Short definition
Projection mapping (also video mapping) is the technique of precisely projecting video content onto irregular three-dimensional surfaces — from building facades to vehicles and complex stage structures.
Detailed explanation
In projection mapping, the image is digitally warped and adjusted to fit the exact geometry of the surface. This process — called warping and masking — runs through media server software that links a 3D model of the surface with the video content. The result is animation that appears three-dimensional, visually transforming the physical shape of the object.
Mapping requires precise calibration between projector and surface. Larger installations use multiple projectors with edge blending; laser projectors are preferred for their brightness and pixel sharpness. Outdoor projections commonly need 20,000 to 50,000 lumens per projector. Preparation requires accurate 3D scanning of the surface plus intensive creative and testing phases.
Relevance in this field
Projection mapping is one of the most spectacular tools in high-end event production. It creates unique, memorable visual experiences but is also one of the most technically demanding disciplines in the industry.
Practical example
A car manufacturer unveils a new model using projection mapping: four laser projectors illuminate the body, hood, and rear of the vehicle on a turntable. A media server plays animations that transform the surface into shifting sand, water, and light.
