Detailed Description

Merge depth buffers of processes.

Merge the depth buffers of satellite processes into the root process depth buffer. It assumes that all the depth buffers have the same number of bits. The depth buffer of the satellite processes are not changed.

This pass requires a OpenGL context that supports texture objects (TO), and pixel buffer objects (PBO). If not, it will emit an error message and will render its delegate and return.

Constructor & Destructor Documentation

vtkCompositeZPass::vtkCompositeZPass ( )
protected

virtual vtkCompositeZPass::~vtkCompositeZPass ( )
protectedvirtual

Destructor.


Member Function Documentation

static vtkCompositeZPass* vtkCompositeZPass::New ( )
static

Create an object with Debug turned off, modified time initialized to zero, and reference counting on.

Reimplemented from vtkObject.

virtual const char* vtkCompositeZPass::GetClassName ( )
virtual

Reimplemented from vtkRenderPass.

static int vtkCompositeZPass::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.

Reimplemented from vtkRenderPass.

virtual int vtkCompositeZPass::IsA ( const char *  name)
virtual

Return 1 if this class 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.

Reimplemented from vtkRenderPass.

static vtkCompositeZPass* vtkCompositeZPass::SafeDownCast ( vtkObject o)
static

Reimplemented from vtkRenderPass.

void vtkCompositeZPass::PrintSelf ( ostream &  os,
vtkIndent  indent 
)
virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkRenderPass.

virtual void vtkCompositeZPass::Render ( const vtkRenderState s)
virtual

Perform rendering according to a render state s.

Precondition:
s_exists: s!=0

Implements vtkRenderPass.

void vtkCompositeZPass::ReleaseGraphicsResources ( vtkWindow w)
virtual

Release graphics resources and ask components to release their own resources.

Precondition:
w_exists: w!=0

Reimplemented from vtkRenderPass.

virtual vtkMultiProcessController* vtkCompositeZPass::GetController ( )
virtual

Controller If it is NULL, nothing will be rendered and a warning will be emitted. Initial value is a NULL pointer.

virtual void vtkCompositeZPass::SetController ( vtkMultiProcessController controller)
virtual

Controller If it is NULL, nothing will be rendered and a warning will be emitted. Initial value is a NULL pointer.

bool vtkCompositeZPass::IsSupported ( vtkOpenGLRenderWindow context)

Is the pass supported by the OpenGL context?

void vtkCompositeZPass::CreateProgram ( vtkOpenGLRenderWindow context)
protected

Create program for texture mapping.

Precondition:
context_exists: context!=0
Program_void: this->Program==0
Postcondition:
Program_exists: this->Program!=0
