Graphical projection

A graphical projection is a protocol by which an image of a three-dimensional object is projected onto a planar surface without the help of math.

• 

  Various projections and how they are produced

• 

  Parallel projection corresponds to a perspective projection with a hypothetical viewpoint; i.e. one where the camera lies an infinite distance away from the object and has an infinite focal length, or "zoom".

• 

  Symbols used to define whether a multiview projection is either First Angle (left) or Third Angle (right).

•

• 

  Perspective of a geometric solid using two vanishing points. In this case, the map of the solid (orthogonal projection) is drawn below the perspective, as if bending the ground plane.
