    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. SANb g&$  
    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 v49 i.c9  
    The Backlight Utility was helpful to build the backlight system quickly. However, Ox aS<vQ3  
    the bumps must be parameterized in order to get the desired output distribution. o}D7 $6  
    You can do this easily using the LightTools Properties dialog box. v9D[| 4  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, .p~.S&)  
    BottomSurface, and Zones. Then, select Texture, as shown in the following dKPx3Y'  
    figure. 3\B~`=*q/  
    2.Right-click and select Properties on the shortcut menu. *:chN' <  
    3.Select the Geometry tab. PB:r+[91  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click r_V^sX  
    Apply. ]#rmk!VT?

    The default number of bumps is 100 (10 X 10). You need to change these ?l 0WuU  
    parameters to match your design. Note that LightTools allows many other S.fb[gI]  
    placement options, but you will use the Bezier placement option for this erV&N,cI  
    example. \D! I"mr  
    5.On both the X Placement tab and Y Placement tab, change the Number of 1Dm$:),^T}  
    Bumps parameter to 300, as shown in the following figure. Click Apply after I"jub kI=Z  
    each change. Wc/B_F?2  
    6.Click OK to close the dialog box. I\6^]pi,  
    Note that the number of bumps is 300 X 300, which results in about 90,000 ;uU 8$  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a 38RyUHL=  
    manner defined by the Bezier parameterization option. Please see Chapter 5 of XCO;t_%  
    the LightTools Core Module User’s Guide for more information. With the VC NQ}h[D  
    current parameter values, the Bezier option varies the bump spacing along the &Mh]s\  
    length of the light guide. The spacing in the orthogonal direction is constant. p:4oA<V  
    The X and Y refer to the local coordinate system of the surface. `[4{]jX+<

    Using the methods described in previous chapters, you may want to check your OmECvL'Z  
    model before you run a simulation. l9$"zEC  
    Click on various parts of the model in the 3D Design View. Or use the System L q;=UE  
    Navigator to select different surfaces and view their Properties. iC<qWq|S_m  
    1.In the System Navigator, click to open BottomSurface of the LightGuide, then ~w$ ^`e!]  
    click Zones, and then click Texture. gs=(h*  
    2.Select SphericalElement, and then right-click and select Properties from the wb-_CQ  
    shortcut menu. The Shape tab shows you a graphical representation of the 0a's[>-'A  
    spherical bump shape that is the bottom of the light guide. nA#dXckoc  
    You might be curious as to why you cannot see the 3D texture property zones you $C&E3 'O  
    defined. They are invisible by default, because drawing thousands of texture EYKV}`  
    elements can make displaying and exploring the model somewhat slow. If you y)+l U  
    choose to make them visible, 3D textures are displayed in wireframe, even if the HS 1zA  
    display mode is set to translucent. Wireframe rendering displays a bit faster and >VvA&p71b  
    shows more of the technical details. \w@ "`!%

    1 是autolisp 不是autolist MPD<MaW$  
    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 R>n=_C  
    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 K+ @R [  
    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 =/MA`>  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 gX!-s*{E  
    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
