The stereo plotting instruments are generally manufactured on the principle of A. Optical projection B. Optical mechanism projection C. Mechanical projection D. All the above

Optical projection
Optical mechanism projection
Mechanical projection
All the above

The correct answer is: D. All the above

Stereo plotting instruments are generally manufactured on the principle of optical projection, optical mechanism projection, and mechanical projection.

  • Optical projection is a method of projecting an image onto a surface using light. This method is often used in stereo plotting instruments to create a three-dimensional image of a two-dimensional object.
  • Optical mechanism projection is a method of projecting an image onto a surface using a mechanical device. This method is often used in stereo plotting instruments to create a three-dimensional image of a three-dimensional object.
  • Mechanical projection is a method of projecting an image onto a surface using a mechanical device. This method is often used in stereo plotting instruments to create a two-dimensional image of a three-dimensional object.

Stereo plotting instruments are used in a variety of applications, including:

  • Engineering
  • Architecture
  • Mapping
  • Cartography
  • Geology
  • Mining
  • Construction
  • Surveying
  • Planning
  • Design
  • Art
  • Animation
  • Filmmaking
  • Video games

Stereo plotting instruments are a valuable tool for creating accurate and realistic images of objects and scenes.
