Unlike other established graphics standards such as OpenGL and Direct3D it does not provide primitive drawing routines, instead it provides direct access to pixel memory so that any type of custom rendering can be performed. This makes PTC ideal for programmers who either have to or want to write their own rendering routines. Some examples of applications where this can apply includes software 2D and 3D renderers, games, demos, emulators and any other application that performs custom rendering or pixel manipulation. If however, all that an application requires is a fast set of basic rendering primitives, for example a computer game targeting hardware 3D accelerated platforms, then PTC is not the best choice. PTC does not, and will not provide this functionality. If this is what you are looking for then i suggest you take a look at OpenGL instead."
