Detailed Description
abstract specification for renderers
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.

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. To disable this mode, turn the interactor's LightFollowCamera flag OFF, and leave the renderer's LightFollowCamera flag ON.)

| void vtkRenderer::ResetCamera | ( | ) |
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.
| void vtkRenderer::ResetCamera | ( | double | 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.

Set/Get the layer that this renderer belongs to. This is only used if there are layered renderers. Note: Changing the layer will update the PreserveColorBuffer setting. If the layer is 0, PreserveColorBuffer will be set to false, making the bottom renderer opaque. If the layer is non-zero, PreserveColorBuffer will be set to true, giving the renderer a transparent background. If other PreserveColorBuffer configurations are desired, they must be adjusted after the layer is set.

By default, the renderer at layer 0 is opaque, and all non-zero layer renderers are transparent. This flag allows this behavior to be overridden. If true, this setting will force the renderer to preserve the existing color buffer regardless of layer. If false, it will always be cleared at the start of rendering. This flag influences the Transparent() method, and is updated by calls to SetLayer(). For this reason it should only be set after changing the layer.

Ask all props to update and draw any translucent polygonal geometry. This includes both vtkActors and vtkVolumes Return the number of rendered props. It is called once with alpha blending technique. It is called multiple times with depth peeling technique.

Ask the active camera to do whatever it needs to do prior to rendering. Creates a camera if none found active.

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).

Specifies the minimum distance of the near clipping plane as a percentage of the far clipping plane distance. Values below this threshold are clipped to NearClippingPlaneTolerance*range[1]. Note that values which are too small may cause problems on systems with low z-buffer resolution.

When this flag is off, the renderer will not erase the background or the Zbuffer. It is used to have overlapping renderers. Both the RenderWindow Erase and Render Erase must be on for the camera to clear the renderer. By default, Erase is on.

If this flag is on and the GPU supports it, depth peeling is used for rendering translucent materials. If this flag is off, alpha blending is used. Initial value is off.

In case of use of depth peeling technique for rendering translucent material, define the threshold under which the algorithm stops to iterate over peel layers. This is the ratio of the number of pixels that have been touched by the last layer over the total number of pixels of the viewport area. Initial value is 0.0, meaning rendering have to be exact. Greater values may speed-up the rendering with small impact on the quality.
Definition at line 653 of file vtkRenderer.h.

In case of depth peeling, define the maximum number of peeling layers. Initial value is 4. A special value of 0 means no maximum limit. It has to be a positive value.

Tells if the last call to DeviceRenderTranslucentPolygonalGeometry() actually used depth peeling. Initial value is false.
