Hardware accelerator for volumetric 3D vector field rendering?

NTDEV
1

Sorry, this is not really a driver problem but I saw some folks in this area in
the past that may know. Google turned out some publications, IEEE papers only.
So here it goes.

Is there any not-so-expansive hw accelerator engine out there that can render 3D
vector and scalar fields in realtime? I have huge 3D vector and scalar fields
data coming out off my time domain PDE solver at the time of n*dt of interested.
It’s dog slooooooow to visualize it in matlab or other sw visualization tools.

What I need is for scalar fields, I want to see the slice or contour view, kind
of like MRI. It would be nice if it can show the gradient of the field with
little arrows.

For vector fields it’s trickier. I want to visualize the field, its potential,
curl and divergence based.

Have you taken a look at VolumePro boards?

Inaki, thanks for the plug! I wrote the drivers for the VolumePro. They’re
my current babies. :slight_smile:

The Vp1000 and Vp2000 boards are not 3D accelerators. They are Volume
Renderers. You can Google for “Volume Rendering” and try for example the
Stanford University site to understand the difference. These boards have
one, two or four processors, and they are also tightly coupled with the VLI
library, which converts from certain 3D scalar field formats (for example,
DICOM, used in MRI machines) to a stream of low level rendering commands to
the chip.

Our typical volume might have 512 or 1024 slices of 64-bit information, each
slice being a 512x512. I have actually seen 1024x1024x1024 volumes, we can
handle that too. Our rendering speed depends of course on the volume size,
but a 512x512x512 volume shows anywhere between 5 and 10 frames per second,
depending on the complexity of the image. We use Ray Tracing techniques to
render, we hold several patents on that area, and we’ll be at Siggraph
showing it.

You can take a look at http://www.terarecon.com for more details, or, if you
send me an email I can switch you to the right person. You can also call me,
I’m at (978) 369-6500, extension 222.

Alberto.
