[Multimedia Develop] OpenGL-sunaearth DL : 0: 以太阳、地球作为例子，把太阳作为光源，模拟地球围绕太阳转动时光照的变化。于是，需要设置一个光源——太阳，设置两种材质——太阳的材质和地球的材质。把太阳光线设置为白色，位置在画面正中。把太阳的材质设置为微微散发出红色的光芒，把地球的材质设置为微微散发出暗淡的蓝色光芒，并且反射蓝色的光芒，镜面指数设置成一个比较小的值。简单起见，不再考虑太阳和地球的大小关系，用同样大小的球体来代替之。 -In the sun, the Earth as an example, the sun as a light source, simulate the Earth rotation around the sun light changes. Thus, the need to set up a light source- the sun, setting two materials- the sun and the Earth material material. The sun s rays to white, middle position in the frame. The material of the sun setting slightly exudes red light, the earth material to emit a slightly dim blue light and reflects blue light, mirror the index is set to a relatively small value. For simplicity, no longer consider the relationship between the Sun and Earth s size, with the same size of a sphere instead.
