真实世界坐标 [英] Real World Coordinates

问题描述

嗨

我怎样才能拥有骨架关节坐垫的真实世界坐标。我应该使用模型视图的反转和投影矩阵，还是有更简单的方法，比如函数来做:)？

How can I have real world coords of room from skeleton joints coords. Should i use inverse of model view and Projection matrix or is there an easier way like a function to do that :) ?

更清楚我想要变换骨架透视坐标到立方世界坐标。我相信它是透视投影的反转，所以我应该让我的模型视图和投影矩阵然后反转它们并乘以它们。是
这对吗？有没有更简单的方法呢？

To be more clear I want to transform skeleton perspective coordinates to cubic world coordinates. I believe it is the inverse of perspective projection so I should have my model view and projection Matrices then inverse them and multiply them. is this right? is there any easier way to do that?
