Podcast #128: We chat with Kent C Dodds about why he loves React and discuss what life was like in the dark days before Git. Listen now.

UV mapping is the process of taking a three-dimensional mesh (X, Y and Z coordinates) and unwrapping it to a flat two-dimensional image (U and V coordinates), in order to texture the 3D model with 2D images.

U and V refer to texture-space coordinates, opposed to the usual X, Y and Z coordinates, which refer to 3D-space.
