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.

◆ ReleaseCurrentShader()

Release the current shader.

Basically go back to having no shaders loaded. This is useful for old legacy code that relies on no shaders being loaded.

Free up any resources being used by the provided shader.
