Maya .ma 矩阵比例转换
这也许是一个有点偏离主题的话题，但 Maya 在特定尺度的平移矩阵变换上给了我严重的悲伤，而且我无处可去。
在 Maya 决定添加 .spt 属性（通常为 setAttr ".spt" -type "double3" 1 2 3 ;）之前，我的 Maya .ma (Maya ASCII) 导入器一切正常。 从这个有点模糊的文档我得出了结论三个 .spt 值进入比例转换矩阵。
我非常非常感谢您就如何在矩阵转换中处理 .spt 提供的任何指示！
A perhaps slightly off-topic subject, but Maya is giving me serious grief on a specific scale translation matrix transformation, and I have nowhere else to turn.
Everything works fine with my Maya .ma (Maya ASCII) importer until Maya descides to add an .spt attribute (typically setAttr ".spt" -type "double3" 1 2 3 ;). From this somewhat vague documentation I came to the conclusion that the three .spt values go into the scale translate matrix.
I would very, very much appreciate any pointers you could give me on how to handle .spt in my matrix transformations!

我知道这是一个令人讨厌的黑客行为，但是您的导入程序可以添加反向转换来撤消 Maya 在导入时对您的内容所做的操作吗？
I know this is a nasty hack, but could your importer add in the reverse transformation to undo what Maya is doing to your stuff on import?
我太累了，无法正常思考，睡了几个小时后，我意识到问题不在于变换，而在于枢轴。 我设法猜测枢轴是如何构造的，即根据两个属性
.rp + .spt。达赖喇嘛对于睡眠的看法是正确的。 :)
I was too tired to think straight, and after some hours of sleep I realized that the problem lie not in the transforms, but in the pivot. I managed to guess how the pivot was constructed, namely from the two attributes
.rp + .spt.Dalai Lama is right about sleep. :)
