Abstract: Three dimensional representation of entities is one of the key technigues in visual simulation of Systems. To facilitate the 3D realization of a visual simulation environment Oriented to engineering applications, an integration of various graphical programming techniques can be used. An integration method of VC++, OpenGL and 3DS is used to develop a mining oriented visual simulation application, including the data format of 3DS, the transformation of 3DS data structure into VC++ format, and the 3D representation of entities by OpenGL. Technical details of the integration method are described and some examples of program segments with a visual presentation oriented to mining application are illustrated.
