what does the U stand for in UV mapping?
Hi there,
I looked through the manuals and through Inside Lightwave, but haven't been able to figure that out. "V" I guess stands for Vertex. thanks |

I may be wrong, but I think it doesn't stand for anything.
XYZ are cardinal directions, so they wanted to do the same with texture space. The powers-that-be dubbed those directions UVW to not confuse the two. That's what I think, anyway. So, UVs could have very well been called ABs if they decided to go the other way.

Mike,
did a good job to confuse me though ;-) I was guessing UltraViolet, UpperVertex, UltraVoxel ... I love abreviations ... thanks |

Mike is entirely correct. They're just another set of axes in 3D space...

not entirely precise though;
XYZ is your world coordintae system, while UVW is a transformed coordinate system (also used in maths), in this case it's your "tangent space" coordinate system, transformed in a way that U and V actually make up the surface of your object so W would be your surface normals.
