| dos下渲染会比在win图形界面上用线框显示渲染快大约1.5倍(线框显示是实体显示渲染的2倍左右)  前面的数据我感觉不大准确,在我实际做图时感觉大约只能快三分之一左右不过怎么说也是快了呀:) 
 首先你要有一个.lp或是.ls的文件.然后用LSRAD.EXE来进行求解LSRAY.EXE来输出图像.

 LSRAD 的所有命令:
 
 Copyright (C) 1991-1999 Autodesk, Inc.
 usage: C:\PROGRA~1\LIGHTS~1\BIN\LSRAD.EXE [options] file
 options:
 -ac allow attribute and light source changes
 -nac don't allow attribute/light changes (more efficient)
 -cp n save output file every n iterations (default=no check pointing)
 -cpt n save output file every n minutes (default=no check pointing)
 -df file alternate default file
 -do process direct light sources only
 -h print this message
 -i interactively confirm existing files overwrite
 -lf file layer library file
 -nopm do not preserve mesh of existing solution
 -o file alternate output file name
 -pm preserve mesh of existing solution
 -q print extra file information as files are loaded
 -r reset existing solution prior to processing

 -v show status messages
 file input ".ls" or ".lp" file
 
 -------------------------------------------------------------------------
 
 -ac 允许光源和属性的改变,缺省依文件内的设置

 -df file 读入指定的参数文件
 -do 只进行直接光照
 -h 显示帮助信息
 -i 传递结束后要求确认覆盖源文件,缺省是覆盖
 -lf file 读入指定的层状态文件
 -nopm do not preserve mesh of existing solution
 -o file 指定传递后的存盘文件
 -pm preserve mesh of existing solution
 -q print extra file information as files are loaded
 -r 传递前清除以前的文件,从头开始
 -sh [all|direct|none] 计算所有阴影(缺省)|计算直接光照阴影|不计算阴影
 -term n 计算n步后输出结果,缺省无限计算
 -termp p 计算到传递p%后,输出结果
 -termt n 计算到n分钟后输出结果
 -v 显示每一步的结果
