Topic: To make from WinAPI\DirectX applications "works natively in WPF"

All greetings the Sense such, at me is a certain graphic application on WinAPI\C ++ which uses DirectX 9 for rendering in a window. I need to make on its basis wpf a component, which works natively in WPF. I.e.  not in a window, and in this component which (probably) can be allocated arbitrary on forms. From what side to approach to the task? Someone can advises a sample \article with the decision? I while  D3DImage a component. But can eat more correct ways?
