这是核心的旋转公式，
左键拖动，右键旋转，滑轮当然是缩放咯！！嘎嘎~~ 自己先占了5楼

我觉得你可以写一个跟DirectX或者OpnGL一样的3D引擎出来

厉害

是不是需要高深的数学知识？

效果很棒，高手啊。

进军二阶魔方旋转动画
以前做的无动画的模拟图

三维坐标怎么转平面坐标

我发现我在跟你做一样的东西

这是tc运行的吗？

请教一下楼主，就简单的正方体而言，你是如何规划它侧面线条的长度和角度的，

请教一下楼主，
pt_3d(pt_3d *pt)
{
this->x=pt->x;
this->y=pt->y;
this->z=pt->z;
}
作为新手，看不懂是怎样回事
还有cent x，cent y 的含义
