Hi All, I have an simple math question which I had resolved before but now I can't figure out what would be the problem. I have car model which's direction is x coordinate. I want to translate it by using it's current direction. So I need to know it's next visit coordinate while it is rotating to left or right. So this is my math;
carMatrixTransform->get(quad); osg::Vec3d carDirection = quad * osg::Vec3d(1.0, 0.0, 0.0); // getting car's x direction vector. Then using carDirection, I calculate each next related coordinates respectively by using iterator. osg::Vec3d DestinationPos, SourcePos; DestinationPos = SourcePos + carDirection * iterator; (iterator >= 0) Do you think it is wrong? Best Regards. -- Ümit Uzun
