Thanks. I didn't really think I went into any great deoth on ABSOLUTE versus
RELATIVE, though.

Hello Forum,


OSG Transform allows to specify its reference frame and by default the
reference frame is relative. and the other one is the absolute.
And the two are specified by different code identifier.

We can view transformation in 2 ways.

1. relative to  the fixed coordinate system.
2. Local movable coordinate system.

There is no practical difference and just a matter of viewpoint.

What is the purpose of OSG to specify them separately as follows:

osg::Transform::RELATIVE_RF.

Any example would be of great help!!!



Regards
Sajjad
