You can assign a StateSet in the code with a material definition which overrides the colour of the model. Or you can import the file in Blender, fine tune the material definition for the object, save it into OBJ format and open it into OSG. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Weird problem with osgText::Text3D
Hi, I have also experienced problems with Text3D. Specifically, problems with character spacing (possibly kerning related?) where letters will end up overlapping for certain strings. I think 2.9.10 exhibits the overlapping behavior. I also updated to the latest trunk revision at the time (which was r12078), that resulted in the overlapping behavior being fixed, but then the overall text spacing quality was decreased. Try the trunk revision and see if it works for you. Also, I was using FreeType 2.3.12 if I recall correctly. My eventual workaround was to revert to 2D text for the time being. - Judson On 3/8/2011 7:22 AM, Johannes Scholz wrote: Hi, today I encountered a problem using osgText::Text3D.

Hi Johannes, There was a bug in osgText/freetype plugin's handling of kerning that caused negative and wrongly scaled kerning offsets, this produced exactly the problem you described.

Re: [osg-users] Retrieved Vertices for FLT Model Not Consistent
Hi Paul, What you're saying doesn't really make sense. You say you're loading the same model but getting different vertices each time you load it. What makes you think the vertices are different? Does the model render differently and appear visually different for each invocation of osgviewer? No, I think what he's saying is that he gets the same vertices, but not in the same order, each run. I don't have any insight into this, but I would suggest making an algorithm that doesn't depend on the order of the vertices. The order doesn't matter for rendering (apart from the relationship between vertices required by the primitives) so optimizers may well reorder them at any time, and you wouldn't want your algorithm to break because of that...

Re: [osg-users] osgAnimation : correct approach to detect when a skeletal animation has completed ?
Hi, Thank you very much for your replies ! Following your suggestion Cedric, I am now using a TimelineAnimationManager instance instead of the BasicAnimationManager as the update callback. I also took a close look to osganimationtimeline example (thank you for the pointer). Animation stopping in the middle of an iteration. Following the example, I am using ActionStripAnimation instances to hold my animations. Then I am trying to trigger a callback when an ActionStripAnimation with a limited number of iterations x (setLoop(x)) is completed. I got the feeling that a way to achieve it could be similar to the one presented in the example : Timeline.setCallback(ActionStripAnimation.getNumFrames()-1, new Callback); My first problem here is that, when using a realistic number of iterations (like 10), the animation is stopping in the middle (I mean, the last iteration of the animation does not return to the initial state). With the debugger I figured out that the number of frames calculated when calling setLoop(int) was inaccurate of a few units. But even setting it to a closer value does not solve this problem. How to detect the completion of the current animation iteration ? I did not evoke in my first post another requirement of our automaton I am trying to fulfill (my bad :) ). In some cases, the animated object will be looping infinitely on an animation, to be interrupted only when a given trigger is activated. In this case, the application would need to be able to detect when an animation iteration is completed on an infinitely looping ActionStripAnimation (ActionStripAnimation.setLoop(0)). Here the getNumFrames() approach does not seem to be applicable anyway, and the only directions that came to my mind would be : *Adding a nested NodeCallback to the AnimationManager, that would be called at each update traversal and -when the application wants to stop the current looping animation- it would compute the current iteration number of the animation I, and deduce the time by which this iteration will complete (I mean, stopping as soon as ReferenceTime = AnimationStartTime + I*AnimationDuration). That does not sound really elegant to me, but I was able to obtain a working prototype... *Implementing a derived AnimationManager to override the update() method, and make possible to register a callback that will be triggered as soon as the current animation iteration is completed. Sounds better to me, but it is a bit of overkill if I am just missing an simplest way to achieve that. Thank you for reading !

[osg-users] Missing textures with osgexport
Hello all. Today, I downloaded Cedric Pinson's osgexport script (and I've pulled the latest version from the mercurial repo). I made a simple scene, consisting only a plane. I UV-mapped the plane, and exported it to a .osg file. Then loaded this into osgviewer, and the plane was there, but with no texture at all. I took a look inside the file, and noticed that it contains no reference to the texture at all. When I export both the plane and the default lamp, there are some material descriptions in the osg file, but only for the lighting, not for the texture. What should I do to make it work? By the way, I'm using Blender 2.49b, with Python 2.6.2.
