Abstract
It has been a long time since outdoor environments needed a package to avoid unnecessary concern regarding outdoor parameters such as the sun position, sky color and shadows in real-time rendering. An intelligence system is in order to control these main factors for outdoor rendering environments. Calculating and measuring shadows with respect to the sun position in any outdoor rendering environments is a challenging and heavy task. In this paper we try to explore a method of exerting shadows on other objects with respect to the sun position in any given location, date, and time by means of a real-time sky color generation. The sun position makes up an important part of outdoor environments. Sky color is also the main background for any outdoor environments. To create shadows and shadow volumes, stencil buffer and depth buffer are employed. By calculating the sun position in any specific date, time and location, shadow is cast accordingly. Length and angle of shadow are two parameters measured for building designs which are calculated in this real-time application. Therefore, the application can be used to investigate the behavior of the sun position and location of shadows for any outdoor games and outdoor rendering.
