MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Orthographic Projections: In orthographic projection the direction of projection is normal to the projection of the plane.

Detailed explanation-2: -In three-dimensional geometry, a parallel projection (or axonometric projection) is a projection of an object in three-dimensional space onto a fixed plane, known as the projection plane or image plane, where the rays, known as lines of sight or projection lines, are parallel to each other.

Detailed explanation-3: -July 2019) A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.

Detailed explanation-4: -6. Which of the following orthographic parallel projection is called as a plan view? Explanation: Top orthographic projection is called as plan view. Front, rear and side orthographic projections of an object are called as the elevations.
