vtkViewport provides an abstract specification for Viewports. A Viewport is an object that controls the rendering process for objects. Rendering is the process of converting geometry, a specification for lights, and a camera view into an image. vtkViewport also performs coordinate transformation between world coordinates, view coordinates (the computer graphics rendering coordinate system), and display coordinates (the actual screen coordinates on the display device). Certain advanced rendering features such as two-sided lighting can also be controlled.
|
Add/Remove different types of props to the renderer. These methods are all synonyms to AddProp and RemoveProp. They are here for convenience and backwards compatibility. |
|
Add a prop to the list of props. Prop is the superclass of all actors, volumes, 2D actors, composite props etc. |
|
Convert display coordinates to view coordinates. |
|
Convert display (or screen) coordinates to world coordinates. |
|
Return the center of this viewport in display coordinates. |
|
Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject. Reimplemented in vtkMesaRenderer. |
|
Return the Z value for the last picked Prop. Implemented in vtkMesaRenderer. |
|
Methods used to return the pick (x,y) in local display coordinates (i.e., it's that same as selectionX and selectionY). |
|
Return any props in this viewport. |
|
Get the size and origin of the viewport in display coordinates. Note: if the window has not yet been realized, GetSize() and GetOrigin() return (0,0). |
|
Return the vtkWindow that owns this vtkViewport. Implemented in vtkRenderer. |
|
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject. Reimplemented in vtkMesaRenderer. |
|
Is a given display point in this Viewport's viewport. |
|
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject. Reimplemented in vtkMesaRenderer. |
|
These methods map from one coordinate system to another. They are primarily used by the vtkCoordinate object and are often strung together. These methods return valid information only if the window has been realized (e.g., GetSize() returns something other than (0,0)). |
|
Return the Prop that has the highest z value at the given x, y position in the viewport. Basically, the top most prop that renders the pixel at selectionX, selectionY will be returned. If no Props are there NULL is returned. This method selects from the Viewports Prop list. Implemented in vtkRenderer. |
|
Same as PickProp with two arguments, but selects from the given collection of Props instead of the Renderers props. Make sure the Props in the collection are in this renderer. |
|
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes. Reimplemented from vtkObject. Reimplemented in vtkMesaRenderer. |
|
Remove an actor from the list of actors. |
|
Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h. Reimplemented from vtkObject. Reimplemented in vtkMesaRenderer. |
|
Set the aspect ratio of the rendered image. This is computed automatically and should not be set by the user. |
|
Set/Get the background color of the rendering screen using an rgb color specification. |
|
Set/get a point location in display (or screen) coordinates. The lower left corner of the window is the origin and y increases as you go up the screen. |
|
Specify a function to be called when rendering process completes. Function will be called with argument provided. |
|
Set the arg delete method. This is used to free user memory. |
|
Specify a function to be called before rendering process begins. Function will be called with argument provided. |
|
Set the arg delete method. This is used to free user memory. |
|
Specify a point location in view coordinates. The origin is in the middle of the viewport and it extends from -1 to 1 in all three dimensions. |
|
Specify the viewport for the Viewport to draw in the rendering window. Coordinates are expressed as (xmin,ymin,xmax,ymax), where each coordinate is 0 <= coordinate <= 1.0. |
|
Specify a point location in world coordinates. This method takes homogeneous coordinates. |
|
Convert view coordinates to display coordinates. |
|
Convert view point coordinates to world coordinates. Reimplemented in vtkRenderer. |
|
Convert world point coordinates to display (or screen) coordinates. |
|
Convert world point coordinates to view coordinates. Reimplemented in vtkRenderer. |
