Re: [osg-users] kd-Tree LineIntersection speedUp
Hi Jean-Sebastien, what i do at the moment is, i walk trought the drawables and collect all triangles, so i don't care about material, ... nor transformations. what i should do is to transform the triangles before insertion. but i don't like this way. another possibility is: for each geometry (hard) we can attache a kd-tree object, and then the intersection visitor transforms the objects when a transformation node is used, this is the way it works with the current intersection visitor (if i am not wrong), so i like just to replace a small part of code in OSG core, to check a ray (line) against the kd-tree and not against the list of triangles in the geometry. so we can speed up the intersection testing. but what we need is to implement this into osg core. /adegli 2007/10/29, Jean-Sébastien Guay [EMAIL PROTECTED]: Hello Adrian, The code as it stands does not currently support transforms. Can you help with that? I have never personally implemented a kd-tree algorithm, so I do not know where this support of transforms needs to be put in. correct, but when we have integrated it into the core of osg, then it should work as expected. I still don't understand why the code would a) not support transformations if it isn't integrated into core OSG b) support them once it is. It's the same code, it won't magically support transforms, you need to write the code for that... Please explain, because there's something I'm missing here.

That second way makes more sense. But you don't necessarily need to integrate it into the core OSG... If you want to do that without having to wait for someone to integrate it into the core OSG, you could just copy the classes you need from the OSG source tree into your sources, rename them so they don't clash and then modify them as needed. That way we could progress on this and later, when Robert is available, you'll have even less changes needed to integrate your code into the core.

[osg-users] NVidia's GLExpert program.
I downloaded the GLExpert program from NVidia's website. It seems to give me output for regular applications that I know are using GL. Anything with OSG (osgviewer cow.osg) doesn't produce output. Has anybody tried this and figured out a way around it? I'm guessing it's due to something grabbing the output handler.

Hi Chris, The OSG does nothing special w.r.t OpenGL setup, perhaps its something related to the windowing setup that GLExport doesn't check for. Could you try examples like the osgviewerGLUT and osgviewerSDL to see if they work OK. Robert.

Re: [osg-users] building osg on release version of leopard
The problem I identified is a fix for building against 10.5 and the build process would have to be smart enough to test it. It would also have to be smart enough to know when it is being built for X11 instead of AGL. I hope Apple fixes the libGL.dylib bug because it has been a thorn in my side for several of the code bases I maintain. Perhaps I didn't understand your solution, I thought your fix required installing a new version of freetype that linked against Apple's open gl instead of the X11 open gl. Dan On Oct 29, 2007, at 3:21 AM, E. Wing wrote: I haven't tried what you suggested so I could be mistaken. But if James's problem is what I think it is, your above suggestion will either not work or could potentially cause other serious/hard-to-identify problems. The problem I',m identifying is a binary interface incompatibility between 10.4 and 10.5. The fix I checked in (which is actually much shorter than your solution because I just add an $(SDKROOT) variable) makes sure to look in the correct SDK locations for things. I suspect your fix is going to try to always link to the native system framework (10.5 in this case) which will cause a linking failure if you are building against the 10.4u SDK and is generally the wrong thing to do. But again, I could be mis-identifying the problem. I do recall a cycle problem kind of like what James described many months ago in a much older seed, but that problem was supposedly fixed quite awhile ago and I haven't encountered it since. (I put together a 10.5 OSG binary package as a test run against the last seed and I did not encounter any build problems as described.) -Eric On 10/28/07, Daniel Larimer [EMAIL PROTECTED] wrote: There is a much easier work around to this X11 Open GL bug and that is to add the following to the linking command.

Re: [osg-users] OSG .net readerwriterOBJ
Hi Dave, Questions are fine, although it's best to post to the osg-users mailing list so that everyone can benefit. (Also you're likely to get a quicker answer.) It's good to hear that osgDotNet is running with VS 2008; you're the first person I've heard from that's tried it. You should be able to load your Maya models in a very similar way to what you would do in unmanaged code: Osg.Node model = OsgDB.Globals.readNodeFile(file.obj); You can then set the scene of the viewer to the model. All of the magic for the .obj loader happens under the covers in unmanaged code, so you don't need to worry about it. -Mike Hi, sorry if you'd prefer to NOT hear questions from the OSG website. I am new to OSG without much experience bridging managed unmanaged code. I have the .net wrappers working with VS 2008 beta C++, creating a cone in a window. I need to be able to load .obj models I created in Maya. I see the unmanaged code for this plugin in the full OSG source I downloaded, but can't seem to figure out how to access this from my managed project. Thanks for any help, or referrals.
