Linear deformation on 3D face model for facial animation

Abstract

Facial animation an important part in the 3D virtual world which is the process of moving the character's face in 3D according to the joint motion that follows the reference human face. Importance of expression in the world of animation is a manifestation of its life an animated character. Importance of expression in the world of animation is a manifestation of its life an animated character. Use the data feature-point to capture facial movements, will be able to put the location of point features 3D models to follow the movements of the human face feature. To overcome facial deformation source with the character's face, Linear Blend Skinning basic methods need to be used so that the deformation process can still display the facial characters expressions were reasonable or natural. Using clustering data clustering as membership data each centroid as the area affected by the deformation. Transformation of linear deformation using LBS has a good ability in determine the amount of change in the new coordinate point in accordance with changes in human facial expressions. The change capable of to properly visualized in the form vertec or scatter-data or using a polygonal mesh. With these visualizations can be shown by good deformation.
