lightform - Video Projection Mapping.

Lightform is a San Francisco, California. company developing AR hardware and software founded by Brett Jones, Raj Sodhi and Kevin Karsch in 2014

Lightform has two main products: the hardware, LF1, and the software, Lightform Creator. LF1 is a 3D scanner and media player that provides AR effects when it is paired with an image projector. LF1 performs this function by capturing the object that would be enhanced through AR application with its camera. After calibrating the image data according to the projector lens, the images are sent to the user’s laptop. Using the Lightform Creator, users can then apply AR effects based on their needs.

Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique[1][2] used to turn objects, often irregularly shaped, into a display surface for video projection. These objects may be complex industrial landscapes, such as buildings, small indoor objects or theatrical stages. By using specialized software, a two- or three-dimensional object is spatially mapped on the virtual program which mimics the real environment it is to be projected on. The software can interact with a projector to fit any desired image onto the surface of that object.[3] This technique is used by artists and advertisers alike who can add extra dimensions, optical illusions, and notions of movement onto previously static objects. The video is commonly combined with, or triggered by, audio to create an audio-visual narrative. In recent years this technique has also been widely used in the context of cultural heritage as it has proved to be an excellent edutainment[4] tool thanks to the combined use of a digital dramaturgy.
