renderings of the cartoon from any view. 2.5D cartoon models are easier to create than a full 3D model, and retain the 2D nature of hand-drawn vector art, supporting a wide range of stylizations that  ...  We show how 2D vector art drawings of a cartoon from different views can be used to generate a novel structure, the 2.5D cartoon model, which can be used to simulate 3D rotations and generate plausible  ...  We show a rendering of an exploded view of a 2.5D cartoon model in Figure 2 . In the next section, we will describe the user interface we use to construct a 2.5D cartoon model.  ...

Chih-Kuo Yeh, Peng Song, Peng-Yen Lin, Chi-Wing Fu, Chao-Hung Lin, Tong-Yee Lee
2013 IEEE Transactions on Visualization and Computer Graphics  
This paper introduces double-sided 2.5D graphics, aiming at enriching the visual appearance when manipulating conventional 2D graphical objects in 2.5D worlds.  ...  By attaching a back texture image on a single-sided 2D graphical object, we can enrich the surface and texture detail on 2D graphical objects and improve our visual experience when manipulating and animating  ...  cartoon shown in Fig. 6 (license obtained from www.CartoonStock.com), and also the reviewers for the many constructive comments that help improve the paper.  ...

DOIUnfolding the City: Spatial Preference Based on Individual Demographic Characteristics

Qi Wang, Min Lu, Qingquan Li
2020 IEEE Access  
Together with a cross-filter and flexible 2.5D interactions, the effectiveness and usability of the system are demonstrated well by a study conducted in Shenzhen.  ...  A 2.5D spatial visualization is proposed to maintain a compact multivariable analysis by relaxing the z-axis to encode information, such as visiting frequency, demands, and traveling distance.  ...  The manipulation of the 2.5D view supports users with rotate, zoom, and pan operations, which is continuously flexible so that users can find a suitable observation point.  ...

SD Models: Super-Deformed Character Models

Liang-Tsen Shen, Sheng-Jie Luo, Chun-Kai Huang, Bing-Yu Chen
2012 Computer graphics forum (Print)  
The models from left to right are: baseball cap boy, wolf, armadillo, dinosaur, dog, and lion.  ...  The SD style characters are widely used, and can be seen in many anime, CG movies, or games. However, to create an SD model often requires professional skills and considerable time and effort.  ...  Acknowledgments: We thank the anonymous reviewers for their thoughtful suggestions, and also thank Digimax for providing high quality character models, (Figure 14 (Figure 15 ), "curly hair girl"  ...

MoSculp: Interactive Visualization of Shape and Time [article]

Xiuming Zhang, Tali Dekel, Tianfan Xue, Andrew Owens, Qiurui He, Jiajun Wu, Stefanie Mueller, William T. Freeman
2018 arXiv   pre-print
By automating the process, our system takes motion sculpture creation out of the realm of professional artists, and makes it applicable to a wide range of existing video material.  ...  Given an input video, our system computes the motion sculptures and provides a user interface for rendering it in different styles, including the options to insert the sculpture back into the original  ...  We thank Katie Bouman, Vickie Ye, and Zhoutong Zhang for their help with the supplementary video.

Models for character animation

Gordon Collins, Adrian Hilton
2001 Software Focus  
We present a review of methods for the construction and deformation of character models. We consider both state of the art research and common practice.  ...  In Section 3 we discuss the model building approach which requires no data capture and the scanning approach where models are copies of real objects.  ...  Acknowledgements We thank Robert Kruczera (www.3dcharacters.de) and Taron (www.taron.de) for their character art in Figures 2 and 3 and Jonathon Starck for Figure 5 .  ...

Augmenting Hand Animation with Three-dimensional Secondary Motion [article]

Eakta Jain, Yaser Sheikh, Moshe Mahler, Jessica Hodgins
2010 Proceedings of the 2004 ACM SIGGRAPH/Eurographics symposium on Computer animation - SCA '04  
In particular, we create animations in which hand-drawn characters interact with cloth and clothing, dynamically simulated balls and particles, and a simple fluid simulation.  ...  The driving points or volumes for the secondary motion are tracked in two dimensions, reconstructed into three dimensions, and used to drive and collide with the simulated objects.  ...  Sykora and colleagues [SSJ * 10], employ user-specified depth inequalities to generate a 2.5D popup.  ...

Repurpose 2D Character Animations for a VR Environment Using BDH Shape Interpolation [chapter]

Simone Barbieri, Ben Cawthorne, Zhidong Xiao, Xiaosong Yang
2017 Lecture Notes in Computer Science  
In traditional platforms, 2D animation represents a more economic and immediate alternative to 3D.  ...  A 2D character is actually flat, so there is not any depth information, and every body part is at the same level of the others.  ...  That is because that section of the hair is part of the joint section, thus it is not removed.  ...
