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.

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.

overridevirtual

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.

◆ Render()

void vtkCameraPass::Render ( const vtkRenderState * s )

overridevirtual

Perform rendering according to a render state s.

Precondition: s_exists: s!=0

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

Precondition: w_exists: w!=0

Reimplemented from vtkRenderPass.

◆ GetDelegatePass()

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.

◆ SetDelegatePass()

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 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.
