材质与光源的关系例程

以上程序运行结果是一个蓝色的球，其中高光部分仍为上一例的亮紫色。从上可看出，球漫反射光的结果是mat_diffuse[]与light_diffuse[]中的三个颜色分量值相乘，即 (0.0*1.0,0.0*1.0,0.8*1.0,1.0*1.0)=(0.0,0.0,0.8,1.0)，所以球大部分呈现蓝色。-Light shows the relationship between materials and light sources for more than routine run result is a blue ball, which is still on the case of high light some of the bright purple. As can be seen from the ball a result of diffuse reflected light mat_diffuse [] and light_diffuse [] in the sub-value multiplied by three colors, namely, (0.0* 1.0,0.0* 1.0,0.8* 1.0,1.0* 1.0) = ( 0.0,0.0,0.8,1.0), so the ball most of the blue color.
