Hi there, This might be a load of rubbish and not possible mathematically, but I'm trying to decompose a matrix and apply it to an osg::PositionAttitudeTransform in order to set the PAT by matrix.
The reasoning behind this is I am using PAT to give a human friendly position, rotation, scale for objects in a CAD-style application, but in certain circumstances, I would like to apply a matrix directly to the PAT and say "That's your matrix, use that". I have tried this Code: osg::Vec3 position = matrix.getTrans(); osg::Vec3 scale = matrix.getScale(); osg::Quat rotation = matrix.getRotate(); this->positionAttitude->setPosition(position); this->positionAttitude->setScale(scale); this->positionAttitude->setAttitude(rotation); and it gives odd results. Also I was looking at matrix.decompose but I'm not sure what to do with "Scale Orientation". can anyone put me out of my matrix misery!? Thank you!
