The CAD Revolution: Advancements in Holographic Computer-Generated Imaging

The transition from traditional drafting to Computer-Aided Design (CAD) marked a significant evolution in engineering. With CAD, the need for large teams of draftsmen was drastically reduced, enabling single operators to handle complex designs more efficiently. Traditional hand drawings had limitations such as time and labor intensity, requiring complete redrawing for corrections. Enter Holographic Computer-Generated Imaging (HCGI), the next frontier in CAD. HCGI enables the generation of full-sized, manipulatable 3D images within a defined physical space, offering dynamic capabilities for modern engineering projects.

  1. Comp 6626 P2 Turn InRobert L. Baker, P.E.Holographic Computer Generated Image (HCGI)

  2. Computer Aided Design (CAD) Revolution Before CAD, engineering projects often required large teams of draftsman as illustrated:

  3. CAD Revolution Hand drawings have major disadvantages: • Complex drawings are tedious • Labor/Time Intensive • Insertions, deletions, or corrections often require a complete redrawing

  4. CAD Revolution CAD stations significantly reduced the labor volume. In many instances, only a single draftsman is necessary.

  5. CAD Revolution Plotters easily and quickly draw prints thatare notpracticalby hand

  6. CAD Revolution Software packages generate 3-D views that can be rotated or modified at will

  7. CAD Revolution Even the most advanced CAD packages are limited by: • 3-D drawing on a 2-D screen • Most drawings are not full scale • Complex modeling and part placement may still prove difficult

  8. HCGI Objective HCGI is the next major evolution of CAD – generate full sized images that emanate into 3-D space

  9. HCGI Objective Physical limitations abound everywhere. HCGI is no different. Initial objectives are: • Generate static images that can fit within a 6 x 3 x 3 foot space • Rotate, move, place or modify the image or individual components at will • Provide a full color palette
