To add a custom view to the .prc portion of a .pdf document:

1. Create a view object and add it to the file structure and to the product occurrence:

   
             OdPrcViewPtr pNewView = OdPrcView::createObject();
             pNewFileStructure->addObject(pNewView);
             OdPrcName name;
             name.setName(L"NE Isometric");
             pNewView->name() = name;
   
             OdPrcProductOccurrencePtr productOc = pFile->fileStructures().last()->fileStructureTree().productOccurrence().last();
             OdPrcObjectIdArray &arr_view = productOc->annotationViews();
             arr_view.push_back(pNewView->id());
           

   Note that it is important to set the name of the view. The view is available in the .pdf file through its name.

2. Add to the file structure a set of parameters for a scene display and associate this parameter set with the previously created view object:

   
             OdPrcSceneDisplayParametersPtr pSceneDisplayParameters = OdPrcSceneDisplayParameters::createObject();
             pNewFileStructure->addObject(pSceneDisplayParameters);
             pNewView->sceneDisplayParameters() = pSceneDisplayParameters->id();
           

3. Create a camera object, and add it to the file structure:

   
             OdPrcCameraPtr pCamera = OdPrcCamera::createObject();
             pNewFileStructure->addObject(pCamera);
           

4. Set the camera's target, up vector and position. Then associate the camera with the view:

   
             pCamera->lookAt().set(0.0, 0.0, 0.0);
             pCamera->up().set(0.0, 0.0, 1.0);
             pCamera->location().set(5.0, 5.0, 5.0);
             pCamera->setXFov(1.0472);
             pCamera->setYFov(1.0472);
             pSceneDisplayParameters->camera() = pCamera->id();          
           

You can choose the created view in a viewer application by its name:

After selecting the created view, you can see the result:

For additional details, in the examples see the simpleCrossSectioExample() function in the CrossSectionExample.cpp module.
