Jorge Joaquim (ed.). Sketch-based Interfaces and Modeling

London : Springer-Verlag London Limited ., 2011. — 416 p. —eISBN- 978-1-84882-812-4This book desribe computer drawing. Personal computers became sufficiently powerful in the nineties to support research in sketched-based interfaces in Interactive Computer Graphics and Human- Computer Interaction (HCI). People can now interact with drawings, editing and
augmenting sketches in many different ways. Indeed, electronic drawings can be parsed and converted to digital objects such as pictures, diagrams and 3D models. Sketching can also be used for editing and animating these objects, a feature not possible on paper.
