Flexible Projection

This work began as an exploration of the effects of allowing light to bend within a projection. As we created a framework for parametrically controlling these bent viewing volumes we found this framework to be useful for a variety of nonlinear and linear projections.

The following images demonstrate one of the more radical projections created with our framework.

In 2009 we extended this work, relating how and when nonlinear projections are used by artists as well as review current nonlinear projection techniques used in computer graphics. Additionally we describe the use of Flexible Projection in the collaborative creation of an art installation. For more information please refer to the following publication:
