Magnificently illustrated art instruction manual ranges from classical to contemporary eras. Black-and-white photos, drawings, and reproductions of paintings by Old Masters complement chapters on drapery studies, anatomy of dress, standard poses, other topics.
Did you know that any straight-line drawing on paper can be folded so that the complete drawing can be cut out with one straight scissors cut? That there is a planar linkage that can trace out any algebraic curve, or even 'sign your name'? Or that a 'Latin cross' unfolding of a cube can be refolded to 23 different convex polyhedra? Over the past decade, there has been a surge of interest in such problems, with applications ranging from robotics to protein folding. With an emphasis on algorithmic or computational aspects, this treatment gives hundreds of results and over 60 unsolved 'open problems' to inspire further research. The authors cover one-dimensional (1D) objects (linkages), 2D objects (paper), and 3D objects (polyhedra). Aimed at advanced undergraduate and graduate students in mathematics or computer science, this lavishly illustrated book will fascinate a broad audience, from school students to researchers.
One of the foremost drawing teachers shows how to render seven different kinds of folds: pipe, zigzag, spiral, half-lock, diaper pattern, drop, and inert. 200 black-and-white illustrations.
Autodesk Inventor was introduced in 1999 as an ambitious 3D parametric modeler based not on the familiar AutoCAD programming architecture but instead on a separate foundation that would provide the room needed to grow into the fully featured modeler it now is almost a decade later. Inventor 2009 marks a change of focus in the development of Inventor from an up-and-coming application to the current release with the inclusion of the design accelerator wizards and with refined core functions. The maturity of the Inventor tools happily coincides with the advancement of the CAD market’s adoption of 3D parametric modelers as a primary design tool. And although it is important to understand that 2D CAD will likely never completely disappear from the majority of manufacturing design departments, 3D design will increasingly become a requirement for most. With this in mind, we have set out to fill the following pages with detailed information on the specifics of the tools, while addressing the principles of sound parametric design techniques.
