Need some information about projection mapping? Here is what you need to know

What is projection mapping?

If you want to turn irregular shape objects into a display surface for video projection then a technique is used called projection mapping. You can find it quite similar to video mapping.

Projection Mapping

What are these objects?

You can find these objects.
  • Buildings
  • Tiny indoor objects
  • Theatrical stages

These are all industrial landscapes.

How is mapping done?

Basically, the corners of the video are mapped by specific software into the surface once the projected object is chosen or created. Follow the following steps:
  1. Images and videos must be selected for projection.
  2. Select a designated surface to place each and every video on it.
  3. This can allow the other person to automatically map the complete scene in 3d. This can help the person project and mask the image back in the framework.
  4. The game of masking begins to know. In this step, different elements of the building are actually masked by their exact shapes and positions using opacity templates. The space of projection also counts.

A peek into 3d mapping

The relation between objects and projector holds importance. The position and specification of lengths plus the XYZ orientation of the projector also connect with the object. The determination of a virtual scene must be the outcome of the web of relations. The tool that can be used to gain this end is BLAM.

3D Projection Mapping

Size of projectors

If the projections are used on a large scale then the size of the projects must be 20000 lumens of more. For example, city skyscrapers. Smaller projectors having less output can work for small productions.

What are some projection mapping software?

Following are some of the famous projection mapping software:
  • Mad mapper
  • Heavy M
  • Q-lab
  • Troixatronix’s
  • Isadora
  • Facadesignage
  • Arkaos media master
  • Grand VJ
  • VPT 6.0

What are the download options?


A creative artist can download all the above mention software for using them in projects through the following packages:
  • Adobe photoshop
  • Adobe after effects
  • Blender
  • BLAM

Categories of project mapping

There are four segments into which project mapping can be separated:
  • Video jockeying

Projections are used to augment live events. Per-program videos and a blend of different effects are displayed in a complete dynamic mode.
  • Theatrical
There is a conjunction of the dance of on-stage performance with the cued scenes on-demand on which projections are pre-set.
  • Static or interactive
Programming is used to create an interaction between the environment and the viewers. A display is a set-up to perform this function.
  • Video
A single fluid, non-interactive video is crafted out of a long segmented show that is played from the start to the end.

Projection Mapping Technology


Uses of project mapping


  1. Scenes are often projected on the sides of the building by advertising campaign visa mapping techniques.
  2. In a theme that is based completely on experience immerses audience members at conferences where projection mapping is used as a means of decoration.
  3. 360 degree projections are being attempted to make for a vast exposure. It means technology like domes is using projection mapping and combining it with virtual and augmented reality to achieve their goal.
  4. TV and films are also using this technique for creating an environment that is immersive.

What is the cost of projection mapping?

Based on 1 minute of 3d video content the average projection mapping costs about 10,000$.the cost of projectors, media servers, and hard drives are not part of this amount.

Types of projection mapping

There are 3 common types of projection mapping

  • Cylindrical map projections
They basically portray are earth. Horizontal parallels align with coordinate lines and cross the meridians at right angles. There is equal space between al meridians.
  • Conic map projections
The angular distance between meridians is dictated by their maps. They cover the top of the globe. They are best in use for regional and hemispheric maps.
  •  Azimuthal map projection

They consist of some angular relationships which are also known as great circle arks or geodesic art. Straight meridian lines emerge from center making a circle. This is their basic characteristic.
