• Icosahedron. A three-dimensional geometric shape having 20 faces where each face is in the shape of a triangle.
  
  
• Image Editing Program. Software designed to open and modify bitmap images. These include digital photographs, scans, and other digital artwork stored as a series of pixels in an image file.
  
  
• Image File. An assemblage of individual pixels that make up a digital image such as a scanned photograph. When an image is scanned, the computer divides it into tiny little regions and records both the color and the light/dark value of each region. These values are then assembled to create a digital image file. Because of the large amount of information being recorded, image files can take up a lot of disk space. See also CMYK, Grayscale, Monochrome, RGB.
  
  
• Inclined Line. A line that is parallel to only one principal plane of projection. Inclined lines are non-normal lines.
  
  
• Inclined Plane. A plane that is not parallel to any of the principal planes of projection but is perpendicular to one plane of projection. Inclined planes are non-normal planes.
  
  
• Incomplete View. A view that is "cleaned up" to eliminate unnecessary hidden lines. Sometimes an object is so complex that including every single hidden line would produce a very "busy" and potentially confusing drawing. In this case, some of the hidden lines may be omitted in an effort to produce a cleaner drawing.
  
  
• Interpret. To examine and analyze a photograph to understand exactly what is being depicted. Interpreting photos is a valuable skill that can help a modeler extract critical information that can be used to accurately recreate the subject.
  
  
• Intersection. The location where two surfaces meet in three dimensions. An intersection in 3D space is defined by a three-dimensional line. This line can then be projected into any orthographic plan view. Plotting intersections accurately can be one of the most challenging aspects of model design. 3D computer modeling tools can be invaluable to this process.
