Re: [osg-users] Philips WOW TV displays...
I would just like to take the oportunity to say that autostereoscopic display is a subject as such and realtime autostereoscpic display is a pretty new field of investigation. It is to say that it is quite easy to produce images on an autostereoscopic screen, but much more complex to produce good quality images in terms of depth quality. Having said that, we have developed an autostereoscopic real-time renderer ( but are not using a Philips WOW display (yet?) ) and are now working on specific scene-manipulation algorithms to stick as much as possible to a natural visual accomodation. I guess that this is the key issue. Regards Rémy Kim C Bale a écrit : I too have been playing with these monitors, we have a couple of the 21 touch screen versions. They seem to work very well for viewing models and such, but have a very limited depth range. Has anyone managed to develop a 3D environment that you can walk around, some terrain perhaps or a first person view type sim and achieved good results? I found that the shallow depth range limited it uses in this type of 3D work as objects in the far distance become very blurry. Regards, Kim. From: [EMAIL PROTECTED] on behalf of Krijnen, R.

Hi All, Not sure I've asked this before. If I have, sorry. I've got access to a couple of Philips WOW TV's for a few days, and a colleague has been playing with them for the past week. One of the supporting applications is written in OSG, and generates a split screen image. The left half is the standard 3D view, whilst the right half is the depth map. Now I know that I can set this up myself, however we suspect that there is more to it than this, as we've taken a screen grab of this screen image and sent it to the display, and it still doesn't show it as a combined 3D with depth feel. Does anyone know anything about this display, and perhaps could shed some light on what we need to do to get a normal OSG split screen to work with it? We suspect that there are a few calls that we are missing. Any pointers would be really useful. By the way, using the supplied OSG viewing with our room it looks really quite cool. I was a bit of a sceptic at first, but it seems that Philips may have something really neat here. If you get a chance, check it out.

Re: [osg-users] Stereoscopy, part 2
Hi Renan, Maybe you should have a look at the dual moitor management of your graphic card . If you are running on Windows for instance, you need to extend the desktop instead of using the dual mode screen Rémy ( not fully convinced that this will help anyway ) Renan Mendes a écrit : Hi, It's been a couple of weeks since I first asked about stereoscopy in OSG.

When I finally tried to use the second video monitor (I have a NVIDIA GeForce 6200 dual-head video card), something unexpected happened.

Re: [osg-users] Displaying cables
Just a stupid question : if the bottleneck is the update of the hose, what would you think about using VBOs ? Laurent Di Cesare a écrit : Jean-Sébastien Guay wrote : Hello, For now, we are creating some geometry (quad strips, specifically) to display the cables, and assigning texture coordinates to that geometry, on the fly. (...) I know the cable display needs to be optimized because if I just set the cables' nodemasks to 0, the draw times go from 6.6ms to 2.2ms (for the same view). And there are not *that* many cables... There's a lot of other geometry in the scene which is still drawn in the 2.2ms time... So I would appreciate some pointers. I would have assumed quad strips are pretty fast, so perhaps something else is the problem? There's the fact that the geometry is dynamic, which could mean that OSG is trying to recreate display lists each frame, but I tried setUseDisplayList(false) on the geometry and the cables just did not display anymore... Is there something else I need to do in that case? I have a somewhat similar situation myself. I use capsules to display hoses, which aren't textured but just have a color, and use display lists. Capsules are just cylinders and half spheres, but these are made of a lot of vertices. I ran at something like 1-2 fps(!) when I was redrawing the whole hose everytime the hose changed. When no geometry changed, I shot back to around 25 fps. I got three times faster when I limited myself to changing only the end of the hose, thus keeping the same capsules rather than replacing them with new ones with the same coordinates, color, etc. I then got another factor 3 by making sure I drew as few capsules as I needed. In my case too, the capsules are not that many, I have tens of animated characters moving around, plus a scene to render, but the dynamic shapes ate way more than anything else. I'm not sure if this helps a lot, but I just did this today, and optimizing the geometry was clearly a big win for me. If your app doesn't change all the cables at once, only one part of one cable at a time (a given frame), keeping the geometry should give you a decent boost. If anyone else has other suggestions, I'm interested to hear them too.

Re: [osg-users] Problems with picking and HUDs
Just an idea : AFAIK , If you use a CameraNode under a Transform , the display is then not consistent with the picking : The display of any geometry under the CameraNode will be affected by the Transform, but the IntersectVisitor traversal of the CameraNode will reset the transformation matrix. Put any transform after the cameraNode.
