Detailed Description

OpenGL camera.

vtkExternalOpenGLCamera is a concrete implementation of the abstract class vtkCamera. vtkExternalOpenGLCamera interfaces to the OpenGL rendering library. This class extends vtkOpenGLCamera by introducing API wherein the camera matrices can be set explicitly by the application.

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 vtkOpenGLCamera.

SafeDownCast()

static vtkExternalOpenGLCamera * vtkExternalOpenGLCamera::SafeDownCast ( vtkObjectBase *  o )

static

NewInstanceInternal()

virtual vtkObjectBase * vtkExternalOpenGLCamera::NewInstanceInternal ( ) const

Reimplemented from vtkOpenGLCamera.

NewInstance()

vtkExternalOpenGLCamera * vtkExternalOpenGLCamera::NewInstance

PrintSelf()

void vtkExternalOpenGLCamera::PrintSelf ( ostream &  os, vtkIndent  indent  )

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 vtkCamera.

SetViewTransformMatrix()

void vtkExternalOpenGLCamera::SetViewTransformMatrix

(

const double

elements[16]

)

Set the view transform matrix.

SetProjectionTransformMatrix()

void vtkExternalOpenGLCamera::SetProjectionTransformMatrix

(

const double

elements[16]

)

Set the projection matrix.

ComputeViewTransform()

void vtkExternalOpenGLCamera::ComputeViewTransform ( )

overrideprotectedvirtual

These methods should only be used within vtkCamera.cxx.

Bypass computation if user provided the view transform
