This paper describes the implementation of Direct3D interface library for Python language. DirectX is the most popular library used for 3D games and 3D modelings. However, softwares which use the library can only be developed in the environments provided by Microsoft like Visual Studios and .NET framework. The interface module for Python, this paper presents, will extend the coverage of the useful library DirectX to a language which is not fully supported by Microsoft. The interface techniques described here can be a guide to develop interface modules for other languages too, which make their language more powerful and extensible. This paper describes the implementation techniques to develop the interface module for Python, advantages and disadvantages.
