[osg-users] ReplicantBody: body velocity problems
Hi all! Sorry again for use this list for ReplicantBody questions... I integrated ReplicantBody with my path planner algorithm but I still have a question. In class KeyboardEventHandler, when load walk animation, the speed wich the body will walk is defined by action-setPropertyFloat( speed, vel );. If I change the vel value, nothing happens. The only way that I could change the velocity was getting the animation and chance the velocity: rbody::Animation* animationWalk = ((rbody::Animation*) m_body_vector[m_curr_body]-getBody()-getCoreBody()-getAnimation(run)); animationWalk-setSpeed(0.3f); It works only if I stop the walk or run animation, set the new velocity, and load walk or run animation again. So, it is not a solution. :-) I need to change the body velocity all the time, without stop the animation. What should I do? Or, what is the better way to do it? Any thoughts would be greatly appreciated. Thank you in advance.

Re: [osg-users] ReplicantBody: body velocity problems
Thank you!! Now everything works! :-) I'm not using the latest svn version, but soon I will change to it, and face the same problems =). Thank you! Renato 2007/8/1, Daniel Sjolie [EMAIL PROTECTED]: Sorry, I was unclear... xAnimationSpeed is not a valid keyword so it is the same as commenting it out... Remove the initial x... If you're using the latest svn version you probably have additional problems... I tried to convert it to osgViewer (from osgProducer) before my vacation but it seems I was not entirely successfull... I've looked closer at the problems now and for the time being you have to run it in single threaded mode with osgViewer... Otherwise you get trouble with bodies thinging they are out of FOV when they are not... Also, the handling of modkeys seems to be broken/missing in osgViewer... /Daniel ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] osgCal + osgViewer::CompositeViewer
I'm trying to use osgCal with osg::CompositeViewer. I did exactly what was showed in the osgCompositeViewer example. When I use osg::Viewer all works OK! With osg::CompositeViewer, everything loads OK, but the characters animations stops. Is there anybody with the same probem? Ah! I also got this same behaviour in some pcs, when I run the osgCalViewer example using: osgUtil::Optimizer optimzer; optimzer.optimize(...); Maybe I'm doing wrong...

[osg-users] Controlling animations in FBX models
Hi, In my application I’m using osg with FBX plug-in. The FBX model that I’m using has a unique sequence of animations, called “Take 001”. The sequence includes a walk, stand, and run animations. Is there a way to specify that from frame 0 to 100 I have the walk animation, from frame 1001 to 3000 I have the stand animation, and so on? I’m using the AnimationTimelineHandler, as in the example, but I could not figure out how to do it. I play the entire sequence of animations, but I cannot separate them. -- Renato Silveira (Ph. D.

I need to do something similar at the moment. I know MotionBuilde can export fbx with multiple takes, but 3ds max can not. I plan to write a node visitor that will find and split any osg animations into multiple takes. Perhaps using a config file. Shouldn't take long, I'll send you a copy when I'm done. If you export your fbx from osg as a .osg file you can see how the data is stored and looks petty straight forward to split it. Alternatively you can use MotionBuilder and I know the FBX plugin is capable of loading the multiple takes.

[osg-users] osgAnimation::Action.cpp - Bug?
I compile the osg library with the svn last version and I got a dynamic
error after load my FBX file. Integer division by zero.
I debugged and found that the error was in the first line of the function:
bool osgAnimation::Action::evaluateFrame(unsigned int frame, unsigned int
resultframe, unsigned int nbloop )
{
*nbloop = frame / getNumFrames();*
resultframe = frame;
Perhaps my FBX model lacks some information. Just to test, I write the
following condition after that line:
_numberFrame = (getNumFrames() == 0)? 25 : getNumFrames();
nbloop = frame / getNumFrames();
and everything works. I don't know if it is a bug or a problem with my
model, but it fixed the problem.
Any suggestions for a more appropriate fix?
Renato
