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.

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.

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 ( vtkObjectBase * o ) [static]

Reimplemented from vtkRenderPass.

virtual vtkObjectBase* vtkCompositeZPass::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkRenderPass.

vtkCompositeZPass* vtkCompositeZPass::NewInstance ( ) const

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.
