    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. OG~gFZr)6  
    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 =J==i?  
    The Backlight Utility was helpful to build the backlight system quickly. However, &B;~  
    the bumps must be parameterized in order to get the desired output distribution. wm@@$  
    You can do this easily using the LightTools Properties dialog box. G>=*yqo  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, ?<,l3pwqa  
    BottomSurface, and Zones. Then, select Texture, as shown in the following **0~K";\  
    figure. Wi<m{.%\E  
    2.Right-click and select Properties on the shortcut menu. ]q[D>6_  
    3.Select the Geometry tab. aK~8B_5k8  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click ]A `n( "%  
    Apply. @bLy,Xr&

    The default number of bumps is 100 (10 X 10). You need to change these D) P._?  
    parameters to match your design. Note that LightTools allows many other S@tLCqV4  
    placement options, but you will use the Bezier placement option for this >6-`}G+|  
    example. G4;Oi=  
    5.On both the X Placement tab and Y Placement tab, change the Number of 6_;icpN]  
    Bumps parameter to 300, as shown in the following figure. Click Apply after 4"ZP 'I;  
    each change. S13nL^=i  
    6.Click OK to close the dialog box. a-tmq]]E  
    Note that the number of bumps is 300 X 300, which results in about 90,000 #X$\&,Yn"  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a {S \{Ii6  
    manner defined by the Bezier parameterization option. Please see Chapter 5 of DCa^ u'f  
    the LightTools Core Module User’s Guide for more information. With the =svN#q5s  
    current parameter values, the Bezier option varies the bump spacing along the H8jpxzXv  
    length of the light guide. The spacing in the orthogonal direction is constant. y.k~Y0  
    The X and Y refer to the local coordinate system of the surface. 4_lrg|X1

    Using the methods described in previous chapters, you may want to check your o-HT1Hc!  
    model before you run a simulation. 0mVNQxHI  
    Click on various parts of the model in the 3D Design View. Or use the System ="H%6S4'  
    Navigator to select different surfaces and view their Properties. HiFUv>,u  
    1.In the System Navigator, click to open BottomSurface of the LightGuide, then H?Wya.7  
    click Zones, and then click Texture. gH vZVC[b  
    2.Select SphericalElement, and then right-click and select Properties from the @mBQ?; qlK  
    shortcut menu. The Shape tab shows you a graphical representation of the 0+ '&`Q!u  
    spherical bump shape that is the bottom of the light guide. !qg`/y9  
    You might be curious as to why you cannot see the 3D texture property zones you vr l-$ii  
    defined. They are invisible by default, because drawing thousands of texture 7]bGc \  
    elements can make displaying and exploring the model somewhat slow. If you ^ytrK Q  
    choose to make them visible, 3D textures are displayed in wireframe, even if the +sA2WK]

    of the BEFs (brightness-enhancing films) built automatically by the utility.

    1 是autolisp 不是autolist GTd,n=  
    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 rILYI;'o  
    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 g- gV2$I  
    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 02^rV*re  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 4r}51 N\  
    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
