Vocabulary
• Horizon Line
– A horizontal line that contains the vanishing
point(s) of a drawing
• Isometric Drawing
– A drawing of a three-dimensional object in
which parallel edges of the object are shown as
parallel line segments in the drawing
• One-Point Perspective
– A drawing with one vanishing point
• Orthogonal (Orthographic) Drawing
– A drawing that depicts a three-dimensional
object by detailing three views of the object
Vocabulary (cont)
• Perspective Drawing
– A drawing made on a two-dimensional surface in
such a way that three-dimensional objects
appear true-to-life
• Two-Point Perspective
– A drawing with two vanishing points
• Vanishing Point
– A point at a distance from the observer where
two or more lines of a drawing appear to
intersect
