Detailed Description

tracks state of OpenGL model-view and projection matrices.

vtkOpenGLModelViewProjectionMonitor – A helper for painters that tracks state of OpenGL model-view and projection matrices. A Painter could use this to skip expensive processing that is only needed when the model-view or projection matrices 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 vtkObjectBase.

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.

bool vtkOpenGLModelViewProjectionMonitor::StateChanged ( )

Fetches the current GL state and updates the internal copies of the data.

returns true if any of the tracked OpenGL matrices have changed. Typically this is the only function a user needs to call.

void vtkOpenGLModelViewProjectionMonitor::Update ( )

Fetch and store OpenGL model view matrix.

Note, this is done automatically in SateChanged.

void vtkOpenGLModelViewProjectionMonitor::SetProjection ( float * val )

Set the matrix data.

void vtkOpenGLModelViewProjectionMonitor::SetModelView ( float * val )

Set the matrix data.
