A framework to supply the Graphic3d structure of the object to be presented. On the first display request, this structure is created by calling the appropriate algorithm and retaining this framework for further display. This abstract framework is inherited in Application Interactive Services (AIS), notably by AIS_InteractiveObject. Consequently, 3D presentation should be handled by the relevant daughter classes and their member functions in AIS. This is particularly true in the creation of new interactive objects. More...

Public Member Functions | |
PrsMgr_Presentations & | Presentations () |
Return presentations. More... | |

Get ID of Z layer for main presentation. More... | |
virtual void | SetZLayer (const Graphic3d_ZLayerId theLayerId) |
Set Z layer ID and update all presentations of the presentable object. The layers mechanism allows drawing objects in higher layers in overlay of objects in lower layers. More... | |
Standard_Boolean | IsMutable () const |
Returns true if object has mutable nature (content or location are be changed regularly). Mutable object will be managed in different way than static onces (another optimizations). More... | |
virtual void | SetMutable (const Standard_Boolean theIsMutable) |
Sets if the object has mutable nature (content or location will be changed regularly). This method should be called before object displaying to take effect. More... | |
Standard_Boolean | HasDisplayMode () const |
Returns true if the Interactive Object has display mode setting overriding global setting (within Interactive Context). More... | |
Standard_Integer | DisplayMode () const |
Returns the display mode setting of the Interactive Object. The range of supported display mode indexes should be specified within object definition and filtered by AccepDisplayMode(). More... | |
void | SetDisplayMode (const Standard_Integer theMode) |

void | UnsetDisplayMode () |
Removes display mode settings from the interactive object. More... | |
Standard_Boolean | HasHilightMode () const |
Returns true if the Interactive Object is in highlight mode. More... | |

At least one display mode index should be accepted by this method. Although subclass can leave default implementation, it is highly desired defining exact list of supported modes instead, which is usually an enumeration for one object or objects class sharing similar list of display modes.

Key interface methods to be implemented by every Selectable Object:
Warning! Methods managing standard attributes (SetColor(), SetWidth(), SetMaterial()) have different meaning for objects of different type (or no meaning at all). Sub-classes might override these methods to modify Prs3d_Drawer or class properties providing a convenient short-cut depending on application needs. For more sophisticated configuring, Prs3d_Drawer should be modified directly, while short-cuts might be left unimplemented.

Returns true if the interactive object is infinite; FALSE by default. This flag affects various operations operating on bounding box of graphic presentations of this object. For instance, infinite objects are not taken in account for View FitAll. This does not necessarily means that object is actually infinite, auxiliary objects might be also marked with this flag to achieve desired behavior.

Removes previously added clip plane.
thePlane | [in] the clip plane to be removed from map of clip planes. |

Replace aspects of existing (computed) presentation groups, so that the new aspects can be applied without recomputing presentation. It is NOT recommended approach, because user has to fill such map and then search for each occurrence in computed groups. The recommended approach is computing presentation with necessary customized aspects, and then modify them directly followed by SynchronizeAspects() call.

Set clip planes for graphical clipping for all display mode presentations. The composition of clip planes truncates the rendering space to convex volume. Please be aware that number of supported clip plane is limited. The planes which exceed the limit are ignored. Besides of this, some planes can be already set in view where the object is shown: the number of these planes should be subtracted from limit to predict the maximum possible number of object clipping planes.

Only the interactive object knowns which Drawer attribute is affected by the color, if any (ex: for a wire,it's the wireaspect field of the drawer, but for a vertex, only the point aspect field is affected by the color).

Sets up Transform Persistence defining a special Local Coordinate system where this object should be located. Note that management of Transform Persistence object is more expensive than of the normal one, because it requires its position being recomputed basing on camera position within each draw call / traverse.

void PrsMgr_PresentableObject::SynchronizeAspects | ( | ) |
Synchronize presentation aspects after their modification.
This method should be called after modifying primitive aspect properties (material, texture, shader) so that modifications will take effect on already computed presentation groups (thus avoiding re-displaying the object).
