Translation manipulator - attaches to physical shape and draws local axes widgets with arrow heads.

User can mouse over (turns yellow) and L click/drag to translate along this axis. Widgets use standard 3D package axes colours: X red, Y green, Z blue.

Member Function Documentation

◆ Draw()

void TGLTransManip::Draw ( const TGLCamera & camera ) const

virtual

Draw translation manipulator - tubes with arrow 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).

Implements TGLManip.

Definition at line 55 of file TGLTransManip.cxx.

◆ HandleMotion()

Bool_t TGLTransManip::HandleMotion	(	const Event_t &	event,
		const TGLCamera &	camera
	)

virtual

Handle mouse motion over manipulator - if active (selected widget) translate physical along selected widget (axis) of the manipulator, so it tracks mouse action.

Returns kTRUE if redraw required kFALSE otherwise.

Reimplemented from TGLManip.
