想問三維軟件內 "UV"的全名是乜?

想問三維軟件內 UV coordinates
U 全名是什麼?
V 全名又是什麼?
我明白U, V , N ( normal) 系surface 上 topology 既coordinate

但想知 U V 有無一個全名 ..或 其實沒有名的 (like xyz)

謝

U and V are axes on a plane, similar to XYZ are axes of 3d space, not full name for them.

U & V 系形容 texture coordinate 既 latitude & longitude, 又等於 X & Y.

當時決定叫 UV, 系因為 latitude & longitude 個名難記, XY 又已經用系 3D coordinate system. 所以用 horizontal 及 vertical 黎分, HV 當然唔好聽, 咪叫 UV 囉

UV----->Ultraviolet

UV mapping is a 3D modelling process of making a 2D map representing a 3D model. This map is associated with an image known as a texture. In contrast to "X", "Y" and "Z", which are the coordinates for the original 3D object in the modelling space, "U" and "V" are the coordinates of this transformed map of the surface. Then the image is back-transformed ("wrapped") onto the surface of the 3D object. For example, it is used to give an animated character a realistic looking face, but various other applications are possible.
