Fast Response and Quick Progressive Transitions using Body Part Motion Graphs

Abstract

Interactive applications where 3D character animation plays an important role need avatars ready to perform different activities. This objective has been accomplished in different works [LCR*02] [ZS09] that look for transition points in motion capture clips to allow transitions between them. These works ensure realism and smoothness but their responses and transition durations depend on transition points. Working with partial motions, such as body part motions, allows finding specific transition points for each part in order to optimize whole body transitions in a progressive way. This can be achieved with body part motion graphs (BPMG’s) [FBM11]. In this work we want to show that progressive transitions generated by BPMG’s have fast response and quick execution. In order to demonstrate this we have compared BPMG’s transitions against standard motion graphs (SMG) transitions. The results we have obtained show that our method allows more reaction velocity and execution. Moreover BPMG’s transitions are smoother than SMG transitions.
