J3d终于调试成功了，感觉java在UI设计方面，还是很复杂

鼓捣了半天，终于成功了，j3d是sun的官方扩充包，主要用于3d显示，调用的是本地库，所以速度算不上慢，但是编写起来也是有一定的复杂度的，如果有一个好一点的框架就好了，只能给爱好者玩玩了，java做企业web还是更靠点谱，不过我对企业什么的很没兴趣，而且还发现了一个IBM的IFRAME包，不是html里的<iframe></iframe>里的标签的意思，是一个基于swing的UI框架，可以设计出比较复杂的UI，效果还不错，透明框架什么的，还有不规则框架都可以做，不过也相当难写，这是我的亲身体会，额！

重新购买了域名和空间，希望别再和谐我的博客了，我一个悲剧程序员容易吗我，我真的什么也不知道，什么也不知道阿！
