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 frameworkfor further display. This abstract framework is inherited in Application Interactive Services (AIS), notably in:

| Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. aPresentableObject has the display mode aMode; this has the default value of 0, that is, the wireframe display mode. More...
|
|
virtual void | Compute (const Handle< Prs3d_Projector > &aProjector, const Handle< Prs3d_Presentation > &aPresentation) |
| Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. Each of the views in the viewer and every modification such as rotation, for example, entails recalculation. It must be redefined to implement hidden line removal for the object. The user never calls this method himself. This is done via the InteractiveContext object and is dependent on the point of view from which the object is displayed. More...
|
|
virtual void | Compute (const Handle< Prs3d_Projector > &aProjector, const Handle< Geom_Transformation > &aTrsf, const Handle< Prs3d_Presentation > &aPresentation) |
| Calculates the 3D view aPresentation and its updates. The latter are managed by aPresentationManager. A point of view is provided by the projector aProjector, and the geometric transformation which has transformed associated presentable objects is specified by aTrsf. This function is to be used in case where a hidden line removal display cannot be calculated automatically. This occurs when associated presentable objects have been transformed geometrically, but not translated. Warning The transformation aTrsf must be applied to the object before computation. More...

| recomputes all presentations of the object. More...
|
|
void | Update (const Standard_Integer aMode, const Standard_Boolean ClearOther) |

|
virtual void | UpdateClipping () |
| General virtual method for internal update of presentation state when some modifications on list of clip planes occurs. Base implementation propagate clip planes to every presentation. More...
