Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique [1] [2] used to turn objects, often irregularly shaped, into display surfaces for video projection. The objects may be complex industrial landscapes, such as buildings, small indoor objects, or theatrical stages.
Obscura specializes in custom video content, large scale interactive displays, architectural installations, kinetic sculpture, stage shows, and projection mapping that turns nearly any surface into a video screen. [3] Obscura Digital projected of images of endangered species on the Empire State Building for the film "Racing Extinction", 2015.
A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.
Figure 2 The Projection Augmented model concept. A projection augmented model (PA model) consists of a physical three-dimensional model, onto which a computer image is projected to create a realistic looking object (Figure 2). Importantly, the physical model is the same geometric shape as the object that the PA model depicts.
Projective texture mapping is a method of texture mapping that allows a textured image to be projected onto a scene as if by a slide projector. Projective texture mapping is useful in a variety of lighting techniques and it is the starting point for shadow mapping .
The lines connecting these points are commonly referred to as projectors. The centre of projection can be thought of as the location of the observer, while the plane of projection is the surface on which the two dimensional projected image of the scene is recorded or from which it is viewed (e.g., photographic negative, photographic print ...
