چکیده:

This paper presents an approach towards the construction of visual system software of a full motion-vision flight simulator of a helicopter. The parincipal intention in this approach is to generate a photorealistic, real-time, productive and deminstrative virtual environment. As a matter of fact, all aspects have been influenced by factual restrictions in achievement of hardwares and funds. Subsequently the optimal assortment of hardwares, operating system and development platform, algorithms, programming techniques and creating of the 3D Graphics Engine, in this activity are inevitable. The state of the art of this activity is an awkward lighting and shading technique. This scheme has been implemented by the most efficient texture and color blending schemes. Here we have exploited the different Texture Factors in order to generate visuale effects of dawn, dusk, day and night. As a matter of fact, such kinds of lighting and shading approaches as Direct3D Lighting or the pixel and vertex shading techniques, have been thrown away.
