Detailed Description

Implement the camera render pass.

Render the camera.

It setups the projection and modelview matrices and can clear the background It calls its delegate once. After its delegate returns, it restore the modelview matrix stack.

Its delegate is usually set to a vtkSequencePass with a vtkLigthsPass and a list of passes for the geometry.

Member Typedef Documentation

typedef vtkRenderPass vtkCameraPass::Superclass

Reimplemented from vtkRenderPass.

Definition at line 43 of file vtkCameraPass.h.

Constructor & Destructor Documentation

vtkCameraPass::vtkCameraPass ( ) [protected]

Used to override the aspect ratio used when computing the projection matrix. This is useful when rendering for tile-displays for example.

virtual vtkCameraPass::~vtkCameraPass ( ) [protected, virtual]

Destructor.

Member Function Documentation

static vtkCameraPass* vtkCameraPass::New ( ) [static]

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

Reimplemented from vtkObject.

virtual const char* vtkCameraPass::GetClassName ( ) [virtual]

Reimplemented from vtkRenderPass.

static int vtkCameraPass::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 vtkCameraPass::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 vtkCameraPass* vtkCameraPass::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkRenderPass.

void vtkCameraPass::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 vtkCameraPass::Render ( const vtkRenderState * s ) [virtual]

Perform rendering according to a render state s.

Precondition:: s_exists: s!=0

Implements vtkRenderPass.

void vtkCameraPass::ReleaseGraphicsResources ( vtkWindow * w ) [virtual]

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

Precondition:: w_exists: w!=0

Reimplemented from vtkRenderPass.

virtual vtkRenderPass* vtkCameraPass::GetDelegatePass ( ) [virtual]

Delegate for rendering the geometry. If it is NULL, nothing will be rendered and a warning will be emitted. It is usually set to a vtkSequencePass with a vtkLigthsPass and a list of passes for the geometry. Initial value is a NULL pointer.

virtual void vtkCameraPass::SetDelegatePass ( vtkRenderPass * delegatePass ) [virtual]

Delegate for rendering the geometry. If it is NULL, nothing will be rendered and a warning will be emitted. It is usually set to a vtkSequencePass with a vtkLigthsPass and a list of passes for the geometry. Initial value is a NULL pointer.

virtual void vtkCameraPass::SetAspectRatioOverride ( double ) [virtual]

Used to override the aspect ratio used when computing the projection matrix. This is useful when rendering for tile-displays for example.

virtual double vtkCameraPass::GetAspectRatioOverride ( ) [virtual]

Used to override the aspect ratio used when computing the projection matrix. This is useful when rendering for tile-displays for example.

virtual void vtkCameraPass::GetTiledSizeAndOrigin	(	const vtkRenderState *	render_state,
		int *	width,
		int *	height,
		int *	originX,
		int *	originY
	)			`[protected, virtual]`
