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 vtkVRCamera.

PrintSelf()

void vtkOpenVRCamera::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 vtkOpenGLCamera.

Render()

void vtkOpenVRCamera::Render ( vtkRenderer *  ren )

overridevirtual

Implement base class method.

Reimplemented from vtkOpenGLCamera.

GetKeyMatrices()

void vtkOpenVRCamera::GetKeyMatrices ( vtkRenderer *  ren, vtkMatrix4x4 *&  WCVCMatrix, vtkMatrix3x3 *&  normalMatrix, vtkMatrix4x4 *&  VCDCMatrix, vtkMatrix4x4 *&  WCDCMatrix  )

overridevirtual

Reimplemented from vtkOpenGLCamera.

GetTrackingToDCMatrix()

void vtkOpenVRCamera::GetTrackingToDCMatrix ( vtkMatrix4x4 *&  TCDCMatrix )

overridevirtual

Provides a matrix to go from absolute OpenVR tracking coordinates to device coordinates.

Used for rendering devices.

Implements vtkVRCamera.
