Projection Mapping

After visiting the spaces, especially the royal exchange theatre, the idea of using lights to project an image either on to a wall or onto boxes, is one I have been looking into. The technique is called projection mapping.

Projection mapping, also known as video mapping and spatial augmented reality, is a projection technology 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.[1] 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.

The above two videos show very complex versions of projection mapping, and are nowhere near what I would be able, or want to achieve.
Using online tutorials such as the following ones, I set about attempting my own version of this technique


After connecting my laptop up to a projector, I opened a drawing app, which I could use full screen, in this case I used Sketchbook Pro. I projected my laptop screen on to a wall in my house. and then using the pencil tool, and shift clicking to ensure I had straight lines drew a rough representation of the wall area, putting lines where, the geometry of the wall changed.

Whilst I really want to continue with this as a project, I think it may be to ambitious for the time frame we have, as well as to find a suitable space would be challenging.
