呵呵,按MVPR大大说的做做啦:
三草图扫描:
<img src="attachments/dvbbs/2004-2/20042138521615652.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/20042138521615652.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
第一个草图:
<img src="attachments/dvbbs/2004-2/2004213949585823.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/2004213949585823.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
第二个草图:
<img src="attachments/dvbbs/2004-2/20042139495655055.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/20042139495655055.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
第三个草图:
<img src="attachments/dvbbs/2004-2/20042139505185466.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/20042139505185466.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这里要注意:
草图里的弧是椭圆弧:
<img src="attachments/dvbbs/2004-2/2004213952972156.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/2004213952972156.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这一点和第一个草图添加一个穿透关系:
<img src="attachments/dvbbs/2004-2/20042139531587148.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/20042139531587148.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这一点和第二个草图添加一个穿透关系:
<img src="attachments/dvbbs/2004-2/2004213954268328.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2004-2/2004213954268328.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
另外:
1. 灯罩是曲面的话,只需将第三个草图中的两条水平线和中心的竖直线都改成构造线,然后改用曲面扫描即可。
2. 紧贴灯罩的外花可用成形到面的拉伸做出。
3. 挂钩也用扫描做出。
4. 36条小穗可以先扫描出一个,然后阵列。
其实做法也不限于我说的这些,总而言之,动动脑一定做的出来啦。[em21]
