1. An image processing application implemented to modify facial features of a face in an image using an updated face mesh generated from a combination of deformation fields, the image processing application comprising: a face mesh generator configured to generate a face mesh for the face in the image, the face mesh including landmark points of the face; a deformation field generator configured to construct the deformation fields on the face mesh and combine the deformation fields, the deformation fields including warpable elements formed from the landmark points; the face mesh generator further configured to generate the updated face mesh that includes the combined deformation fields; and a modal control interface to display the updated face mesh, the modal control interface configured to receive an input to initiate modifying one or more of the facial features of the face in the image using the combined deformation fields included in the updated face mesh.
