Buildings paper: Methods for Creating Curved Shell Structures From Sheet Materials

This paper describes some methods for producing developable surfaces with practical applications for creating useful lightweight, rigid, jig-less and elegant structural forms from sheet materials. Multiple related techniques based on the same fundamental principle can be used to generate a variety of interesting singly curved and doubly curved shapes. The system requires a minimum of specialist software, and is described in simple steps that can be followed by the reader with access to basic 3D CAD tools.

CAe paper - New methods to project panoramas for practical and aesthetic purposes

In this paper we propose the use of several geographic map projections to project a panorama into a flat surface, both for realistic purposes (where the projection can be easily accepted as a faithful representation of the original image) and for artistic purposes (where the projection is used as an artistic tool intended for the creation of an innovative interpretation of the panorama).
