vtkRenderPass Class Reference
#include <vtkRenderPass.h>
Detailed Description
Perform part of the rendering of a vtkRenderer.vtkRenderPass is a deferred class with a simple deferred method Render. This method performs a rendering pass of the scene described in vtkRenderState. Subclasses define what really happens during rendering.
Directions to write a subclass of vtkRenderPass: It is up to the subclass to decide if it needs to delegate part of its job to some other vtkRenderPass objects ("delegates").
- The subclass has to define ivar to set/get its delegates.
- The documentation of the subclass has to describe:
- what each delegate is supposed to perform
- if a delegate is supposed to be used once or multiple times
- what it expects to have in the framebuffer before starting (status of colorbuffers, depth buffer, stencil buffer)
- what it will change in the framebuffer.
- A pass cannot modify the vtkRenderState where it will perform but it can build a new vtkRenderState (it can change the FrameBuffer, change the prop array, changed the required prop properties keys (usually adding some to a copy of the existing list) but it has to keep the same vtkRenderer object), make it current and pass it to its delegate.
- at the end of the execution of Render, the pass has to ensure the current vtkRenderState is the one it has in argument.

| static int vtkRenderPass::IsTypeOf | ( | const char * | name | ) | [static] |
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.
