And most importantly, it is independent from the 3D model rig. The strokes can be easily stored and reused in other characters, allowing retargeting of poses.  ...  This process, whether for key framed or for motion captured animation, takes a lot of time and effort.  ...  Now, the 3D model is ready for the creation of facial poses, retargeting and animation. Facial Posing To create a pose the user need to deform the face model.  ...

Feature points based facial animation retargeting

2008 Proceedings of the 2008 ACM symposium on Virtual reality software and technology - VRST '08  
Figure 1 : The bottom row shows the virtual face animated by retargeting expressions from the source face (top row). Abstract We present a method for transferring facial animation in real-time.  ...  The source animation may be an existing 3D animation or 2D data providing by a video tracker or a motion capture system.  ...  Second, it has to be guided by the deformations of a small number of feature points because our method aims to retarget animations providing by any kind of sources: 2D/3D tracking, 3D animation.  ...

Sketch express: A sketching interface for facial animation

José Carlos Miranda, Xenxo Alvarez, João Orvalho, Diego Gutierrez, A. Augusto Sousa, Verónica Orvalho
2012 Computers & graphics  
One of the most challenging tasks for an animator is to quickly create convincing facial expressions.  ...  In all cases, the strokes do not control the geometry of the face, but the underlying animation rig instead, allowing direct manipulation of the rig elements.  ...  In this way, the user can easily sculpt, retarget and animate facial expressions. Definition and method The method starts by duplicating the original 3D model mesh.  ...

2013 Proceedings of the 12th ACM SIGGRAPH/Eurographics Symposium on Computer Animation - SCA '13  
Additionally, the output of our two-step optimization scheme is also easily editable by an animator.  ...  Figure 1 : Our performance-capture approach excels at capturing and retargeting mouth and eyelid motion accurately.  ...  Pursuing other strategies for rig retargeting is another promising avenue of research, allowing for higher quality performance transfer.  ...

A Survey on Applications of Digital Human Avatars toward Virtual Co-presence [article]

Matthew Korban, Xin Li
2022 arXiv   pre-print
Specifically, the categorization methodology suggested in this paper for avatar-based methods is new.  ...  We hope this study will be useful for future research involving human representation in VCP or Virtual Reality (VR) environments.  ...  We categorize the Online motion retargeting strategies into two types of Rigged-avatar-based motion retargeting and 3D avatar model reconstruction.  ...

Paul Hyunjin Kim, Yeongho Seol, Jaewon Song, Junyong Noh
2011 Pacific Conference on Computer Graphics and Applications  
The new blendshapes are determined to minimize error between the source animation and the retargeting result.  ...  Our method effectively reduces error between the source and target animation, and produces much visually improved target animation without relying on manual intervention.  ...  The method for automatic consturction of a blendshape rig is useful in facial retargeting. However, for a different input sequence, the facial rig has to be reconstructed repeatedly.  ...

Motion Capture Visualisation For Mixed Animation Techniques

Ricardo Megre, Sahra Kunz
2020 Electronic Visualisation and the Arts London Conference  
Our method develops a process to create animation based on mocap data, without being restricted by standard practices that depend on existing rigged 3D models, allowing for visual expression and improvisation  ...  The standard mocap methodology for creating animation consists of retargeting (transferring) the recorded data from actors and performers to existing digital characters, providing them with movement.  ...  Another advantage of this method is that the control rig created is built the same way it would be for creating standard 3D animation.  ...
