    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. rf$X>M=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 KW7UUXL  
    The Backlight Utility was helpful to build the backlight system quickly. However, p3}?fej&|  
    the bumps must be parameterized in order to get the desired output distribution. D3x/OyG(  
    You can do this easily using the LightTools Properties dialog box. 8dlw-Q'S  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, E(i[o?  
    BottomSurface, and Zones. Then, select Texture, as shown in the following "t0kAG  
    figure. ts8+V<g  
    2.Right-click and select Properties on the shortcut menu. NVl [kw  
    3.Select the Geometry tab.  <Tot|R;  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click Q(o!iI:Gts  
    Apply. 84{Q\c

    The default number of bumps is 100 (10 X 10). You need to change these v{ <[)cr  
    parameters to match your design. Note that LightTools allows many other ~xIj F1Z  
    placement options, but you will use the Bezier placement option for this WX4;l(P L=  
    example. (7DXRcr<  
    5.On both the X Placement tab and Y Placement tab, change the Number of "Y=+Ls(3o(  
    Bumps parameter to 300, as shown in the following figure. Click Apply after DS xUdEK6  
    each change. pDh se2  
    6.Click OK to close the dialog box. mw^7oO#  
    Note that the number of bumps is 300 X 300, which results in about 90,000 J# kl 7  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a dXn%lJ  
    manner defined by the Bezier parameterization option. Please see Chapter 5 of *x>3xQq&  
    the LightTools Core Module User’s Guide for more information. With the 9,]5v +  
    current parameter values, the Bezier option varies the bump spacing along the *{o UWt  
    length of the light guide. The spacing in the orthogonal direction is constant. A%\tiZe  
    The X and Y refer to the local coordinate system of the surface. C_LvZ=

    Using the methods described in previous chapters, you may want to check your iK_c.b  
    model before you run a simulation. kVS?RHR  
    Click on various parts of the model in the 3D Design View. Or use the System AD('=g J  
    Navigator to select different surfaces and view their Properties. i.1U|Pi  
    1.In the System Navigator, click to open BottomSurface of the LightGuide, then 2yo cu!4l  
    click Zones, and then click Texture. P6U%=xaC  
    2.Select SphericalElement, and then right-click and select Properties from the zX7q:Pt  
    shortcut menu. The Shape tab shows you a graphical representation of the r(2 R <A  
    spherical bump shape that is the bottom of the light guide. PKq-@F%X  
    You might be curious as to why you cannot see the 3D texture property zones you 8n?kZY$,  
    defined. They are invisible by default, because drawing thousands of texture (!?K7<Jv  
    elements can make displaying and exploring the model somewhat slow. If you f0Hq8qAF;^  
    choose to make them visible, 3D textures are displayed in wireframe, even if the pz doqAVI  
    display mode is set to translucent. Wireframe rendering displays a bit faster and F:37MUQi  
    shows more of the technical details. l!IKUzt)7

    1 是autolisp 不是autolist >a9l>9fyY  
    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 {]M>Y%j48  
    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 :A*0]X;  
    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 _ _ =s'  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 `]hCUaV   
    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
