Hello,
I am trying to disply a 3-axes coordinate systems similar to one appears in 3d modelers.
They are displyed correctly as right handed system. However, when rotting them some how, the system is flipped to left handed, and agin to right handed in arbitrary manner.
The rotation is performed by dragging the mouse over the view pane.
Could you please inform me of what is going on?
The 3-axes-drwing code is compiled in a display list.
