I란 무엇인가요?브로우 라이저?

눈썹 안쪽 올리기, 또는 AU1은 페이셜 액션 코딩 시스템 (FACS) action unit (AU). Its function is to raise the medial brow/forehead area, and its action is triggered by the contraction of the medial region of 전두엽. It can difficult find clean references 이너 브로우 레이저. When building FACS references, many sources fail to:

FACS 참조 및 잘못된 정보

I recently (2020) critiqued a set of FACS shapes for a client and noticed his 이너 브로우 레이져 모양에는 골판지( 눈썹 아래)가 실수로 섞여 있습니다.

Client’s Inner Brow Blendshape + My Notes:

다음에 골판지 추가 이너 브로우 레이져 는 매우 흔한 실수입니다. 이러한 공통점은 부분적으로 다음과 같은 사실 때문입니다: 좋은 레퍼런스는 찾기 어렵습니다!

Even my client – an established industry artist with a great portfolio and CV – unknowingly added corrugator features to his model, because he trusted a tainted reference. The reference he used was from a prominent anatomy and facial expression book: 얼굴 표정의 해부학. Many art students and professionals use this textbook. It is a great textbook, but some of its FACS shapes are inaccurate.

Reference used by client:

See the vertical and wavy lines in the center of the forehead in the images below? Those vertical lines are from a brow knitting muscle known corrugator supercilii.
