    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. ,tak{["  
    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 v(zfq'^%`  
    The Backlight Utility was helpful to build the backlight system quickly. However, ydMSL25<+  
    the bumps must be parameterized in order to get the desired output distribution. R#ZO<g%'  
    You can do this easily using the LightTools Properties dialog box. lYS*{i1^ '  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, Xn02p,,  
    BottomSurface, and Zones. Then, select Texture, as shown in the following u{S"NEc  
    figure. 7m8(8$-6  
    2.Right-click and select Properties on the shortcut menu. p$mt&,p  
    3.Select the Geometry tab. 1 0^FfwRfM  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click & l0LW,Bx

    The default number of bumps is 100 (10 X 10). You need to change these }=|plz}  
    parameters to match your design. Note that LightTools allows many other xNjWo*y v  
    placement options, but you will use the Bezier placement option for this Zgo%Jo  
    example. I3u)y|Y=  
    5.On both the X Placement tab and Y Placement tab, change the Number of D 4sp+   
    Bumps parameter to 300, as shown in the following figure. Click Apply after Z1.v%"/(  
    each change. }b]eiPWN  
    6.Click OK to close the dialog box. `1uGU[{x  
    Note that the number of bumps is 300 X 300, which results in about 90,000 ;,s9jw  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a ZEso2|   
    manner defined by the Bezier parameterization option. Please see Chapter 5 of @M"( r"ab  
    the LightTools Core Module User’s Guide for more information. With the -q\Rbb5M  
    current parameter values, the Bezier option varies the bump spacing along the je%D&ci$  
    length of the light guide. The spacing in the orthogonal direction is constant. -b|"%e<'  
    The X and Y refer to the local coordinate system of the surface. qfjUJ/

    You might be curious as to why you cannot see the 3D texture property zones you S&QXf<v  
    defined. They are invisible by default, because drawing thousands of texture zRbY]dW  
    elements can make displaying and exploring the model somewhat slow. If you `YqXF=-  
    choose to make them visible, 3D textures are displayed in wireframe, even if the pw`'q(ad  
    display mode is set to translucent. Wireframe rendering displays a bit faster and 6b9J3~d\E

    1 是autolisp 不是autolist =5Nh}o(l?  
    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 g6;smtu_T  
    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 nj1o!+9>$  
    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 UoKVl-  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 [0aC]XQZ  
    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
