我以前也遇過同樣的問題,igs導入的圖形,對於source1類型的光源就是不能得到正確的結果,不只是lighttools,ASAP等軟件也是一樣.(猜測可能由於不同軟體間MESH的方法不一致導致)建議你不要使用導入的模型或儘量少使用導入的圖形.一定要導入的話,建議使用RHINO編輯,再導入,這樣效果也許會好一些.<br /> <br /> <br /> <br /> <br /> </div> <div class="postmsg">你可能需要修复一下你的模型,看有没有错误.通常有错误的面,在使用RENDER模式时会有粉红色出现.另可能对你的几个面要合成一个实体才可以正常追迹.因为LIGHTTOOLS是基于实体的,不是基于面的.你看你的锯齿处的光线并没有折射.</div> <div class="postmsg"><br /> <br /> 感谢两位的解答，再请教一下<br /> (1).PROE存成IGES文件时有多个选择项目，应该选择哪一个项目？(似乎只有存成「surface」形式的IGES檔才能由Lighttools读取，其它像「solid」、「shell」等内容的IGES檔似乎无法成功读入Lighttools)<br /> (2).下图中，由「surface」形式的IGES檔读入之后的情形如下图，各面各自独立，这样正确吗？可修正？<br /> (3).将「各面」的材质设定为PMMA后，进行raytrace，光线在前侧面会产生衍射，后侧面则不会？？？WHY？<br /> E:\temp\1.gif<br /> <div align="right"><font color="#000066">[此贴子已经被作者于2005-12-17 10:08:49编辑过]</font></div><br /> <br /> <br /> <br />

TRACEPRO中也有此工具.不过TRACEPRO中方便一些. 你自己研究一下吧.最好的格式是SAT(ACIS)格式.比较通用.多看看帮助,可以解决你的问题. <br /> 下面的附件可以参考:<br /> <br /> </blockquote></div><br /> <br /> 否认您的观点,应该是lighttools比较合适也比较好. 其它的同意</div> <div class="postmsg">LT 没有PRO/E的转档工具,而TP有的.很方便.</div> <div class="postmsg">1.TP 支持wildfire 2.0版本？<br /> 2.TRACEPRO中REPAIR按钮在哪？</div> <div class="postmsg"><<img src="static/image/smiley/default/titter.gif" smilieid="9" border="0" alt="" />>你做的是不是fresnel lens啊？还是整形元件？</P></div> <div style="height200px;"></div> <ul class="xl xl2 cl" style="border-top: 1px #cccccc dashed;margin:5px 0 ;padding-top:5px"> <dl><b> 同一主题资料:</b></dl> <dl style="margin:10px 1px;display:inline"><a href="attachcenter-page.html?aid=6710" title="3alM9vUk.gif"><img src="data/attachment/forum/dvbbs/2005-6/200561522222415668.gif" alt="3alM9vUk.gif" title="3alM9vUk.gif" onload="javascript:if(this.width>130)this.width=130;"></a></dl> <dl class='icon'><img src="static/image/filetype/pdf.gif" border="0" class="vm" alt="" /> <a href="attachcenter-page.html?aid=6726" title="vR3P0L7K.pdf">vR3P0L7K.pdf</a> <font color="#AAAAAA">(60.89 KB)</font> </dl> </div> </div> </div> </div></div> </div> <!--autocomment filter by maxnum--> <div class="ft_wp"> <div id="ft" class=" cl"> <div id="flk" > <p> <a href="http://wpa.qq.com/msgrd?V=3&Uin=20600600&Site=光电工程师社区&Menu=yes&from=discuz" target="_blank" title="QQ"><img src="static/image/common/site_qq.jpg" alt="QQ" /></a><span class="pipe">|</span><a href="http://m.oecr.com" >手机版</a><span class="pipe">|</span><a href="http://so.oecr.com" title="站内搜索" target="_blank" >搜索</a><span class="pipe">|</span><a href="http://www.focaloptics.com" title="主办单位：武汉焦点光学技术有限公司" target="_blank" >焦点光学</a><span class="pipe">|</span><a href="http://www.oecr.com" target="_blank">光电工程师社区</a> ( <a href="http://beian.miit.gov.cn/" target="_blank">鄂ICP备17021725号-1</a> <a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821" target="_blank">鄂网安备42011102000821号</a> ) <span id="tcss"></span><script type="text/javascript" src="http://tcss.qq.com/ping.js?v=1eOg" charset="utf-8"></script><script type="text/javascript" reload="1">pgvMain({"discuzParams":{"r2":"1028778","ui":0,"rt":"plugin","pn":1,"qq":"000"},"extraParams":""});</script></p> <p class="xs0"> <span id="debuginfo"> Copyright 2015 光电工程师社区 版权所有 All Rights Reserved. </span> </p> </div> <div id="ftl" > <p>申明：本站为非盈利性公益个人网站，已关闭注册功能，本站所有内容均为网络收集整理，不代表本站立场。如您对某些内容有质疑或不快，请及时联系我们处理！ </p> </div> <div id="frt" > <div class="wp"> <p class="dd01"> © 2001-2022 <a href="http://www.oecr.com" target="_blank">光电工程师社区</a> 网站备案号：<a href="https://beian.miit.gov.cn/">鄂ICP备17021725号</a> 网站公安备案号：<a href="http://www.beian.gov.cn/portal/registerSystemInfo?recordcode=42011102000821">鄂42011102000821号</a> Powered by <a href="http://www.discuz.net" target="_blank">Discuz!</a> <em>X3.2</em> </p><p class="dd02">GMT+8, 2025-12-19 04:31 </p> </div> </div></div> </div> </div> <!--bottombg结束--> <script src="home.php?mod=misc&ac=sendmail&rand=1766089886" type="text/javascript"></script> <!--<div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> --> <div id="scrolltop"> <span hidefocus="true"><a title="返回顶部" onclick="window.scrollTo('0','0')" class="scrolltopa" ><b>返回顶部</b></a></span> </div> <script type="text/javascript">_attachEvent(window, 'scroll', function () { showTopLink(); });checkBlind();</script> <div id="discuz_tips" style="display:none;"></div> <script type="text/javascript"> var tipsinfo = '1028778|X3.2|0.6||0||0|7|1766089886|6f705cf35ddb611d0e15d4512f44acd2|2'; </script> <script src="http://discuz.gtimg.cn/cloud/scripts/discuz_tips.js?v=1" type="text/javascript" charset="UTF-8"></script></body></html>
