Hi! I have a very busy question with the Transform3D's lookAt() method. I want to create a custom primitive ( an arrow) with the lookAt-method of the Transform3D. I want to set the constructors arguments of the new arrow primitive with Arrow(Vector3d startPoint, Vector3d endPoint). I have tried to construct the Transformgroup's Transform3d object with the lookAt method several times, but my solutions never work completely.
lookAt(Point3d eye, Point3d center, Vector3d up) the eye position is set to the middle point between the start- and end point. the center Vector is the end position of my arrow. the up vector is any normal vector onto the my arrow vector. Finally I invert my Transform3d and this schould be it. But the arrows are not drawn in the correct way. Please help me. mfg, Horst Sueggel =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
