Abstract:
This research represents a proposed system for animating 3D face
models digitally to replicate facial expressions of a human actor. The
rst phase of development is using OpenCV face landmarks detection
algorithm to detect the face of the human, extract the facial features
and landmarks (X,Y) coordinates. There are two approaches of an-
imating the 3D face model. The rst approach is rigging the 3D
model's face in Blender and controlling these rigs in Unity by scripts.
However, face rigging is a challenging complex modelling task. Fur-
thermore, the 3D model is a mesh that consists vertices that connects
together to form triangles that form the nal outcome of the mesh.
Therefore, the second approach used is vertex displacement which is
animating the 3D model by changing the position of its vertices using
Unity scripts. Several key points where added where each key point
is attached to a list of vertices that control the mesh area that is re-
quired to be animated. This proposed system aims to facilitate the
process of animating 3D face models digitally rather than ine cient
hand drawn sketches which are time consuming
