TGLScaleManip
Scale manipulator - attaches to physical shape and draws local axes
widgets with box heads. User can mouse over (turns yellow) and L
click/drag to scale along this axis.
Widgets use standard 3D package axes colours: X red, Y green, Z blue.
TGLScaleManip()
Construct scale manipulator not bound to any physical shape.
void Draw(const TGLCamera & camera)
Draw scale manipulator - tubes with box heads, in local axes of
attached shape, in red(X), green(Y) and blue(Z), with white center sphere.
If selected widget (mouse over) this is drawn in active colour (yellow).
Bool_t HandleMotion(const Event_t & event, const TGLCamera & camera, const TGLBoundingBox & sceneBox)
Handle mouse motion over manipulator - if active (selected widget) scale
physical along selected widget (axis) of the manipulator, so it tracks mouse
action. Returns kTRUE if redraw required kFALSE otherwise.
void LimitScale(Double_t & factor)
Clamp scale to sizable values: 1000 - 1/1000
Guards against div by zero problems.
