I suggest you use pure WPF 3D capabilities instead.It is not clear why using interoperability (System.Windows.Interop.D3DImage). However, if your still need it (legacy or other reasons), you need to show your code.—SA

The good news: it can be done. The bad news: A precise test is computationally expensive and therefore probably too slow to be of any use in real time rendering.First off, it works only on convex objects. Concave objects would have to be broken down into two or more convex objects and then...
