不是“Use multi-level boxing to speed up ray tracing”，而是“Use multiple reflections”，UserManual上有：“the g| <wyt[  
Number of reflections must be at least 2 to calculate the scattering K4Dp:2/K%  
from a dihedral and at least 3 for a trihedral.”计算二面角反射次数至少为2，三面角反射次数至少要设为3，以前没仔细看啊，呵呵。 !9iGg*0dx

Use multiple reflections: When this item is checked, multiple reflections are considered for the ray tracing. The number of reflections that must be considered is set in the Number of reflections dialog. This parameter determines the number of reflections to be taken into account for triangles with labels in the specified range. (For example, theNumber of reflections must be at least 2 to calculate the scattering from a dihedral and at least 3 for a trihedral.) Increasing the number of reflections that must be considered significantly increases computation time, and this should only be done based on physical considerations.

二面角属于物理光学二次反射问题，呵呵！

发现了好东西，学习学习。
