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.

double vtkRenderer::NearClippingPlaneTolerance [protected]
 

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.

int vtkRenderer::Erase [protected]
 

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.
