[osg-users] ScalarBar vertical

[Tomas Hnilica]

Hello all,

does anyone use the osgSim::ScalarBar with vertical display in HUD?
I would like to show the scalarbar vertically on the left screen side.

In the example osgscalarbar there are two ways of ScalarBar displaying, HUD one
does not show when changed to VERTICAL, the other one does not affect such
setting...

In the HUD there are some 'magic' transformations that probably works only for
horizontal scalarbar...

many thanks in advance,
Tomas

There isn't any magic going on, its the scalar bar is geometry like
any other in the OSG.  To place it in the correct place you either
need to set its initial values appropriately or position it using a
transform.
