    • From physical to virtual
    • Design developing Physical Virtual 3D scanning 3D model Sketching point cloud clay mesh 3D model NURBS Fabrication Model Design Develop
    • 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 http://www.capture3d.com/ http://www.3dscanning.co.kr/
