Direct light is better for reading than diffuse light.

直射光比漫射光更有利阅读。

Based on the emission, absorption, diffusion, reflection and scatteration of light by a voxel, it is suitable for generating and rendering realistic images of complex scenes.

基对光线的发射、吸收、漫射、反射和散射基础上的放射法,适用复杂景物的生成和演示,在真实感图形演示中具有重要地位。
