    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. Wbq0K6X  
    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 wVq9t|V  
    The Backlight Utility was helpful to build the backlight system quickly. However, Q!!u=}GYK  
    the bumps must be parameterized in order to get the desired output distribution. S,s#D9NU  
    You can do this easily using the LightTools Properties dialog box. Bp_8PjQ  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, }BUm}.-{u,  
    BottomSurface, and Zones. Then, select Texture, as shown in the following +MqJJuWB  
    figure. jqj4(J@%yr  
    2.Right-click and select Properties on the shortcut menu. ([dwZ6$/J  
    3.Select the Geometry tab. I.'/!11>  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click >m:n6M'r  
    Apply. 5WA:gygB&

    The default number of bumps is 100 (10 X 10). You need to change these =CW> ;h]  
    parameters to match your design. Note that LightTools allows many other L]%!YP\<T  
    placement options, but you will use the Bezier placement option for this Ai"MJ6)  
    example. ;.Ld6JRunw  
    5.On both the X Placement tab and Y Placement tab, change the Number of tLU@&NY`  
    Bumps parameter to 300, as shown in the following figure. Click Apply after Eyz.^)r  
    each change. ff7#LeB9  
    6.Click OK to close the dialog box. TNckyP75u  
    Note that the number of bumps is 300 X 300, which results in about 90,000  gnkeJ}K  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a { P,hH~!  
    manner defined by the Bezier parameterization option. Please see Chapter 5 of F!phTu  
    the LightTools Core Module User’s Guide for more information. With the "TP~TjXfq  
    current parameter values, the Bezier option varies the bump spacing along the bIlNA)g  
    length of the light guide. The spacing in the orthogonal direction is constant. p>i8aN  
    The X and Y refer to the local coordinate system of the surface. pN)x,<M)

    You might be curious as to why you cannot see the 3D texture property zones you *N4/M%1P

    1 是autolisp 不是autolist d1\nMm}v  
    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 xl`AiO `K  
    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 ]"HaE-`%  
    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 & nXE?-J  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 (m,H 5  
    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
