Hallo everyone, I have 3 lines (lineA, lineB, lineC) attached to 3 transformGroups, tgA, tgB and tgC. tgA has tgB for child and tgB has tgC for child:
tgA
|
|---tgB
|
|---tgC
Every transformGroup (tg) has its transformation, so tgB's transformation is
up on to tgA's transformation and tgC's transformation is up on to tg'B and
tgA's transformations.
I would like to rotate tgB about its line axis so the angle between lineA
and lineB, while you look through tgB's axis, to be phi radians (as seen in
the diagram)
Every line is along its tg Y axis.
I would like to know what calculations have to be done to achieve this.
Thank you in advance.
