The creation of realistic 3D human body animations is one of the most challenging research topics of investigation in the domain of the 3D animation, as it constitutes an extremely time-consuming task that requires significant technical and creative expertise. The motivation of this research project is to develop a tool to simplify and automate the creation of human 3D movements by enhancing a 3D graphics creation tool. The proposed tool semi-automates the creation of human character animation, by specifying the starting and ending states and movement styles of a human avatar and the transitionary motion state between them.
