Hi Ümit, I try to use osg::Switch to insert all the data I have in the files( each file in a separate node with his own transform matrix ), so I can switch the nodes in each frame, but I don't know why it seems that the second and following data I insert accumulates the previous matrix transformation, and I don't want this. I write "it seems" because I cannot be sure about that, my models are doing some strange movements that are not correctly. I also have a sphere attached to the root node after I attach the switch node, and it seems to be also afected by the previous transformation... Althought, that's not my biggest problem, I can just fix it by adding and deleting one by one the nodes to the root node.
My problem is that the transformation I apply in OGL is not the same as in OSG, and I need the same transformation. So the gridOrientation is a Matrix3x3 wich contains the rotation in the object. , that's why I'm adding some more values. My matrix rotation in OGL is like that: gridOrientation.set(0,0,rotation.get(0,0)); gridOrientation.set(0,1,rotation.get(1,0)); gridOrientation.set(0,2,rotation.get(2,0)); gridOrientation.set(0,3,0.0f); gridOrientation.set(1,0,rotation.get(0,1)); gridOrientation.set(1,1,rotation.get(1,1)); gridOrientation.set(1,2,rotation.get(2,1)); gridOrientation.set(1,3,0.0f); gridOrientation.set(2,0,rotation.get(0,2)); gridOrientation.set(2,1,rotation.get(1,2)); gridOrientation.set(2,2,rotation.get(2,2)); gridOrientation.set(2,3,0.0f); gridOrientation.set(3,0,0.0f); gridOrientation.set(3,1,0.0f); gridOrientation.set(3,2,0.0f); gridOrientation.set(3,3,1.0f); As I can understand about the precedence of OGL and OSG, if I do translate and then rotate in ogl, I have to do rotate * translate in OSG.... Otherwise, I've tried both combinations, and no one is working... :S Cheers, Pau. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=15115#15115 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
