Insert another MatrixTransform between your arrow and the AutoTransform to point it the way you want it. -Paul
_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Renan Mendes Sent: Saturday, April 05, 2008 7:31 PM To: OpenSceneGraph Users Subject: Re: [osg-users] Dark Side of The Moon Hi, Paul. Thanks for the tip about the AutoTransform. I'm not being able though to initialize the object I'm attaching to this node in the expected position... It's a 3D mouse arrow, composed of a cone and a cylinder at the bottom - very simple. When I do the following: this->setPosition(osg::Vec3f(-3/sqrt(2.0)*ALTCONE/4, 0.0, -3/sqrt(2.0)*ALTCONE/4)); this->setRotation(rot); // rot is a certain quaternion the arrow starts in the right position, when the camera is at its home position (looking at the direction of the positive y-axis). But when I add: this->setAutoRotateMode(ROTATE_TO_SCREEN); it's like the two other commands are ignored, and the arrow always appears as being looked from the top. What should I do? Thanks again, Renan M Z Mendes
