Description
传统足球是由20块正六边形（白）和12块正五边形（黑），一共32块皮组成的。但是足球也在发展，在一些大的比赛上，会制定特定的足球以供比赛使用。2006年德国世界杯的用球“团队之星”采用了全新的异形拼块和无缝压合技术，史无前例地将足球球面拼块减少到14块，最大程度地消除了球体表面不规则的凹凸，令球体呈现完美圆弧，从而有效提高了足球运行的精准度。2010年的南非世界杯，比赛用球“普天同庆”突破性地仅由8块表皮组成，阿迪达斯首次采用球形制模的方法使每1块表皮都实现2维立体结构，然后以热粘合技术拼接完成，从而使新球较以往更圆、运行更精准。随着技术的进一步提高，相信会有更优的足球出现。
