VolumePro
VolumePro is TeraRecon's own patented hardware rendering solution that
offers real-time 3D volume rendering with unsurpassed image quality
for integration into medical, seismic, scientific, and other high-performance
imaging systems. VolumePro hardware rendering boards are offered in
different configurations to meet a wide range of needs for various imaging
applications. Customers can choose from different board configurations
with one or more ASICs per card, different on-board memory sizes, different
power options, and different physical form factors that best match individual
application requirements. No matter the configuration chosen, VolumePro
delivers both unsurpassed image quality and real-time volumetric rendering
performance for the most demanding data requirements without compromise.
TeraRecon also provides a software development environment toolkit (SDK)
that allows users to easily integrate VolumePro hardware boards into
computer systems that run Windows, Linux, or Sun O/S.
Real-time or interactive volume-rendering has become an invaluable
visualization technique for a wide variety of applications. Volume-rendering
deals with sampled data in three or more dimensions - data such as
CT or MRI scans, seismic data depicting the subterranean structure
of the earth, or atmospheric data describing weather patterns. Typically
datasets depicting physical objects or phenomena are enormous, comprising
data values at points throughout three dimensional space. Volume-rendering
is a way to present such data in visually meaningful ways, showing
what the object or phenomenon looks like, especially in terms of its
interior structure. Real-time volume-rendering does this fast enough
for the user to interactively manipulate the images. The user can
rotate the image, look through it by dissolving away opaque material,
take advantage of motion cues and lighting, etc.
In direct volume-rendering, the entire body of 3D data is processed
each time an image is drawn or displayed. Imaginary "rays" are cast
through the data, picking up color and opacity as they traverse it.
They are then projected onto a computer screen or display surface.
To make the image move or to manipulate it interactively, the data
is re-processed in rapid succession, fast enough for interactive frame
rates. 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; and summing up all the color and
opacity values to create the image. Volume-rendering is fundamentally
different from conventional 3D polygon-based graphics. The latter
is primarily concerned with representing surfaces of objects by placing
polygons on wire-frame models. This is satisfactory for games, animations
and synthetic objects, but it cannot depict the interiors of natural
objects or phenomena.
VolumePro NET
It is the ideal streaming 3D-server solution for networked interpretation
workgroups. VolumePro® NET provides an affordable, shared resource
for visualizing and interpreting large seismic data sets. Together
with VolumePro® 1000, it provides a spectrum of options for adding
performance acceleration to interpretation computing. Rather than
investing in additional, expensive 3D interpretation workstations,
VolumePro® NET can provide high performance and functionality
to low power or older workstations or even laptop computers. VolumePro®
NET's patented technology concentrates powerful 3D and 4D processing
capability in a high-performance server equipped with multiple VolumePro®
real-time volume-rendering boards. This enables multiple, simultaneous,
remote users to run high performance applications by providing streaming
screen updates to the clients on the network. Even simple desktop
PCs can be used to review and manipulate images with up to 8GB, since
the requisite memory and processing power are provided by the server,
not the client. Large seismic datasets can be concurrently processed
and distributed to any PC on the network, providing workstation interactivity
to any connected PC at a fraction of the cost of a fully capable workstation.
