D real-time volume rendering hardware
boards are second generation products built on their predecessor,
VolumePro 500. Introduced in Sept 2001, VolumePro 1000 products represents
a significant technological advance in the area of 3D computer graphics.
VolumePro technology provides both real-time 3D performance for large
volume datasets and unsurpassed image quality without compromise.
VolumePro is a scalable rendering solution where multiple chips or
multiple cards can work in parallel in a system to manage larger memory
or processing needs including the ability for distributed rendering.
Embedded geometry allow for either opaque or translucent polygon objects
to be embedded directly within the volume data. VolumePro 1000 is
offered with up to 4GB of volume memory on a single PCI card, allowing
users to load extremely large datasets. VolumePro technology makes
possible real-time performance for volume sizes of 512³. Image
quality is unsurpassed based on TeraRecon's XY image-order algorithm.
Flexible voxel formats allows for powerful image segmentation, image
fusion, and image difference. Support for perspective volume rendering
for fly-through applications and stereo projection is included.
VolumePro technology is the optimum solution for high-performance
visualization applications, including medical imaging, seismic interpretation,
scientific visualization, or cluster computing. Introduced in Sept
2001 and upgraded in 2002 and 2005, VP1000 uses a second generation
ASIC, proceeding VolumePro 500. VolumePro 1000 is the only commercially
available hardware volume rendering solution available, and has been
well accepted by the market for its real-time performance and outstanding
reliability.
VP1000SJ: Single ASIC Hardware Board
VP1000SJ is a half-size PCI card with a single
ASIC on board. Users can choose 512MB, 1GB, or 2GB of on-board volume
memory, depending on the volume size of the application. The VP1000SJ
is powered by the PCI bus. No power cables are required.
VP1000J: Single ASIC Hardware Board
VP1000J is a full size PCI card with a single ASIC and 4GB per board.
VP1000 comes powered in 2 ways: 1) powered by the PCI bus. No power
cables are required; or 2). supplied power cable connected to the
PC power module or an power external supply.
Ease of integration is assured with
TeraRecon's software development toolkit for Windows, Solaris, and
Linux platforms. VolumePro boards are sold to world class manufacturers
in medical, seismic, scientific, research, super-computing, and other
advanced visualization application areas.
• Real-time performance for volumes
up to 512³
• Stores between 256MB and 2Gbyte
of volume memory on a single PCI board
• Ability to embed opaque and translucent
polygon surfaces within the volume data
• 8-, 16-, and 32-bit voxels on
up to four customizable channels
• Full size PCI card uses 64-bit,
66Mhz for faster data downloading
• Concurrent volume updating and
rendering
• Arbitrary super-sampling in all
three dimensions
• Classification and interpolation
in either order
• Introducing x-y image order rendering
for superior image quality
• Up to 8K voxels in any dimension
in one pass
• Support for super-volumes and
multiple board implementations
• Ignores voxels not contributing
to visible sample for improved performance
• Depth and image filtering based
on opacity, gradient direction, and gradient magnitude
• Gradient lighting applied to
every sample point to make samples look like surfaces
Cluster Computing:
PCs have all the computer elements necessary for solving complex problems
and doing visualization formerly reserved for the most expensive workstations.
When they reach their individual resource limits, they can be clustered
to achieve much higher levels of performance and visualization. The
PC becomes a node. 4 to 32 node clusters are becoming quite common
and clusters using hundreds of PCs are not uncommon. For all these
varied applications, VolumePro technology is the ideal solution for
achieving the performance and enhancing the image quality of the visualization
task.
The key processes required to render the 3D volumes into a 2D image
are:
• Casting the rays through the
volume
• Assigning color and opacity values
to the sample points
• Calculating gradients and assigning
lighting to the image
• Summing up all the color and
opacity values to create the image
