vtkRenderer provides an abstract specification for renderers. A renderer 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. vtkRenderer 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 an culler to the list of cullers. |
|
Add a light to the list of lights. |
|
Clear the image to the background color. Reimplemented in vtkMesaRenderer. |
|
Compute the bounding box of all the visible props Used in ResetCamera() and ResetCameraClippingRange() |
|
Create and add a light to renderer. |
|
Create an image. Subclasses of vtkRenderer must implement this method. Implemented in vtkMesaRenderer. |
|
Get the current camera. |
|
Return any actors in this renderer. |
|
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 vtkViewport. Reimplemented in vtkMesaRenderer. |
|
Return the collection of cullers. |
|
Get the time required, in seconds, for the last Render call. |
|
Return the collection of lights. |
|
Return the MTime of the renderer also considering its ivars. Reimplemented from vtkObject. |
|
Should be used internally only during a render Get the number of props that were rendered using a RenderOpaqueGeometry or RenderTranslucentGeometry call. This is used to know if something is in the frame buffer. |
|
Return the RayCaster being used by this renderer. |
|
Get the ratio between allocated time and actual render time. |
|
Turn on/off two-sided lighting of surfaces. If two-sided lighting is off, then only the side of the surface facing the light(s) will be lit, and the other side dark. If two-sided lighting on, both sides of the surface will be lit. |
|
Return the collection of volumes. |
|
Return the vtkWindow that owns this vtkViewport. Implements vtkViewport. |
|
Given a pixel location, return the Z value |
|
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 vtkViewport. Reimplemented in vtkMesaRenderer. |
|
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 vtkViewport. Reimplemented in vtkMesaRenderer. |
|
Create a vtkRenderer with a black background, a white ambient light, two-sided lighting turned on, a viewport of (0,0,1,1), and backface culling turned off. Reimplemented from vtkObject. Reimplemented in vtkMesaRenderer. |
|
Return the prop (via a vtkAssemblyPath) 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 nothing was picked then NULL is returned. This method selects from the renderers Prop list. Implements vtkViewport. |
|
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 vtkViewport. Reimplemented in vtkMesaRenderer. |
|
Remove an actor from the list of cullers. |
|
Remove a light from the list of lights. |
|
Create an image. This is a superclass method which will in turn call the DeviceRender method of Subclasses of vtkRenderer |
|
Render the overlay actors. This gets called from the RenderWindow because it may need to be synchronized to happen after the buffers have been swapped. |
|
Alternative version of ResetCamera(bounds[6]); |
|
Automatically set up the camera based on a specified bounding box (xmin,xmax, ymin,ymax, zmin,zmax). Camera will reposition itself so that its focal point is the center of the bounding box, and adjust its distance and position to preserve its initial view plane normal (i.e., vector defined from camera position to focal point). Note: is the view plane is parallel to the view up axis, the view up axis will be reset to one of the three coordinate axes. |
|
Automatically set up the camera based on the visible actors. The camera will reposition itself to view the center point of the actors, and move along its initial view plane normal (i.e., vector defined from camera position to focal point) so that all of the actors can be seen. |
|
Reset the camera clipping range based on a bounding box. This method is called from ResetCameraClippingRange() |
|
Reset the camera clipping range based on the bounds of the visible actors. This ensures that no props are cut off |
|
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 vtkViewport. Reimplemented in vtkMesaRenderer. |
|
Specify the camera to use for this renderer. |
|
Set/Get the amount of time this renderer is allowed to spend rendering its scene. This is used by vtkLODActor's. |
|
Set the intensity of ambient lighting. |
|
Turn on/off using backing store. This may cause the re-rendering time to be slightly slower when the view changes. But it is much faster when the image has not changed, such as during an expose event. |
|
Turn on/off interactive status. An interactive renderer is one that can receive events from an interactor. Should only be set if there are multiple renderers in the same section of the viewport. |
|
Set/Get the layer that this renderer belongs to. This is only used if there are layered renderers. |
|
Turn on/off the automatic repositioning of lights as the camera moves. If LightFollowCamera is on, lights that are designated as Headlights or CameraLights will be adjusted to move with this renderer's camera. If LightFollowCamera is off, the lights will not be adjusted. (Note: In previous versions of vtk, this light-tracking functionality was part of the interactors, not the renderer. For backwards compatibility, the older, more limited interactor behavior is enabled by default. This mode has the possibly unexpected property of turning the first light into a headlight, no matter what its light type is. To disable this mode, turn the interactor's LightFollowCamera flag OFF, and leave the renderer's LightFollowCamera flag ON.) |
|
Specify the rendering window in which to draw. This is automatically set when the renderer is created by MakeRenderer. The user probably shouldn't ever need to call this method. |
|
Returns a boolean indicating if this renderer is transparent. It is transparent if it is not in the deepest layer of its render window. |
|
Detects reference loop renderer<->rayCaster Reimplemented from vtkObject. |
|
Ask the active camera to do whatever it needs to do prior to rendering. Creates a camera if none found active. |
|
Ask all props to update and draw any opaque and translucent geometry. This includes both vtkActors and vtkVolumes Returns the number of props that rendered geometry. |
|
Update the geometry of the lights in the scene that are not in world space (for instance, Headlights or CameraLights that are attached to the camera). |
|
Ask all lights to load themselves into rendering pipeline. This method will return the actual number of lights that were on. Reimplemented in vtkMesaRenderer. |
|
Convert view point coordinates to world coordinates. Reimplemented from vtkViewport. |
|
Returns the number of visible actors. |
|
Returns the number of visible volumes. |
|
Convert world point coordinates to view coordinates. Reimplemented from vtkViewport. |
|
