[osg-users] problem with shader loader

2012-11-27 Thread Peterakos
Hello. Inside OpenSceneGraph-Data i have create a folder with name "mydata". Even though the line: ref_ptr node = osgDB::readNodeFile("mydata/model.dae"); loads the model, i cannot load shader files from the same directory. The call shader->loadShaderSourceFromFile(fileName) fails. The same happe

[osg-users] Non-typical Stereo Usage

2012-11-27 Thread Randall Hand
I need to write an application to use Stereo support (120hz, quad buffered 60hz) to render stuff out to a display, but it's not your typical left-right stereo. In addition, I have a regular viewer showing typical 3D stuff at 60hz (regular double-buffer). In fact, the two views are completely unre

Hi Mike, may I ask what the alternatives are (for remote rendering)? I'm interested in this topic too. Regards, Mathias On 11/27/2012 04:10 PM, Mike Krus wrote: > Hi > > consensus seems to be that RDP is not an option for modern 3D graphics > anyway. There's a few alternatives around though, s

OpenGL 4.x also has extensions which permit an A-buffer implementation: http://blog.icare3d.org/2010/07/opengl-40-abuffer-v20-linked-lists-of.html I've tested this example (and fixed some of the source), but I have not tried to implement it in OSG. The technique does work, and works well, if rock

Hi consensus seems to be that RDP is not an option for modern 3D graphics anyway. There's a few alternatives around though, so I don't think we'll be implementing anything specific on our side. Just a matter of providing recommended solutions for our customers Thanks, Mike On 27 Nov 2012, at

Hi Mike, I don't have any experience with using Mesa under Windows so can't help with this. A more general suggestion I have is that perhaps rendering the image on the remote system and then returning this image to the client would be the more robust way to handle this type of usage rather than r

There's definitely sample code for depth peeling available (osgdepthpeeling) Sorting of geodes by distance is also implemented as a render bin feature - but sorting at geode level may be a bit too coarse. Transparency has been an issue in many forum/mailing list topics - because it's hard and non

Hi we've been having issues with running our application with OSG via Remote Desktop on Windows, resulting in crashes in Microsoft Software OpenGL driver when encountering "large" meshes (as in more than a couple thousand triangles). Messages on this list suggest using Mesa3D. Compiling from s

[osg-users] how about high quality transparency in OSG?

2012-11-27 Thread Gianluca Natale
Hi all. I took a (very quick) look at OSG 3.0.1 APIs, to see if there is some technique for high quality transparency implemented, but I couldn't find anything. So, is there anything already implemented for such stuff? I mean, something like the order independent depth peeling, or the more expens
