Video Mapping Shows

It is a projection technique generally used to convert shaped surfaces into a screen surface for video projection.

Where is Video Mapping used?

These surfaces can be buildings, indoor objects, or complex industrial areas such as theater stages. Using special software, a two- or three-dimensional object is spatially mapped on a virtual program that mimics the real environment on which it will be projected. The software is mapped with a projector to fit any desired image onto the surface of the relevant object.

Who uses video mapping?

This technique is used by artists and advertisers who can add extra dimensions, optical illusions, and motion concepts to previously fixed objects. Video is often combined with or triggered by sound to create an audiovisual composition.

How is video mapping done?

After the surface to project is selected or created, special software is used to match the corners of the video with the surfaces. First, you need to select the images or video to project. Next, you need to place each video on its designated surface. Alternatively, you can choose to map the entire scene in 3D, and try to project and mask the image back into its frame. The next step is defined as “masking”, which means using it to truly “mask” the exact shapes and positions of the different elements of the building or projection area. In 3D Video mapping, defining the location of the object, XYZ direction of the projector, position, and lens specification should be determined. In order to achieve this goal, 3d design programs such as Blender, 3D Max, and similar are required. For large-scale projections such as city buildings and skyscrapers, large projectors with an output of 20,000 lumens or more are used. Large powered projectors are often combined to produce a single image, due to the full scale and brightness required for some large projects.
