    小弟是新手,请问相对于ASAP,在设计导光板方面,LT有什么优和缺,能比较下吗???谢了

    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. km<~H w>Z  
    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 M!jW=^\  
    The Backlight Utility was helpful to build the backlight system quickly. However, jI V? p  
    the bumps must be parameterized in order to get the desired output distribution. pnG8c<  
    You can do this easily using the LightTools Properties dialog box. y;>I'e  
    1.In the System Navigator, expand the items LightGuide, CubePrimitive_1, S BoF (0<  
    BottomSurface, and Zones. Then, select Texture, as shown in the following \9?<E[  
    figure. GJuD :  
    2.Right-click and select Properties on the shortcut menu. @ixX?N)V  
    3.Select the Geometry tab. ).boe& .  
    4.Select the arrow next to the Placement drop-down list, and select Bezier. Click KN`z68c4L

    The default number of bumps is 100 (10 X 10). You need to change these Iz8 ^? >X  
    parameters to match your design. Note that LightTools allows many other 7EO&:b]  
    placement options, but you will use the Bezier placement option for this Cr%r<*s  
    example. U:|v(U$"?  
    5.On both the X Placement tab and Y Placement tab, change the Number of bLzuaNa'  
    Bumps parameter to 300, as shown in the following figure. Click Apply after #G=QL(f>/  
    each change. 6V?RES;X  
    6.Click OK to close the dialog box. 7jbm w<d)9  
    Note that the number of bumps is 300 X 300, which results in about 90,000 1c"m$)a4  
    bumps on the surface (~ 5143 bumps/in2). These bumps are arranged in a h3IkOh4|h  
    manner defined by the Bezier parameterization option. Please see Chapter 5 of eM"mP&TTL  
    the LightTools Core Module User’s Guide for more information. With the pi}H.iF  
    current parameter values, the Bezier option varies the bump spacing along the 1Qu,]i`  
    length of the light guide. The spacing in the orthogonal direction is constant. UhTr<(@  
    The X and Y refer to the local coordinate system of the surface. `6$b1qv,

    Using the methods described in previous chapters, you may want to check your EI.Pk>ZIm  
    model before you run a simulation. ^ks^9*'|j

    1.In the System Navigator, click to open BottomSurface of the LightGuide, then #jx?uS  
    click Zones, and then click Texture. DOIWhd5:  
    2.Select SphericalElement, and then right-click and select Properties from the Lp)8SmN  
    shortcut menu. The Shape tab shows you a graphical representation of the y;Ln ao7i  
    spherical bump shape that is the bottom of the light guide. XL=R]IC<.  
    You might be curious as to why you cannot see the 3D texture property zones you cgeS)C7  
    defined. They are invisible by default, because drawing thousands of texture walRqlo@  
    elements can make displaying and exploring the model somewhat slow. If you R<-C>D  
    choose to make them visible, 3D textures are displayed in wireframe, even if the :+Ax3  
    display mode is set to translucent. Wireframe rendering displays a bit faster and _5w?v~65

    1 是autolisp 不是autolist m_"p$m;  
    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 1uS-Tx  
    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 zL},`:(.  
    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 /3[ 9{r  
    贴上你在cad中读出的数据就好了。半径的参数一样办理 M 1^C8cz  
    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
