lightscape dos 下渲染
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)
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.

a.建模时给物件起名/分配颜色(cad的颜色)/并把材料相同的物件attach到一起
b.在3d max里建模用cad的颜色转到lightscape时会自动按照颜色生成layer...
.用插件在3d max里可以直接生成.lp插件是免费的
.有不少人模型从rhino里导到3d mxa理会发现"少面"或从cad里无论用.3ds还是.dxf，那是法线的问题,统一下法线就行了!
3.lightscape从头加速!!!
a.display--autoreraw 去掉"√"可在需要时按f5刷新;
view--set viewport size:user defined640*480(建议15"显示器的朋友使用)
b.open--.lp
file--properties--display interactivity
max.display texture64*64(32*32)低显示不会影响你输出图像时的精细度...
file--properties--colors
background h:210 s:0.2 v:0.9(淡蓝就行)与加速无关但与alpha通道有关
c.layers--rmb(右建)--all off
选中要处理的模型,双击(或rmb on)
lmb单击窗体,按下f5
select(shift+1) surface (shift+f)
select all(这时只选显示的层内所有模型的面)
红色线框"罩住"后--rmb--surface--processing
√occludin 使闭塞/√receivin接受/√reflection反射(去掉反射:好处自己想去...)
mesh coarse 1--0.5(降低细小的面的处理质量.)
deselect all--layers--rmb--all on--f5
d.lvs--windows图形窗口下渲染注意:
/按下为开启
/__double buffer -双倍缓冲
/__culling -去掉背面(这里有不少人还有我的同学误解,不是去掉背对你的面背对canera的面而是法线反的面...!!!)
/__blending -混合(texture--blend用到才起作用)
/__antialiasing -抗锯齿
/__ambient -环境光检验(不建议开启)
/__txtures -显示纹理
/__enhanced -增强显示(不建议开启!你可以用简单模型看看...)
/
/wireframe比solid快1.4--2倍(还是得看你现存)
e.lvs--dos渲染:
/命令已经讲过了...这里只告诉常有够用的命令和使用方法(windows下--开始--程序--ms-dos方式)
/__lsrad -求解- cd.. cd progra~1 cd lvs32 cd bin (自己找到自己安装lvs32的地方)
__\lsrad -v -cp 50 f:\templvs\temp01.lp(.ls)
/__lsray -出图- cd.. cd progra~1 cd lvs32 cd bin (自己找到自己安装lvs32的地方)
__\lsray -x 640 -y 480 -aa 3 -v (-alpha) (-w) (-sh) f:\templvs\temp01.ls f:\templvs\temp01.tga
