![]() In 2D, U and V coordinates therefore replace the X, Y and Z from the 3D world, but correspondance with the 3D mesh remains. The process of preparation of the 3D object, to be made into a flat 2D representation is called UV mapping or UV layout. This image-representation is made according to the UV layout of the 3D object, and keeps compatiblity with the traditionnal 2D texture workflow. This lowers the required computer ressources and allows for a more fluid real-time painting experience.Įven in modern 3D texturing software that display the textured object directly in 3D, a 2D image-representation of the 3D object is made to save the work. The main advantage of this method is that is doesn't require the 3D model during texturing. This way, a 2D image manipulation software is used to create textures by painting directly over the corresponding UV parts. This process is required before texturing to preprepare 3D models for texturing, because painting is saved onto a flat surface. Instead of taking a flat roll of cloth and making it a human-shaped piece of garment, you cut the 3D object on its seams to make it flat again. It is similar to the opposite actions of gift-wrapping a present or making garments in real life. UV mapping is the process of wrapping a 3D object with a 2D image over its surface. ![]()
