Video mapping is a modern technique born from the convergence of art and technology, so its use has a place in the artistic world and the commercial world more linked to technology.
In Dallas projection mapping is the art of using video and light projections on any surface, turning everyday objects into dynamic three-dimensional scenarios with really stunning effects that produce an immersion in the audience since the object’s surface is replaced by the one desired.
This technique is widely used in buildings such as cathedrals to create impressive video mapping scenes. But it is also used in small targets with advertising motifs.
Video mapping changes the appearance of the object in real-time by adding new dimensions and optical illusions. To do this, Dallas projection mapping professionals create movements in the thing they have previously made through specialized software for this type of use to project it later on that surface.
Making a Dallas projection mapping is not an easy task since many factors must be taken into account, such as the size, the shape of the projection, the distance at which the projection will be made if it will be outdoors, the type of lighting that will be found, the position at which the public will be found, the number of objects that must be animated. In short, it is a very complicated process.
The three fundamental elements that must be taken into account when doing video mapping are:
The light: it is what allows to project different colors and forms on the surface. Through light or the absence of it, volumes can be created, and by providing different tones, awe-inspiring illusions can be made.
The perspective: as critical as the light is the perspective; the project will be a failure if we do not take it into account. Placing the project from a certain angle and considering where the viewer will be positioned creates those 3D sets that attract so much attention.
The sound: supporting the visual show with the sound is essential for the impact and attraction is more lavish. For example, if a mapping is done on a cathedral and the animation created collapses, the image must be supported with the visual, offering a greater sense of reality.
How is the process?
As already explained, video mapping consists of projecting a video animation on a surface in three dimensions. To do this, custom images must be created for that surface, taking into account their forms, structure, etc. Therefore, that work will not be useful on any other body or object.
Map the object. In this first step, the item’s structure in which the projection will occur is obtained, whether it is a cube or a cathedral.
Make modeling. Once you have the object’s structure, you must carry out its reconstruction in a 3D design program.
Generation of the images. The images are created with video mapping software so that the object “comes to life,” changing aspects such as color, suffering some distortion, or any series of visual effects. Go and click on SEACAD.
The mapping in buildings or architectural mapping is one of the best-known uses of this technique, and spectacular results are obtained. It is common to see this technique in anniversaries about historical events in which these projections are projected on the cathedral or an emblematic building of the city. This makes the building question the illusion that it is on fire or collapsing, causing the astonishment of every person who sees it.
On the other hand, certain brands use advertising mapping to publicize their new products or lines. It is an advertising technique that is not very widespread, but that is becoming more fashionable. It was not used in small businesses until recently, but technology opportunities have allowed the emergence of micro mapping, mapping in small objects making this technique a little more economical.
