Detailed Description

Class synchronizing the viewing parameters between multiple renderers.

Two "modes":

Shared camera (default, i.e. sharedCamera = true in constructor), each added renderer gets assigned the same camera (the one from the renderer added first). Pro: Less overhead on updates (only triggering an update on other renderers) Con: The views share the visible area; so if the renderers have different pixel dimensions, viewed objects might be distorted
Synchronized camera settings: An observer is registered to each added renderer, and whenever one of them is updated(=rendered), its main camera parameters (camera position, focal point, view up direction, clipping planes, and parallel scale if source camera has parallel projection turned on) are copied to all other renderers. Pro: Avoids sharing "too much", i.e. avoids distortions and renderers can have separate visible areas Con: Slightly more (coding) effort to synchronize relevant viewing parameters (and potentially error prone - relevant parameters for specific viewing modes might be missed)

Constructor & Destructor Documentation

iARendererViewSync::iARendererViewSync ( bool sharedCamera = true )

Creates a new renderer view synchronization service.

Parameters

sharedCamera whether to use shared camera (true) or just synchronize required view parameters (false). see class description for details.

iARendererViewSync::~iARendererViewSync ( )

destructor, disconnects from all renderers

void iARendererViewSync::addToBundle ( vtkRenderer * renderer )

Adds given renderer to the bundle of renderers with synced views.

Any change in that renderer's viewing parameters will be synced to all other renderers in the bundle.

Parameters

renderer the renderer to add to the bundle

void iARendererViewSync::removeAll ( )

Remove all renderers from the bundle synchronized by this class.

bool iARendererViewSync::removeFromBundle ( vtkRenderer * renderer )

Remove given renderer from bundle.

Stops synchronizing this renderers' viewing parameters with the other renderers in the bundle.
