    把网点参数写成.TXT格式,在导光板的TEXTURE中导入就可以在LT 中得到网点,只是中间要有个坐标转换,计算要精解. -ze J#B)C  
    多试几次就可以了.

    lighttools有一個插件叫DXF Tool,可以把autocad的圖檔先轉成DXF檔,然後再吃進去lighttools,也可以把lighttools的網點轉出成dxf檔,讓autocad讀。

    Parameterize the Bumps cQ_Hp <D  
    The Backlight Utility was helpful to build the backlight system quickly. However, `5Zz5V  
    the bumps must be parameterized in order to get the desired output distribution. uFga~&#g  
    You can do this easily using the LightTools Properties dialog box. Eu04e N  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, he hFEyx  
    BottomSurface, and Zones. Then, select Texture, as shown in the following jmW7)jT8:  
    figure. o*hF<D$Y  
    2.Right-click and select Properties on the shortcut menu. b5n'=doR/I  
    3.Select the Geometry tab. )@bQu~Y  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click ]5:8Z@  
    Apply. 8DaL,bi*.

    The default number of bumps is 100 (10 X 10). You need to change these ;sFF+^~L  
    parameters to match your design. Note that LightTools allows many other Nda *L|  
    placement options, but you will use the Bezier placement option for this $PHvA6D  
    example. k"w"hg&e  
    5.On both the X Placement tab and Y Placement tab, change the Number of iOO)Q\  
    Bumps parameter to 300, as shown in the following figure. Click Apply after 9'q*:&qq  
    each change. q> C'BIr  
    6.Click OK to close the dialog box. >[*qf9$  
    Note that the number of bumps is 300 X 300, which results in about 90,000 4+ Z]3oIRE  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a @f_+=}|dc  
    manner defined by the Bezier parameterization option. Please see Chapter 5 of /&94 eC  
    the LightTools Core Module User’s Guide for more information. With the 6)Lk-D  
    current parameter values, the Bezier option varies the bump spacing along the  ; 4~hB  
    length of the light guide. The spacing in the orthogonal direction is constant. 1|wL\I  
    The X and Y refer to the local coordinate system of the surface. pz>>)c`

    1 是autolisp 不是autolist %aVq+kC h  
    2 在autocad中是用autolisp编写插件,实现将网点参数之坐标和半径读取并另存为 VQ9/Gxdeo  
    txt档的命令,只要有坐标和半径就ok了,excel档也无所谓。看你喜欢 lp%pbx43s  
    3 在lighttoools使用texture命令,建立一个圆点的矩阵,在坐标一栏中,把原有的删除 C1 GKLl~  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 6zuTQ^pz  
    4 关键是cad中网点的坐标位置要和lighttools模型的位置对应的上,否则,你贴上去网点位置在离模型很远的地方就不厚道了
