| description | We propose a technique to enhance emotional
expressiveness in games and animations. Artists have used
colors and painting techniques to convey emotions in their
paintings for many years. Moreover, researchers have found
that colors and line properties affect users' emotions. We
propose using painterly rendering for character sequences
in games and animations with a knowledge-based approach.
This technique is especially useful for parametric facial sequences. We introduce two parametric authoring tools for
animation and painterly rendering and a method to integrate them into a knowledge-based painterly rendering system. Furthermore, we present the results of a preliminary
study on using this technique for facial expressions in still
images. The results of the study show the effect of different color palettes on the intensity perceived for an emotion
by users. The proposed technique can provide the animator
with a depiction tool to enhance the emotional content of a
character sequence in games and animations. |
