scaling and offset

Dear all,

I often come across the term scaling and offset in texture mapping. What does scaling and offset refer to.

With regards

It could refer to many things.
It can be one-time operation in modelling software, it can be an attribute added to object’s description (to be applied when loading or rendering that object). Finally it can also be something done in realtime, based on some formulas.

Generally, texture coordinates are no different than vertex coordinates - they are transformed before being used in rendering or they can be transformed during modelling process in modelling software.
