stereo3D problem

When i use stereo view in wireframe mode it is all OK, but when i switch to
shaded mode it looks like most of model is hidden for right eye (hidden by a
sort of white rectangle)(for left it is ok).
Besides, during rotate SW generates image only for one eye.
Is that normal?

 

Maybe a totally dumb question, but what is "stereo" view??? It doesn't ring
any bells with me, and I've been here a while.

Not the notion that it is on 2 or more monitors?

Hmm, what about an add-in which would view the stereo pair in a separate
window? Gonna try to write one.. ;-)

-h-

 

is it possible that shaded mode uses another stereo type or timing?
a while ago I directed you to www.stereo3d.com for info-maybe there is
something at that site to help you?or someone who visits there who can -it
seemed to me that they are a dedicated and technically knowledgeable lot.
I would like to know how you managed wireframe.
I am definitely interested if you get shaded operating.
cheers

 

i ordered my glasses this weekend. should show up in 2 days. i am
writing a solidworks add-in for creating sereo views.

SldWorks::EnableStereoDisplay
ModelView::SetStereoSeparation
ModelView::GetStereoSeparation

i know your site has a lot of info. This is wear i am getting my
glass's from. they ship everywere. and the glass's will work with any
video card that has. Open GL,DirectX,Glide. They say dont even use the
drivers that come with it if you have an nvidia card. nvidia drivers
are better. nvidia is everywere now not only taking over solidworks.

 

great! I've been contemplating using stereo for a while now but I don't have
the programming know how to make it happen.please keep us informed of
progress. : )

 

Note: I`ve triet to set these in VB, and nothing happend.
It works only with a special plug-in ( i`ve managed to get one from John
Williams (thanks) and will resend if anyone want it)
Hope that you will write this kind of special plug-in because stereographics
plug-in i am talking about works only with 98, 98+ and 2001 version, not
with SW2003.

 

there is a device called "stereo3D shutter glasses" and it works as follows:
it screens either right or left eye, while displaying image for the other
eye on the monitor. It requires high refresh rate (>100Hz) because on lower
R.R. you will see flickering (100Hz means there is 50Hz for eye). My tests
indicates that at 120Hz image is quite stable, and on 144Hz there is no
flickering at all.
SW supports this mode only on Quadro series.

 

wireframe: i have downgraded to SW2001, installed Stereographics plug-in ,
SoftQuadro-ed my Ti-4200.
After a bit of tweaking refresh rates it started to work.

 

If this really gets up and running, it would make for an interesting display
at our user group meeting. Especially if it would work with the projector.
But, the projector probably wouldn't be able to handle the high refresh
rate.

Which reminds me, on the news last night they has a story about a guy that
projected the TV onto the side of his neighbor's house so they all could
watch the Chiefs beat up the Raiders last night. Looked like a pretty cool
idea!

people have experimented with this using 2 projectors and overlapping the
images -using a graphics card for dual monitors and with quad buffering.the
audience views with anaglyph glasses-blue/red (or green/red)-these can be
purchased in bulk quite cheaply.
cheers

 

whoops I got that mixed up
2 projectors for blanking l/r type glasses
1 projector for anaglyph viewing

 

I recall experimenting in High School, just taking regular slides from
two viewpoints, and then projecting from two projectors that have
polarizer filters on them. The person viewing also wears special
polarized glasses to separate the two images for each eye. It was
quite effective.

I know this can be done with some video projectors, as long as they
are not LCD type, which are already polarized, but not the way you
need for the effect. DLP and CRT type projectors work OK.

The only need is to generate the two views on two different display
outputs for the projectors. The VBA which was mentioned to create two
stereo views could do this if the views can be placed on two different
displays (perhaps by putting them in their own windows)

The big benefit to this approach (using polarized glasses) is that
the glasses are very cheap. The shutter glasses can be had for around
$50, but still to expensive for many situations with multiple viewers.

However, I am really longing for a reasonably cost system which
provides viewpoint tracking. Some of my large, complex assemblies are
really difficult for the casual viewer to comprehend, even with the
wonderful shading and rotation capabilities. The simple act of
shifting your head for a slightly different vantage point is very
important to get a "feel" for the object. If the display is done on
just a monitor, the results are called "Fish tank Virtual Reality".

This "Fish Tank VR" should be pretty simple to implement, but I've
never seen a low cost version, they all start at around $60,000. Yet,
the hardware to do it (beyond a good video card) should cost under
$100. The motion tracking could be done by a $20 camera which follows
a red LED (or infrared) on a set of LCD shutter glasses.

I'm puzzled why no CAD company has implemented this... even if just
for the "cool" factor to get the marketing buzz.

 

just tagging in here since I cleaned my messages again.....
how does NVIDIA's stereo addin work in with games?
presumably the graphics routines are already to go and just need to detect
and interface appropriately with the application
surely this can it be modified to interface with SW??

 

Games does not need to know that they are displaying stereo.
It`s a driver function to shift a perspective point of wiev a little bit
right or left during rendering phase - it`s fast because you don`t need to
rotate all the objects - they are only projected little right or left
depending on their depth. Of course evrything have to be shaded and
rasterized twice, so overall performance lost is very little below 40%-45%.
this is a function either in driver or DirectX, anyway transparent to the
application, wich can controll only what values are written to Z-Buffer (
and uses it anyway)

 

ok so what's the problem using NVIDIA for stereo? I am sorry I don't
understand why SW isn't available -does it need to be called somehow?

 

I think, that mainly because NV allows stero only in fullscreen DX/OpenGL
modes. SW uses windowed mode.

 

ah yes I see... hmmm...dead end then ...how does the stereographic plug in
manage it then?
