Detailed Description
Computes the transformation of a ReferenceFrame wrt an ancestor.
This class computes the transformation of a ReferenceFrame with respect to any of its ancestor frames. To use, just specify the root frame and the target frame then call the getLocalToWorld() or getWorldToLocal() method. The accumulated transform between root & target frames is returned.

◆ getLocalToWorld()
| osg::Matrixd& OpenFrames::TransformAccumulator::getLocalToWorld | ( | ) |
Get the transform from origin to its root frame
◆ getOrigin()
| ReferenceFrame* OpenFrames::TransformAccumulator::getOrigin | ( | ) |
Get/Set the origin frame
◆ getRoot()
