三维矢量显示
如果给定一个模为1的三维矢量,把他显示在球面上的一个点,也就是在一个透视球体上取点,怎样做这个球体并描点<img src="attachments/dvbbs/2006-6/200661610235074699.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/2006-6/200661610235074699.jpg\');}" onmousewheel="return imgzoom(this);" alt="" /> <P>我每次问的问题,都没人能回答。<BR>刚才思考了半天,考虑用3D Graph控件还是Canvas还是直接用Picture控件<BR>第一种的话要能够在空间描绘出来一个球体,这个算法我还不知道<BR>第二中和第三种都要自己写平面模拟3D的算法。</P><P>初步是这么考虑的,高手看到请指点。</P> 来个高手帮帮忙
