What is videomapping or projection mapping?

Video mapping or 3D lighting was first introduced in 2008. Today, the largest and most reliable commercial companies in the world use video marketing for environmental advertising and unveiling their products.

What is video mapping?

Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique used to transform objects, often irregularly shaped, into representational surfaces for video display. Objects may be complex industrial landscapes such as buildings, small interior objects or theater stages. Using specialized software, a 2D or 3D object is spatially mapped onto a virtual program that mimics the real environment on which it is to be displayed. The software can then interact with a projector to project any desired image onto the surface of that object. This technique is used by artists and advertisers who can add dimensions, optical illusions, and motion concepts onto previously static objects. The video is usually combined with audio. In recent years this technique has been widely used in the field of cultural heritage, as it has proven to be an excellent educational tool.

Video mapping equipment

To build the equipment and perform 3D video mapping, first the desired location and surface are identified in terms of dimensions and structure, and in the next step, a 3D film is produced based on the size of the execution surface, in other words, a 3D plan on the selected frame of the mask. And the image becomes.

Therefore, in 3D mapping, the coordinates of the points are needed to define the object on the projector. Video dump from two components:

1. hardware
2. software

It is formed and like projection mapping, it gives you the ability to view Full HD images in 3D without 3D glasses. In this technique, since a different space is created for the audience in terms of sound and image, its sensory effect is greater.

What is projection mapping?

Video mapping or projection mapping is the visualization and display of movies and animations in 3D on all surfaces. This device will give you the ability to see in 3D without 3D glasses in all levels of Full HD image. To put it more simply, what is video mapping? We must answer:

Video mapping is the display of images on non-flat and colored volumes. In fact, in video mapping, instead of the image being displayed on a flat surface, it is displayed on objects and volumes. Video mapping is referred to by different names such as video mapping, projection mapping, projector mapping, projection mapping, etc., but its scientific and academic name is spatial augmented reality.

These surfaces can be complex industrial surfaces, show decorations or facades of buildings. In this technique, virtual 2D or 3D images are placed on these surfaces by software and hardware, and the software with projector control can coordinate and play the images with high precision with the volume levels.

The projector mapping technique is used by artists to create depth and light/movement illusions to attract the audience or to introduce a specific brand or its products. The characteristic of this technique is that it is specifically designed and planned for a specific building surface, and 3D images are created with a specific plot and coordinated with light, sound, and music in a short period of time to produce a work of art. leads

Its sensory effect is also greater because with this technique, a different space is created for the audience in terms of audio and visual, and therefore in its foreign examples that have been performed so far in Germany and England, more emphasis is placed on music and the experience of this The technique is important for valuable topics such as the Islamic Revolution and terror martyrs and can be the beginning of more serious work.

Payarsa Electronics Company implements video mapping throughout the country, including video mapping in Hamedan, Isfahan, Tehran, Qazvin, Karaj, Shiraz, Hamedan, Tabriz and Mashhad municipalities.

What is the application of 3D lighting?

Video mapping can be used in:

Concert
the hall
the conference
Seminar
Hypermarket
Restaurant
Meson
Clothing boutiques
gallery
Bank
residence
Building facades
The interior of the building

And …. Today, among the various methods that exist for urban lighting; Videoamping (3D lighting) is the newest type of lighting, which is mostly used in ceremonial programs and holidays on a temporary basis.

By using 3D lighting, you can create a desired volume for any space.

By using this tool, you can turn historical monuments and architectural works into the focus of attention and instill a special meaning to the viewer.

Video mapping methods

To create and implement videomapping, first the desired location and surface are identified in terms of dimensions and structure, then a 3D film is prepared according to the size of the execution surface; in other words, the 3D plan is depicted on the selected frame. In 3D lighting, the coordinates of the points are needed to define the object on the projector.
