Video Mapping: what it is and the simplest way to do it!

Video mapping - article cover

It is now common to see architectural constructions and landmarks blazing through the night in big and small cities. Enthusiasts and curiouses alike wander around, and are awed by the wonderful visual miracles. While strollers don’t know how to name these “illuminations”, they might not even be aware they’ve seen it before and on smaller structures. For aficionados, this wonderful piece of technology they’re witnessing is none other than projection mapping.

Outgrowing its function, video mapping is nowadays used to enhance artistic performance in concerts and theatre, provide an atmosphere for a product launch or yet animate a corporate event. And with mapping solutions flourishing, the path to delivering immersive experiences has never been clearer. But then, some questions need first be answered: what is projection mapping? What are its specificities? How do you do video mapping? Is there any training to learn video mapping? We provide all of the answers in this article.

What is video mapping?

First things first, let’s define what video mapping is (also known as projection mapping). Projection mapping is a projection technique used to turn objects and elements into a display surface for video projection. This method appeared in the 2000’s and consists of projecting videos and visual animations by playing with their asperities thanks to one or more video projectors. 

The objective of mapping is to create optical illusions by putting visual content on static volumes.

The projection surface is the fundamental distinction between 2D and 3D projection mapping. 

While the nomenclature is not necessarily known from the public, examples that can be provided are self-explanatory

Indeed, monumental mapping – projection of videos on monuments – is the most well-known projection mapping form. It accounts for 3D elements and therefore uses 3D video mapping.

Projection mapping - building facade

2D mapping is usually done on flat or curved surfaces where the measurables are length and height. When working with objects and textured surfaces, 3D video mapping is used to account for depth and other spatial concerns.

So we know that any 2D and 3D physical element can become a projection surface. That means quite literally any object and anything.

Generally speaking, the three-dimensional factor brings more attention and interest to the creation. The more there is a dimensional interest, the more spectacular and relevant the projection mapping is. A 3D projection mapping intrinsically generates more value and takes on a true meaning.

Effectively, going from 2D to 3D provides an enhanced experience for the spectator.

As an example, here are some of the most exceptional 3D video mappings.

Video mapping, for which surface(s)?

So far we’ve stated the importance of differentiating 2D from 3D mapping. In the same regard, video mapping surfaces are infinitely varied. They range from the facade of a monument to an architectural detail, from a stage set to a small object or a simple wall… Geometric accessories are also an excellent option to easily obtain a strong visual impact. 

All elements of reality can be transformed and metamorphosed by this virtual technology. This technique goes further than light design thanks to softwares that allows creating trompe-l’oeil in motion, spectacular optical illusions and 360° projections!

Video mapping is the possibility of designing surprising graphic and visual environments that bring the public into an immersive atmosphere to live an experience of mutating reality… towards another reality!

Video mapping: who can do it?

Enormous Projects

We know video mapping can be applied to absolutely any physical element. Meaning anything from infinitely small to gigantely colossal. And for this latter part, the market is occupied by the AV big players. 

They create massive works by combining several high-performance projectors for a single project. The visual rendering is outstanding, and the financial expense is equally so.

AV big players are, in general, technical providers who supply the essential technology for great experiences. They collaborate with creative agencies to create the audiovisual material that will be shown.

The agency is responsible for generating 3D material that will match the building flawlessly and exclusively. The agency is provided blueprints, prototypes, or designs in any format so that they should work on them before the event. The content development process is critical, and it is sometimes offered as a service by AV companies.

Projection Mapping for any projects

On the other hand, video mapping softwares have democratized the discipline – once reserved for technical experts – by making it accessible to the widest possible audience. Video mapping is now available to events professionals and agencies, experienced artists and entertainment specialists.  

Here are some examples: 

This stone mine mapping is a real-time audiovisual performance during which music and image are created live underground.

In this 5-part journey, visuals are linked to the sound using audio and CV information, driving generative patches in TouchDesigner.

Creative technologist Data.Flaw created an exciting gamified experience. Indeed, he brought interactivity to another level by connecting a Playstation 5 controller to HeavyM 2 via OSC.

French music band Free for the Ladies used projection mapping in their set design when filming and the result is electrifying. Filling their instruments and faces with color waves thanks to the most user-friendly mapping software, music vibes are flowing through the screen.

How do you do video mapping?

The creation of a mapping requires a certain discipline and consists of several steps:

  1. Prepare your equipment: video mapping tools are few, you will need a computer, a video projector, a video projection surface, a cable to connect the computer to the video projector and a software: we recommend HeavyM.
  2. Identify the projection surface: this consists in choosing the projection surface: an object, an architectural element, a decoration or an accessory specially designed as a structure adapted to 3D projection mapping: the Olga kit. This triangular structure kit is a reference for the construction of 3D projection mapping sets. Easy to assemble, to hang and made of M1 fireproof material, it is perfect to create beautiful animations!
  3. Choose (a) video projector(s) and identify the appropriate positioning(s): the next step is to choose and position the video projector according to a distance calculation in relation to the projection surface to be covered. The power of the video projector is chosen according to the size of the projection surface (5,000 lumens for small projections and up to 20,000 lumens for monumental projections) and the ambient light level. The projector must be stable, at the right height and correctly focused to obtain an optimal rendering of the animations. After several adjustments, its placement must be definitive to avoid any risk of shift with the projection mapping to come. See our detailed article to help you choose your video projector.
  4. Develop a storyboard, model the projected surface, create motion design: certainly the most creative step, but also the most complex. This is the time to create animations that perfectly match the projection surfaces. These creations are usually made by motion designers and then exported as video files. The technicians in the field will then adapt these video creations to the projection surface using projection mapping softwares.
    To avoid complications, HeavyM offers simplified solutions for an intuitive and stress-free creative process. The software has built-in visual effects that can be combined without limit and it adapts all imported photos and videos, as well as content from other applications, directly to the projection surface. It’s a phenomenal time-saver!
