Re: Softimage Panoramic OpenGL viewer (does it exist?)

[Ben Rogall]

Yes. You should be able to transform to whichever format you want. 
Stereo is also doable. Feel free to contact me if you would like some 
help with an opengl plugin.

Re: Softimage Panoramic OpenGL viewer (does it exist?)

[peter_b]

sounds right to me, and as far as rendering goes, that’s how I would approach 
it.
camera rig with 4 to 6 cameras, (1:1 square, 90 degree fov, aligned to xyz 
axis), the renders mapped to the corresponding sides of a cube for preview, as 
well as for a second stage render with the panoramic lens shader.
You can probably do the second stage with a lat/long distortion effect in comp.

in theory you could do a rendermap through a properly mapped sphere, a UV 
mapped then subdivided cube or indeed just use the panoramic shader to get the 
result in one go - but all of these will give you much slower renders, 
renderartefacts and problems with view dependent effects – so the multi camera 
rig is the way to go IMO.
havent tested it, but if you boolean the subdivided cube into a cylinder you 
could map the square renders on it for direct cylindrical preview of the cubic 
renders.

Doing all of this in realtime in the viewport is way above my head – I’ve found 
camera rig + mapped geo to be sufficient for my previz needs. (some of which 
were quite extensive, needed to be very precise and were for client use as well)

just my 2 cents.

Hi again, never got any reply about this subject and was
wondering if
anyone on the list knows assuming I get someone with some good
coding
experience if its possible to actually write a plugin/viewport
shader or
whatnot in order to enable the possibility of doing panoramic
(up to 360
degree) realtime previews.
Also what would be the actual way of doing this, is it possible
through the
Opengl or Direct3D viewport by using some kind of hack of
writing a buffer
into a quad in camera space (post effect) or by creating an
actual viewport
plugin?
Any documentations/tips on how to sort this?

Maybe Raph, if you are still around in the list could you share
some
thoughts please?

The reason is that we are doing some projects that involves
panoramic
renders and its a pain in the arse/ time consuming process to
use camera
rigs to capture a panorama and then stitching all this together
in one
seamless video which only gives an approximation to what the
exact result
should be.

Re: Softimage Panoramic OpenGL viewer (does it exist?)

[Max Crow]

Andrew Hazelden wrote the Dome master lens shader for Mental Ray to use in
Maya, 3DSmax and Softimage. The positive is its free and it even does
stereo 360 in a latlong format too. The negative is its obviously not
"viewport" real time, but at least it doesn't require tedious stitching!

http://www.andrewhazelden.com/blog/2012/06/domemaster3d-lens-shader-for-softimage/

However, he recently released a panoramic VR playblast for Maya at $249, so
maybe persuaded to do a softimage version if you have the funds.

You can write a shader for use in the realtime viewport, or custom display 
host.  Between the two graphics library choices, I would go with OpenGL 
because DirectX inside of Softimage is quite flakey/buggy and only supports 
DirectX 9, possibly 10.

Softimage Panoramic OpenGL viewer (does it exist?)

[Nuno Conceicao]

Hi Softimagers
We just started a project that needs to be rendered with a panoramic 270
degree stereoscopic view.
We already sorted out the panoramic camera stereo lens shader problem, but
the issue is the softimage viewport.

I was wondering if some other studio already had such kind of projects and
came up with a solution for the panoramic view (can be cilindrical for ex)
even if its not a stereo solution, but if at least a proper panoramic
opengl view would be enough for the previz stage.
