File Types

Question 1

Explain two advantages of using VRML over other graphic media files.

Answer 1

• Allow user to interact with the website
• It is a more visual graphic than a static 2D graphic ie
  JPEG
• Allow the user to view inside and outside of the caravan
  model as a virtual experience
• Let the user navigate the 3D model/environment using
  the keyboard and/or mouse

Question 2

Describe how using a VRML format may increase interest for the product and create sales for the company

Answer 2

Using VRML;

• Potential buyers can interact by viewing, moving, rotating
  and within the interior caravan 3D scene, allowing 360
  degree viewing capabilities
• Potential buyers can view specific room/sections of the
  caravan and use controls to move the room as you would
  experience it if you were walking through in real time
• Potential buyers get a more realistic experience of the
  product than from a 2D graphic

*Any of these reasons would increase interest in the product
and potentially lead to sales for the company.

Question 3

Describe three advantages of vector images compared to raster images.

Answer 3

• Much smaller file size compared to large raster images
• Can infinitely zoom in on arcs/curves/circles/splines
  and they remain smooth
• Zooming, lines and curves will not get wider
  proportionally
• The parameters of objects are saved and can be later
  modified — this means that modifications will not
  reduce the quality of a drawing
• Pixilation can occur in raster images
