Chapter 10, Problem 3SI

Explanation of Solution

The condition with example for which a sphere in the scene does not produce a circle on a projection plane:

Vision, as we know, is comprised of 3-dimensions viz. height, width, and depth.

However, there are some ways of representing an object in which it doesn’t display all the three dimensions.

However, there are forms of representation which are limited in that they would not reproduce all the three dimensions. In most such cases, the dimension that's missed is that of depth.

Let us look at the given examples:

  • In the case of designing a layout of a magazine page, while we can experiment with a variety of shapes, sizes and even colors, the depth is limited to the thickness of the medium i.e. paper which is negotiable and hence in this case, it's 3D graphics applications.
  • While drawing an image in Microsoft Paint we are limited only to the X and Y axes
