36 | |
37 | //! Interactive object class to manipulate local transformation of another interactive |
38 | //! object or a group of objects via mouse. |
39 | //! It manages three types of manipulations in 3D space: |
40 | //! - translation through axis |
41 | //! - scaling within axis |
42 | //! - rotation around axis |
43 | //! To enable one of this modes, selection mode (from 1 to 3) is to be activated. |
44 | //! There are three orthogonal transformation axes defined by position property of |
45 | //! the manipulator. Particular transformation mode can be disabled for each |
46 | //! of the axes or all of them. Furthermore each of the axes can be hidden or |
47 | //! made visible. |
48 | //! The following steps demonstrate how to attach, configure and use manipulator |
49 | //! for an interactive object: |
50 | //! Step 1. Create manipulator object and adjust it appearance: |
51 | //! @code |
52 | //! Handle(AIS_Manipulator) aManipulator = new AIS_Manipulator(); |
53 | //! aManipulator->SetPart (0, AIS_Manipulator::Scaling, Standard_False); |
54 | //! aManipulator->SetPart (1, AIS_Manipulator::Rotation, Standard_False); |
55 | //! // Attach manipulator to already displayed object and manage manipulation modes |
56 | //! aManipulator->AttachToObject (anAISObject); |
57 | //! aManipulator->EnableMode (AIS_Manipulator::Translation); |
58 | //! aManipulator->EnableMode (AIS_Manipulator::Rotation); |
59 | //! aManipulator->EnableMode (AIS_Manipulator::Scaling); |
60 | //! @endcode |
61 | //! Note that you can enable only one manipulation mode but have all visual parts displayed. |
62 | //! This code allows you to view manipulator and select its manipulation parts. |
63 | //! Note that manipulator activates mode on part selection. |
64 | //! If this mode is activated, no selection will be performed for manipulator. |
65 | //! It can be activated with highlighting. To enable this: |
66 | //! @code |
67 | //! aManipulator->SetModeActivationOnDetection (Standard_True); |
68 | //! @endcode |
69 | //! Step 2. To perform transformation of object use next code in your event processing chain: |
70 | //! @code |
71 | //! // catch mouse button down event |
72 | //! if (aManipulator->HasActiveMode()) |
73 | //! { |
74 | //! aManipulator->StartTransform (anXPix, anYPix, aV3dView); |
75 | //! } |
76 | //! ... |
77 | //! // or track mouse move event |
78 | //! if (aManipulator->HasActiveMode()) |
79 | //! { |
80 | //! aManipulator->Transform (anXPix, anYPix, aV3dView); |
81 | //! aV3dView->Redraw(); |
82 | //! } |
83 | //! ... |
84 | //! // or catch mouse button up event (apply) or escape event (cancel) |
85 | //! aManipulator->StopTransform(/*Standard_Boolean toApply*/); |
86 | //! @endcode |
87 | //! Step 3. To deactivate current manipulation mode use: |
88 | //! @code aManipulator->DeactivateCurrentMode(); |
89 | //! @endcode |
90 | //! Step 4. To detach manipulator from object use: |
91 | //! @code |
92 | //! aManipulator->Detach(); |
93 | //! @endcode |
94 | //! The last method erases manipulator object. |
95 | //! @warning |
96 | //! On construction an instance of AIS_Manipulator object is bound to Graphic3d_ZLayerId_Topmost layer, |
97 | //! so make sure to call for your AIS_InteractiveContext the method MainSelector()->SetPickClosest (Standard_False) |
98 | //! otherwise you may notice issues with activation of modes. |
