There is truly no limitation to where you can use projection mapping. You can use small projectors to cover small objects in everyday spaces like retail shops, restaurants, museums and other places where you want to add a layer of interactivity and entertainment. You can use large professional-grade projectors to project on larger objects like cars and buildings. Depending on the size of the object and the setup space available, you can calculate the kind of projectors and software tools you will need to create an experience.

A very basic understanding of the concept is that projection mapping is the art of recreating physical objects into a digital format, like a 3D model or a 2D flat map. This model or map is then used as the base layer to create digital content, the content can have 3D effects with depth or be more 2D flat like video content. The digital video is carefully created to make sure the position of the content and the position of the projectors placed on site is aligned.

The rendered content is then taken onto the site, fed to projectors and mapped back onto the physical real-world object. This technique of mapping the digital content onto a physical structure gives the viewer an optical illusion, termed 3D projection mapping. The content can be real-time graphics, videos or other digital content or it can be pre-rendered videos that are played back.

Many more complicated and highly detailed projection mapping setups, use accurate 3D UV maps to re-calibrate the content onto the physical surface. With advances in technology, you can even use a LiDAR camera to re-create real-time 3D projection mapping shows.
