[osg-users] Problem applying MatrixTransform to PositionAttitudeTransform

Hi all, I am hitting my head against a brick wall with this one. I am trying to use osgManipulators to edit nodes in my scene. I attach a node to a manipulator, rotate it, and then detach the node from the manipulator and apply the manipulator's MatrixTransform to the node's

Re: [osg-users] Problem applying MatrixTransform to PositionAttitudeTransform

Replying to myself, but I found the solution if anybody else might run into this. Calling getRotate() on the matrix can give unexpected results if there was also a scale transform involved. The correct way is to call Matrix.decompose(..) to get to the contributing parts:

Re: [osg-users] Problem applying MatrixTransform to PositionAttitudeTransform

Hello Morné, Calling getRotate() on the matrix can give unexpected results if there was also a scale transform involved. The correct way is to call Matrix.decompose(..) to get to the contributing parts: I was going to point that out, and it's even in the osg::Matrix header doc comments for

Re: [osg-users] Problem applying MatrixTransform to PositionAttitudeTransform

Hi J-S, Yup, the documentation certainly helped. In this case I blame automatic code completion and bad assumptions. I thought there would be something in osg::Matrix that would return the individual composing parts and autocomplete suggested getRotate() when I typed in 'get'. I just assumed
