Abstract:
Generally, interactive computer graphics are limited to a small subset of possible projections known as linear projections. To address this limitation we have created the flexible projection framework; a framework designed to model a wide variety of linear, nonlinear, and hand-tailored artistic projections in a way that is supported by computer graphics hardware. This framework introduces a unified geometry for all of these types of projections using a parametric viewing volume. Through this parametric representation we obtain the ability to create projections that make use of curved projection surfaces and curved projectors. Several applications will be discussed including panoramas, re-creating projections used by artists, and dynamic projections that change over time.
