Display properties

Properties that can be managed without the knowledge/intervention of the InterfaceGeometry:

  • pointSize (the user preferred value is stored here, the access to the actor needs InterfaceGeometry knowledge)

Properties that need to be managed by the InterfaceGeometry itself (not boolean state managed somewhere by vtk, not integer/float value manage in InteractiveViewer as a user-preference)

  • linesAsTubes (the InterfaceGeometry needs to add/manage a filter before the mapper)

Detailed Description

InteractiveViewer is used to view 3D objects and slices (anything that provides either a InterfaceBitMap or a InterfaceGeometry).

It contains a renderer (class RendererWidget) that combines VTK and QT. The RendererWidget instance manage all the display at the VTK level. InteractiveViewer delegates all pure VTK level stuff to the renderer. All things that needs InterfaceBitMap/InterfaceGeometry interaction/knowledge/access are manage at this level. The keyboard events are all managed in InteractiveViewer as well. Keyboard/Mouse interactions: check "what's this?" on the scene 3D to get all interaction shortcuts.

There are five default InteractiveViewer "singleton" instances named:

InteractiveViewer class is completely independant from MainWindow application skeleton (and please keep it that way!)

InteractiveViewer manages a list of cameras. Each camera has a name. Use getCamera(QString) to create a new camera, or get the default camera and setActiveCamera(QString) to change the active camera. The default camera is called "default".

InteractiveViewer manages picking session. A picking session starts when the control key is pressed and the left mouse button is clicked and ends when the mouse button is released. A picking session is a nice/quick way to do a lot of picking by simply moving the mouse, without the need to click for each picking. At the start of a picking session, the picking action is determined: it is either selection or unselection. If one of the first picked components was already selected, then the user wants to unselect, therefore picking action is "unselection", and all subsequently calls to pickPoint(..) or pickCell(..) will use pickingIsSelecting=false (2nd parameter of the method). If the first picked component was not selected, then the picking session is going to select any picked component.

The following help is for InteractiveViewer/RendererWidget developers, please read if you want/need to change anything in one of this two class. It should help you in your coding decisions (hopefully!).

  1. Keyboard shortcut policy: for keyboard shortcuts do not use the Ctrl key modifier for letters/digit (e.g Alt-P is ok, Ctrl+Arrows is ok, but Ctrl-P is not). Ctrl-Letter/Digit shortcuts should only be used for the application shortcuts.
  2. That's it for now!

Member Enumeration Documentation

describes the current mode of display.

It is usefull to change the way the currently selected Components look compared to the unselected ones. In the default mode a Component is not highlighted, not shaded and not hidden.

Enumerator
OFF 

both selected and non-selected Components are in default mode

SELECTION 

the selected Components are in default mode, the non-selected Components are shaded

SELECTION_ONLY 

the selected Components are in default mode, the non-selected are hidden

Different kind of picking must be available: pixel in slice, a point, a cell, ...

So far, only pixel picking is implemented.

Enumerator
PIXEL_PICKING 

pick a pixel on a Slice

POINT_PICKING 

pick a point in the VTK representation of an Geometry

CELL_PICKING 

pick a cell in the VTK representation of an Geometry

NO_PICKING 

no picking possible
