The proper fix is standardise all the platform paths to use the same system, right now the OSX side has kept the old way because of the old Xcode projects not being in sync with Cmake support. Wr.t.t Config + old Xcode projects, this problem occurred to me yesterday just as I was heading offline i.e. SVN comes without the Config files as CMake is the tool that generates them, as potential each platform will have its own Config (especially in the case of OpenThreads) then shipping a standard Config would be inappropriate. Perhaps one could have a Config headers local to the XCode projects to get round this, but it'd be awkward. In the end the right solution is to just get the CMake build working for all platforms, and finally to drop the old XCode projects. Robert.

Re: [osg-users] help on picking and draggers?
Hi, as a general rule, if you're using ref_ptr correctly, you should never have to call ref(). I've written much OSG code over the years, and have never had a need to call ref() directly. The official guidance is to always use ref_ptr when maintaining a pointer to an object derived from osg::Referenced. I chose those words carefully; if you need to preserve/maintain a reference across function calls, or references among different nodes, then always use a ref_ptr. Occasionally, I will use a regular C++ pointer strictly _inside_ a function when I know that reference will not be maintained beyond the scope of that function lifetime. There is a very good ref_ptr tutorial on the OSG website. -- mew On Thu, Jun 19, 2008 at 12:37 PM, Xinyu Zhang [EMAIL PROTECTED] wrote: Thank you. I got the problem solved. The program crashed everytime I tried to select a dragger. It actually had nothing to do with the dragger itself. Just the CommandManager pointer was somehow unaccessable (deleted?). I manually called the ref() and then it worked fine. I paid a lot to learn the smart pointer. Still don't quite understand when they should be used.

[osg-users] View::computeIntersections Bug with GUIEventAdapter::Y_INCREASING_DOWNWARDS?
Hey for a long time I've seen behavior where, if I attempt to use View::computeIntersections before sending any input to the eventQueue, the Y value seems to be inverted. I.e. attempts to pick at the bottom of the screen return results from the top of the screen. This would happen at startup before any mouse input had been forwarded to the viewer. I tried to figure it out when I was still a newbie and gave up since there are several easy workarounds (programmatically simulate a mouse event, etc.) and I figured I was just doing something wrong. Recently when cleaning up some code I figured I'd give it another try, and I think I may have found the source of the problem. - osgViewer::View::computeIntersections calls osgViewer::View::getCameraContainingPosition - which as a side effect provides transformed local_x, and local_y. - depending on getEventQueue()-getCurrentEventState()-getMouseYOrientation(), Y can be inverted in the transformation - EventQueue's constructor's default arg sets mouseYOrientation to GUIEventAdapter::Y_INCREASING_DOWNWARDS - osgViewer::View creates it's eventQueue with no arguments thus has mouseYOrientation Y_INCREASING_DOWNWARDS - EventQueue sets its GUIEventAdapter _accumulateEventState (getCurrentEventState) mouseYOrientation from the orientation passed to its constructor - thus by default View::computeIntersections will invert y - until in Viewer::eventTraversal(), upon a pointerEvent, eventState-setMouseYOrientation(osgGA::GUIEventAdapter::Y_INCREASING_UPWARDS) is called - (setMouseYOrientation does not seem to be called anywhere else in Osg, so the value cant seem to change otherwise) So it seems that it is a bug considering that the start state is always Y_INCREASING_DOWNWARDS and upon any pointer input, always gets set to Y_INCREASING_UPWARDS without regard to any other parameters or conditions. However I can't completely confirm all of this as my hack fix to prove the analysis failed. To prove to myself that this is the issue I call viewer-getEventQueue()-getCurrentEventState()-setMouseYOrientation( osgGA::GUIEventAdapter::Y_INCREASING_UPWARDS ) which should negate the problem, and it seems that it doesn't. Can anyone: - confirm that they have seen this issue before themselves? - confirm that my analysis is (in)correct ? and/or - tell me if/where I got something wrong ?

[osg-users] positioning a node - XYZ with offset in screen space
I have nodes (models, text, etc.) that are positioned in XYZ coordinates that I wish to offset in screen space. My question is what's the best/fastest way to do this. An example follows. I have a piece of text that acts as a label for a point on a sphere. In this case that sphere is an osg ellipsoid model generated by virtual planet builder. I position the text at a given lat/lon/altitude which I translate to a XYZ world coordinate. However, I wish to offset the text in screen space by X,Y pixels. Imagine you want to label a point of interest on this globe but you want the label itself to be offset (updated every frame) by X pixels in the x-dimension and Y pixels in the y-dimension. I have one osg::MatrixTransform node acting as the parent of each text object. I have about 100 of these labels objects. I need to update the offset of the text every few frames. Doesn't have to be every frame, I can accept lazy updates - but it is something that needs to occur rather frequently. What's the best way to accomplish this? I have something working but it's rather slow with 50 or more objects. I'm using IntersectVisitor in the algorithm which is killing performance. Any suggestions? ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hello, as a general rule, if you're using ref_ptr correctly, you should never have to call ref(). I've written much OSG code over the years, and have never had a need to call ref() directly. I agree with Mike, if calling ref() (apparently) fixed your problem then there is a deeper problem with your code, which you should fix. You don't need to micromanage ref pointers like that. Like Mike, I have used OSG a fair deal over the years (perhaps not for as long, but still a lot) and I've never had to call ref() manually either.

[osg-users] NPOT textures - comments
In the olden days when I'd have a texture that wasn't power of 2 I'd use a POT (power of two) texture, update the parts of the texture that I was interested in and fix-up the texture coordinates accordingly. Nowadays I'm more inclined to use NPOT (non-power of two) or texture rectangles. Problem is every time I try to use NPOT textures I get nailed performance wise. If I use texture rectangles no problem - performance is as you'd expect...it just works. The thing I don't like about texture rectangles primarily are the lack of NDC (non-dimensional coordinates). Maybe I'm old fashioned, but I like my coordinates to be in the range of 0 - 1. Oh, and the lack of mipmaps are rather disappointing as well, but a small price to pay when you really only need a 2049 x 1025 texture. So, what's your experience? Anyone out there sucessfully using NPOT (not texture rectangles) in the OSG? What's your video hardware/OS/driver? I'm using some very good nVidia cards (FX4600) with the latest drivers on Vista - but NPOT performance is terrible. Perhaps I'm doing something boneheaded.
