1.	Any convenient co-ordinate system or Cartesian co-ordinates which can be used to define the picture is called ___________(a) spherical co-ordinates(b) vector co-ordinates(c) viewport co-ordinates(d) world co-ordinatesThe question was asked in quiz.This question is from Two Dimensional Viewing in division 2D Transformation and Viewing of Computer Graphics
Answer» The correct CHOICE is (d) WORLD co-ordinates To explain I would say: World Coordinate Systems (WCS) are the type of coordinate systems which describe the physical coordinates associated with a DATA array, such as sky coordinates. It is also used to denote wavelengths of a SPECTRUM and to draw astronomical images.
