UFUN和NXOPEN中的变换矩阵区别有哪些

这篇文章主要介绍UFUN和NXOPEN中的变换矩阵区别有哪些，文中介绍的非常详细，具有一定的参考价值，感兴趣的小伙伴们一定要看完！

UFUN中用于实体变换矩阵的函数为：
UF_MODL_transform_entities
NXOPEN中用于装配组件变换矩阵的类为：
ComponentNetwork
它们的变换矩阵方式是不同的，前者为动态变换，后者为静态变换。
动态变换求法：

            var invert = Current.Inverse();            var trans = invert.Multiply(position);

静态变换求法（先旋转后平移）：

            var cur = Current;            cur.Transpose();//转置            var pos = position;            pos.Transpose();//转置            var trans = cur.Inverse().Multiply(pos);            var rotation = trans.UpperLeft.ToMatrix3x3();            trans.Transpose();            var translation = trans.Translation.ToVector3d();

分享下我的两个移动相关的类（部分相关类没有提供）：
