如图1在大球面上做花纹,花纹边界大小为9×6的,球面R为283
如图2是单个花纹造型,花纹是单一曲面,曲面四边由四个弧线控制,长向弧是R11 ,宽向是R5.
要求花纹造型尽量简单(利用阵列,拷贝等方法)<img src="attachments/dvbbs/20037514383342546.gif" 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/20037514383342546.gif\');}" onmousewheel="return imgzoom(this);" alt="" /><img src="attachments/dvbbs/20037514393440570.gif" 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/20037514393440570.gif\');}" onmousewheel="return imgzoom(this);" alt="" /> |
