3 Repeating Objects In Perspective A Establish Eye-level () and the closest edge (corner) of the first object (A). (The placement of the first object s corner is arbitrary. Use HEPM system)

4 Single-Point Perspective: Repeating Objects Line establishing the width of the first object B A Establish the width of the first object (line B). This line also represents the closest corner of the next object. The width of the first object is arbitrary. (When drawing actual objects, use the HEPM system to determine height and width of the first object.)

5 Single-Point Perspective: Repeating Objects Line establishing the width of the first object Mid-Point (MP) B A Measure and establish the object s mid-point (MP) height between the bottom and top of the object at its nearest edge. It must be equally split from top to bottom of the line.

6 Single-Point Perspective: Repeating Objects Line establishing the width of the first object a Mid-Point (MP) Establishes the width of the second object C B Intersection of lines (a-c) and (B) at (MP) A To establish the width of the second object, draw a diagonal line from the first object s top corner (a), intersecting the mid-point line (MP) at line (B) to the bottom converging perspective line at (C).

7 Single-Point Perspective: Repeating Objects a Line establishing the width of the second object. Line also represents the closest corner of the third object. c b Mid-Point (MP) Intersection of lines (a-c) and (b-b) at (MP) C B A To establish the far corner of the second object (also is the closest corner of the third object), draw a vertical line from (C) up to meet the converging perspective line at (c).

8 Single-Point Perspective: Repeating Objects a b c Intersection of lines (b-d) and (c-c) at (MP) Mid-Point (MP) Establishes width of third object D C B A To establish the width of the third object, draw a diagonal line from the second object s closest, top corner (b), intersecting line (c-c) at the mid-point line (MP) to the bottom converging perspective line at (D).

9 Single-Point Perspective: Repeating Objects a b c Line (d-d) establishes width of third object d Mid-Point (MP) D C B A To establish the furthest edge of the third object, draw a vertical line from the bottom perspective line at (D) up to the top perspective line at (d).

13 Repeating Objects: #2 Approach Equally Spaced Division of Objects This approach is useful for quick location of objects that are equally spaced. Still need to establish: Location of the closest corner Height of the first object (or corner) The distance above and below Horizon Line (E) the first object is placed Horizon Line () Vanishing Point (VP) The number of objects The total length of the row of objects Height and vertical placement of the last object

14 Repeating Objects: #2 Approach Equally Spaced Division of Objects If you are trying to draw an actual scene, you will need to use the HEPM system for all measurements. If you are drawing to create a scene, make the measurements that work for your purpose. Locate the closest corner of the first object. Decide on the height of the first object (or corner). Decide on the distance above and below the first object is placed. Draw the horizon line (). Nearest corner of first object

15 Repeating Objects: #2 Approach Equally Spaced Division of Objects If you are trying to draw an actual scene, you will need to use the HEPM system for all measurements. If you are drawing to create a scene, make the measurements that work for your purpose. Locate the placement of the last object or the farthest corner of the last object. Decide on the height of the last object. Last object Decide on the distance above and below the last object is placed. Nearest corner of first object

If you are drawing to create a scene, make the measurements that work for your purpose. VP Last object Draw converging perspective lines to locate the vanishing point (VP). Nearest corner of first object

28 Class Demonstration: Repeating Objects

29 Repeating Objects: Class Demonstration 1. Determine () and (VP) and closest corner Do not use your handout grid. Both of the methods below use the hand-eye proportional measuring system (HEPM) to create a grid on the paper. MEHTOD ONE Create your grid with () and (VP) to draw perspective lines to establish your horizontal warehousing rack lines. 1. Establish your picture frame (HEPM) 2. Establish your horizon () w HEPM 3. Establish your vanishing point (VP) 4. Draw converging perspective lines use HEPM 5. Establish vertical right corner of structure 6. Determine how far below () bottom of shelf 1 is 7. Determine how far above () the top of shelf 3 is 8. Split the height distance between three shelves 9. Draw perspective lines for bottom, shelves, & top METHOD TWO Use the horizontal warehousing racks to establish your horizon line () and our vanishing point (VP). 1. Establish your picture frame (HEPM) 2. Draw a vertical line for the nearest corner of racks 3. Mark point on line where you want your bottom 4. Mark another point where you want top of shelf 3 5. Divide vertical line with two more points for shelves #2 and #3. Mark a point for 6. Determine where you want vanishing point (VP) 7. Draw perspective lines from the three shelf points and the top to the (VP). Also draw line. 8. Is your () properly placed? If not, adjust it up or down and redraw your lines Make this shelf the top (roof) of structure The floor is the bottom of the structure Shelf 3 Shelf 2 Shelf 1

30 Repeating Objects: Class Demonstration 2. Determine width of shelves 1. Measure full height of nearest corner (from floor to top). Divide measurement in half 2. Mark the Mid-point (MP) on the nearest corner 3. Draw line from (MP) mark to (VP) 4. With HEPM system, determine width of first bay of shelves (This where you need to remember your unit measurement.) 5. Mark width of first bay of shelves on bottom perspective line 6. Draw vertical line from bottom to top for width of first bay of shelves 7. From top of structure s nearest corner, draw diagonal line, angled downward through (MP) so it intersects the second vertical line (width of first bay of shelves). Finish line to meet bottom 8. Where diagonal line meets bottom, determines width of the second bay of shelves 9. To determine width of third shelf, draw a diagonal line from top of second vertical line (beginning of second bay) through to where it intersects with (MP) and continue down to the bottom. This establishes the width of the third bay of shelves 10. Draw vertical line up from that point to the top of shelves 11. Continue for creating more shelves Make this shelf the top (roof) of structure The floor is the bottom of the structure Shelf 3 Width of first bay Shelf 2 Shelf 1
