DirectX Lighting vs. Real World Lighting (DX光照 对 真实世界光照) 在DX中,我们能创建不同类型的光,使场景看起来更真实。但要记住,DX中的光只是在近似地模拟自然界的光。在自然界中,光由光源(如灯泡)发出,然后延直线传播,直到消耗完毕或传入眼睛;光在遇到物体时会发生反射,每次反射都会有能量的消耗;实际上,光可以在物体间反射千百万次,而且光滑表面会比不光滑的表面反射更多的光。这一切如果全算进来的话,计算量是巨大的,所以,DX只是在近似地模仿。

water temperature control system uses the Single Chip Microcomputer to carry on temperature real-time gathering and controling. DS18B20, digitized temperature sensor, provides the temperature signal by "a main line". In -10~+85℃ the scope, DS18B20’s inherent measuring accuracy is 0.5 ℃. The water temperature real-time control system uses the electricity nichrome wire carring on temperature increiseament and operates the electric fan to realize the temperature decrease control. The system has the higher measuring accuracy and the control precision, it also can complete the elevation of temperature and the temperature decrease control.
