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。 -DirectX Lighting vs. Real World Lighting (DX light illumination of the real world) in the DX, we can create different types of light, to make scenes look more realistic. Bear in mind, however, DX in the light only in the approximation to simulate natural light. In nature, light from light source (such as light bulbs) to issue, and then the extension of a straight line, until the consumption of finished or imported into the eyes-ray object in the face of reflection will occur, each reflection will have energy consumption in fact, light can be inter-reflection in the object of millions of times, and the smooth surface than the non-smooth surface reflects more light. All full-count in. If so, computation is enormous, so, DX only approximate
