Imagine you are drawing on a piece of paper with a pen. As you move the pen around, it creates a path or line. Now, imagine that you want to make sure that a particular point on that line stays in the same place even if you move the paper around. That's what a UV fixed point is.
In technical terms, UV refers to the two-dimensional map that specifies how a texture or image is applied to a 3D model. Fixed points are specific locations on that map that are marked in such a way that they stay in the same place even if the model is scaled or rotated. This is useful because it ensures that certain parts of the texture, like a logo or design, remain in the correct position and size on the model, even if the model is modified.
The concept of UV fixed points is important in computer graphics, where it allows for more precise and consistent texturing of 3D models. It may sound complicated, but it's essentially just a way of making sure that certain parts of a texture stay put, no matter what.
