/**

|
* @class vtkRenderStepsPass
|
|
* @brief Execute render passes sequentially.
|
|
*
|
|
* vtkRenderStepsPass executes a standard list of render passes sequentially.
|
|
* This class allows to define a sequence of render passes at run time.
|
|
* You can set a step to NULL in order to skip that step. Likewise you
|
|
* can replace any of the default steps with your own step. Typically in
|
|
* such a case you would get the current step, replace it with your own
|
|
* and likely have your step call the current step as a delegate. For example
|
|
* to replace the translucent step with a depthpeeling step you would get the
|
|
* current tranlucent step and set it as a delegate on the depthpeeling step.
|
|
* Then set this classes translparent step to the depthpeelnig step.
