Title: | Highly stylised drawn animation | Authors: | DI FIORE, Fabian VAN REETH, Frank Patterson, J. Willis, P. |
Issue Date: | 2006 | Publisher: | Springer, Berlin | Source: | Advances in Computer Graphics, Proceedings. p. 36-53 | Series/Report: | Lecture Notes in Computer Science | Series/Report no.: | 4035 | Abstract: | In this paper we argue for our NPAR system as an effective 2D alternative to most of NPR research which is focused on frame coherent stylised rendering of 3D models. Our approach gives a highly stylised look to images without the support of 3D models, and yet they still behave as though animated by drawing, which they are. First, a stylised brush tool is used to freely draw extreme poses of characters. Each character is built up of 2D drawn brush strokes which are manually grouped into layers. Each layer is assigned its place in a drawing hierarchy called a Hierarchical Display Model (HDM). Next, multiple HDMs are created for the same character, each corresponding to a specific view. A collection of HDMs essentially reintroduces some correspondence information to the 2D drawings needed for in-betweening and, in effect, eliminates the need for a true 3D model. Once the models are composed the animator starts by defining keyframes from extreme poses in time. Next, brush stroke trajectories defined by the keyframe HDMs are in-betweened automatically across intermediate frames. Finally, each HDM of each generated in-between frame is traversed and all elements are drawn one on another from back to front. Our techniques support highly rendered styles which are particularly difficult to animate by traditional means including the ‘airbrushed’, scraperboard, watercolour, Gouache, ‘ink-wash’, and the ‘crayon’ styles. We believe our system offers a new fresh perspective on computer aided animation production and associated tools. | Keywords: | Artist driven, stylised modelling, stylised animation, computer animation, computer-assisted animation, NPR, NPAR. | Document URI: | http://hdl.handle.net/1942/1723 | ISSN: | 0302-9743 | DOI: | 10.1007/11784203 | ISI #: | 000239486600004 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2007 |
