Detailed Description

Interactive object class to manipulate local transformation of another interactive object or a group of objects via mouse. It manages three types of manipulations in 3D space:

translation through axis
scaling within axis
rotation around axis To enable one of this modes, selection mode (from 1 to 3) is to be activated. There are three orthogonal transformation axes defined by position property of the manipulator. Particular transformation mode can be disabled for each of the axes or all of them. Furthermore each of the axes can be hidden or made visible. The following steps demonstrate how to attach, configure and use manipulator for an interactive object: Step 1. Create manipulator object and adjust it appearance:
Handle(AIS_Manipulator) aManipulator = new AIS_Manipulator();

aManipulator->SetPart (0, AIS_Manipulator::Scaling, Standard_False);

aManipulator->SetPart (1, AIS_Manipulator::Rotation, Standard_False);

// Attach manipulator to already displayed object and manage manipulation modes

aManipulator->AttachToObject (anAISObject);

aManipulator->EnableMode (AIS_Manipulator::Translation);

aManipulator->EnableMode (AIS_Manipulator::Rotation);

aManipulator->EnableMode (AIS_Manipulator::Scaling);

Definition: AIS_Manipulator.hxx:94

AIS_Manipulator::AIS_Manipulator
AIS_Manipulator()
Constructs a manipulator object with default placement and all parts to be displayed.

Note that you can enable only one manipulation mode but have all visual parts displayed. This code allows you to view manipulator and select its manipulation parts. Note that manipulator activates mode on part selection. If this mode is activated, no selection will be performed for manipulator. It can be activated with highlighting. To enable this:
aManipulator->SetModeActivationOnDetection (Standard_True);

Standard_True
#define Standard_True
Definition: Standard_TypeDef.hxx:57

Step 2. To perform transformation of object use next code in your event processing chain:
// catch mouse button down event

if (aManipulator->HasActiveMode())

{

aManipulator->StartTransform (anXPix, anYPix, aV3dView);

}

...

// or track mouse move event

if (aManipulator->HasActiveMode())

{

aManipulator->Transform (anXPix, anYPix, aV3dView);

aV3dView->Redraw();

}

...

// or catch mouse button up event (apply) or escape event (cancel)

aManipulator->StopTransform(/*Standard_Boolean toApply*/);

Step 3. To deactivate current manipulation mode use:
aManipulator->DeactivateCurrentMode();

Step 4. To detach manipulator from object use:
aManipulator->Detach();

The last method erases manipulator object.
