Re: [osg-users] Any recent work on CIGI interfaces to OSG?

VT-Mak's VR-Vantage product is OpenSceneGraph-based, and it does in fact support CIGI... They told us we'd have better luck using DIS or HLA (their specialties), and weren't in a position to demo CIGI capabilities to us... It's actually a pretty great product, otherwise, and we told them if they'd

Hi Chris, I work on an OpenSceneGraph-based image generator for the Federal Aviation Administration that is built on the CIGI protocol. Like you, we originally started from MPV and worked from there. Thankfully we threw all that code away and started from scratch. I don't know how much has change

ed. I guess my question still kinda stands, though... Wouldn't it be better to use an explicit std::isnan on line 221 instead of using whatever is in the global namespace? Thanks! -Chris B On Tue, Apr 10, 2012 at 5:25 AM, Alberto Luaces wrote: > Hi Chris, > > Chris Best write

Been having a compile problem trying to build our system on Fedora 16 for a while now. We waited for a couple more releases of OSG to see if it would resolve itself, but it seems it hasn't... In file included from /usr/local/include/osg/Vec2f:17:0, from /usr/local/include/osg/Vec

David, Now that I've had a chance to review the literature, this does seem like a much better approach. Of course, convincing everyone to throw away all the work we've done in the mean-time will be an interesting exercise in diplomacy, but it will be worth it. Thanks for the pointer. -Chris B O

David, Interesting. I'll read some of the papers on this later this week when I have some more time. Based on my cursory glance at the wikipedia entry on 'deferred rendering,' am I understanding correctly that what's primarily done is to use the Z-buffer to cut down on the amount of geometry that

2008-12-05 Thread Chris Best
Hi all, I'm currently working on extensions to our existing application to allow us to render several (as in 100+) lights in a single scene and (hopefully) maintain usable framerates. Currently I'm using a cull callback to create multiple RenderStages so that the lights can be additively blended i

[osg-users] GL_NV_depth_clamp

2008-06-25 Thread Chris Best
I'm currently trying to render infinite shadow volumes in OSG using the GL_NV_depth_clamp extension. This extension disables the near and far clipping planes on nVidia graphics cards. I've tried both using setMode() on the stateset associated with my shadow volume geode and calling glEnable() in th

[osg-users] Questions about PixelBufferObject

2008-06-05 Thread Chris Best
Quick question... Based on digging through the source, it seems all PixelBufferObjects are currently automatically set to GL_PIXEL_UNPACK_BUFFER_ARB by default and there's no way to change this to GL_PIXEL_PACK_BUFFER_ARB, correct? Meaning they can only be used for writing to the framebuffer, not r

First time posting to the list, so please bear with me... I'm currently trying to attach a lightsource node to the front end of an aircraft model in the application I'm working on that acts as a spotlight (to simulate landing lights/head lights). Even though I am setting the stateset up how (I thi
