Painterly rendering for video and interaction
We present new methods for painterly video processing. Based on our earlier still image processing technique, we “paint over” successive frames of animation, applying paint on...

Line direction matters: an argument for the use of principal directions in 3D line drawings
While many factors contribute to shape perception, psychological research indicates that the direction of lines on the surface may have an important influence. This is especially ...

Performance-driven hand-drawn animation
We present a novel method for generating performance-driven, “hand-drawn” animation in real-time. Given an annotated set of hand-drawn faces for various expressions, our algor...

Virtual Humans Animation in Informed Urban Environments
In order to populate virtual cities, it is necessary to specify the behaviour of dynamic entities such as pedestrians or car drivers. Since it is not possible to construct in real...
