Detailed Description

tracks state of OpenGL model-view and projection matrices.

vtkOpenGLLightMonitor – A helper for painters that tracks state of OpenGL lights. A Painter could use this to skip expensive processing that is only needed when lights change.

this is not intended to be shared. each object should use it's own instance of this class. it's intended to be called once per render.

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 vtkObject.

void vtkOpenGLLightMonitor::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 vtkObject.

virtual void vtkOpenGLLightMonitor::SetLightId ( int  )

virtual

Set/Get the light id of the OpenGL light to track. The light id must be set prior to use. Default value 0.

virtual int vtkOpenGLLightMonitor::GetLightId ( )

virtual

Set/Get the light id of the OpenGL light to track. The light id must be set prior to use. Default value 0.

bool vtkOpenGLLightMonitor::StateChanged

(

)

Fetches the current GL state and updates the internal copies of the data. returns true if any of the tracked OpenGL lights have changed. Typically this is the only function a user needs to call.

void vtkOpenGLLightMonitor::Update

(

)

Fetch and save OpenGL light state. Note, this is done automatically in SateChanged.

void vtkOpenGLLightMonitor::SetEnabled

(

int

val

)

Setters for internal state.
