Re: [osg-users] Getting animations initial frame bones matrix

I don'n understand how could I get the bone global matrix with target values. In channels for each bone we have translate(osg::Vec3), rotateX(float), rotateY(float),rotateZ(float) and scale(osg::Vec3) How can we get the transformation matrix with all this data? Thank you! Cheers, Aitor -

Re: [osg-users] [vpb] Placing an object on a UTM file generated with osgdem

For the record, it looks like the camera "up" vector when using an osgdem-generated terrain with UTM coordinates should be (0,0,1) as opposed to the (0,1,0) that is often seen. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=46090#46090 __

Re: [osg-users] [vpb] Placing an object on a UTM file generated with osgdem

If you are placing objects on a UTM terrain using UTM coords, then the localToWorld matrix is a simple osg::Matrix::translate(x,y,z). If you're trying to use lat/long coords, you need to reproject then to UTM before creating this matrix. PROJ4 is the library for this, or something with PROJ4 wrappe

Re: [osg-users] [vpb] Placing an object on a UTM file generated with osgdem

So I've been successfully placing objects using the methods in this thread for geocentric terrains, but now I need to start using UTM terrains so I have to rethink some of this object placement code. Before I was able to get my local-to-world matrix by using ellipsoid::computerLocalToWorldTran

Hi, I have taken up the issue ... is very simple: Code: osgAnimation::Channel* channel = channelList[j]; osg::ref_ptr\osgAnimation::Vec3Target> posTarget = dynamic_cast\osgAnimation::Vec3Target*>(channelList[j]->getTarget()); osg::Vec3 pos = posTarget->getValue(); Here is, for who needs it

Re: [osg-users] Light source default position

 HiYou should normalize it unless this is directional light and modelview matrix has no scale 05.03.2012, 19:00, "Peterakos" :Hello.I found this shader line in the book:float intensity = dot(vec3(gl_LightSource[0].position), normal );i was wondering why he doesnt normalize the light source position
