From SpinnerBaker Software:
MeshX is a 3D modelling program, for creating, viewing, editing, and saving DirectX X files. It can be used to create and edit models for 3D programming, or just to create great 3D art. Since MeshX uses DirectX for loading and rendering X files, there's no conversion involved, so when you save to file, what you see really is what you get. There are three lights which you can move and adjust, and you can capture the DirectX window to an image file at any time.
