vtkDepthImageProcessingPass()
Default constructor.
virtual void RenderDelegate(const vtkRenderState *s, int width, int height, int newWidth, int newHeight, vtkFrameBufferObject *fbo, vtkTextureObject *colortarget, vtkTextureObject *depthtarget)
Render delegate with a image of different dimensions than the original one.
void ReadWindowSize(const vtkRenderState *s)
Read parent size - for sake of code clarity This function is generic, can be useful in multiple image...
void PrintSelf(ostream &os, vtkIndent indent)
Methods invoked by print to print information about the object including superclasses.
virtual void SetDelegatePass(vtkRenderPass *delegatePass)
virtual ~vtkDepthImageProcessingPass()
Destructor.
void ReleaseGraphicsResources(vtkWindow *w)
Release graphics resources and ask components to release their own resources.
