Reverse engineering
➔ 역공학(逆工學)
➔ 시스템의 기술적인 원리를 그 구조분석을 통해 발견하는 과정
➔ 기계 장치, 전자 부품, 소프트웨어 프로그램 등
➔ 상업적 또는 군사적으로 하드웨어를 분석한 것에서 시작
➔목적은 원본 생산의 절차에 관한 지식이 거의 없는 상태에서
➔최종 제품을 가지고 디자인 결정과정 추론

3D scanning
➔ Point cloud - 대상물체 표면으로부터 샘플링한
점들의 집합
➔ Multiple scan- Field of view에 따라 여러번의 스캔
➔ Reconstruction- 일반적으로 point cloud에서
NURBS 모델 생성
➔ Contact / Non-contact- 디지타이저 / 스캐너
