5.3 Example Graphs
Microsoft DirectX SDK provides a very useful debugging utility -
GraphEdit, which can be used to simulate graph building. From
the Graph menu of the GraphEdit application, click Insert Fil-
ters… and choose the filters required. Filters are organized by
categories. Click Insert Filter to add filters to a graph. Connect the
two filters’ pins by dragging the mouse from one filter’s output pin
to another filter’s input pin. An arrow will be drawn if these two pins
agree on the connection.
