[LW8]a Hypervoxel speed/Doubler?

Will hypervoxel benefit from the upgrade?
Any speed boost or doubler or any modifications.
Maybe a 3rd party upgrade to it like Max's really nice looking Afterburner.

Hv's rendertime for really nice looking effects are
really astronomical.

yeah i agree!
especially when rendering at HD res, volumetrics arent 4 or 5 times longer but 12-20!
we need a doubler BAD!

Yeah, optimizing and speeding up hypervoxels and particles would be a great help to render times and workflow and production in general.

I asked at the LW user meeting if there were any updates to HV's and I was told NO.

Hopefully in a future release, this will be addressed.

The guy who created and maintained HyperVoxels is with Luxology now, and I'm guessing that Newtek doesn't have a extra expert on volume shading and rendering handy to work on it.

You ppl. should be asking for hardware rendering, not fast volume or voxel rendering (not going to happen anytime soon).

Hehe, well it is not only me actually...
The arrow was pointing towards my avatar which is related to volumetrics in LW, not meant to point to my name as that...
Still, I think that Cims information is a tad outdated maybe?

WHAT?! that skull with muscles is 3D volumertics!?

yes, this is a volume- rendering.

Here is a very, very small preview of the plugin (only temporary site until we find some time to update the page, hopefully soon):

http://www.mediastudio-graz.com/html/volumedic_eng.htm

It is still not entirely finished. We could ship it now, if we wanted to. But we want to add a few final touches first.
We even have a realtime- OpenGL- preview, but it is a bit slow because of the limits of the current SDK...
Actually we have tested 3 different methods for realtime- OpenGL- previews...
Custom- objects the way they are now in LW, do not allow for very sophisticated things though (like trilinear filtering shear warps etc)...
The solution we are using at the moment is a bit different from the usual approach to this, but gives pretty good results.
You will definitely hear and see more about it in the near future...

ooh is it like Visable Human? , so we can slice it?

so how long does it take to render?
and can it do smoke and fire?

Hey!
Well unlike the visible human project you can use CT/MRI/PET/SPECT/3DUS data of any human, or of any living creature (there are even specialy CTs for horses).
You can view the slices too but it is meant to render real 3d- renderings with shading etc.
It is not meant for fire and smoke, but you could do that as well, if you really wanted to.
More solid objects work best though.
Rendertimes depend on the desired quality and a few other factors, but a 640x480- rendering of the head (at this quality- level) to the left takes no more than 30 seconds.
With lower quality we got as low as two seconds for a 320x240 rendering.
The visible human project makes a pretty good base- dataset for this though. I wished I had it for our tests. AFAIK the VHP has 2k res for each slice and a very low slice- distance. For comparison the head to the left had only 256x256 slice- res and a not that optimal slice- distance. However we were still able to achieve pretty good results from this data.

any chance we could somehow take a 3D model and turn it into slices and texture them, etc for cool effects or will this only use high tech data?

We have been thinking about a feature like this actually.
The other way round is already possible
I would like to mention though, that this particular plugin is primarily meant for scientiffic viz and medical viz.
It is NOT meant as a replacement for HyperVoxels.
