Three Dimensional Facial Expression Generation

In a digital medium environment to generate a three dimensional facial expression from a blend shape and a facial expression source, a method implemented by a computing device, the method comprising:

• detecting, by the computing device, a semantic type defining a facial expression of the blend shape;
• defining, by the computing device, points on the facial expression source as corresponding to points on the blend shape based on the detected semantic type of the blend shape;
• assigning, by the computing device, transfer intensities to the points of the blend shape and the facial expression source, respectively, to form respective points of a plurality of points of the three dimensional facial expression, the assigning being nonlinear for the plurality of points, one to another, of the three dimensional facial expression based on the detected semantic type;
• and
• generating, by the computing device, the three dimensional facial expression from the blend shape and the facial expression source by forming the plurality of points using the assigned non-linear transfer intensities for respective said points of the blend shape and the facial expression source.

In a digital medium environment to generate a three dimensional facial expression from a blend shape and a facial expression source, a system comprising:

• a semantic type detection module implemented at least partially in hardware to detect a semantic type defining a facial expression of the blend shape;
• a transfer intensity assignment module implemented at least partially in hardware to assign transfer intensities to the blend shape and the facial expression source, respectively, for individual points of the three dimensional facial expression, the assignment based on the detected semantic type;
• and
• a three dimensional facial expression generation module implemented at least partially in hardware to generate the three dimensional facial expression from the blend shape and the facial expression source based on the assigned transfer intensities.
