PngComponents is a set of components that allows you to include in your application real PNG files. PNG files on their own do not generate an enourmous advantage, but their support for an alpha-channel does indeed have quite a charm to it. The PngComponents library supports alpha-channels to their full extend, using a modified version of the excellent pngdelphi library.

Our libraries can run in WPF and WinForms applications. The libraries are using WPF 3D rendering engine from .Net 4.0 (or 3.5 SP1). The engine does not provide all the features of DirectX and is not capable of running high end 3D games. But our customers have already proven that it is very capable of showing quite complex 3D scenes with models with several hundred thousands triangles.
