Process and system for generating personalized facial masks

A system comprising:

• at least one hardware processor;
• and
• a processor-attached non-transitory computer-readable storage medium having program code embodied therewith, the program code executable by the at least one hardware processor to:
• provide a three-dimensional (3D) reference model representative of a human face,
• identify in the reference model a desired contact area circumscribing one or more facial regions,
• generate a digital design model of a contacting interface, the digital design model having a perimeter configured to provide a continuous air seal along the desired contact area of the reference model,
• receive a 3D facial target model corresponding to the face of a subject,
• align the reference model with the target model,
• perform an elastic transformation of the reference model to conform the reference model to the target model,
• modify said perimeter of said digital design model based on the transformed reference model, and
• use said modified digital design model to generate a set of manufacturing instructions for a contacting interface personalized for said subject.
