Ch. 3; Quick Reference; one-point perspective principles
Perspective lines converge to a single ____ ___ located on the ____ ____. The front faces of the cubes and the back wall of a room are viewed parallel to the picture plane. Those elements with faces touching the picture plane can be drawn in scale. One point perspective drawings have true ____, ____, and ____ lines. Items located outside of the ____ of ____ tend to appear distorted. |
Perspective lines converge to a single vanishing point(V.P.) ___ located on the picture plane
1 point drawings have true vertical, horizontal and perspective (depth) lines. Items located outside of the cone of vision (C.V) tend to appear distorted. |

Ch. 3; Quick Reference; two-point perspective principles
|
Perspective lines converge to 2 vanishing points (V.P.s), located on the horizon line (H.L.) Boxes are viewed from the front corner, and rooms generally from the back corner in relation to the picture plane. Two-point perspective drawings have true vertical lines as well as perspective (depth) lines. In 2-point, the front edge (or back edge) touching the picture plane can be measured in scale. Items located outside the cone of vision (C.V.) tend to appear distorted. As with all forms of perspective, items appear to diminish as they recede from viewer.

Ch. 3; Quick Reference; three-point perspective principles
|
Perspective lines converge to 3 vanishing points (V.P.s), 2 located on the horizon line (H.L.) and one usually above or below the H.L. All planes of a box are oblique to the picture plane. All lines drawn in 3-point converge to a vanishing point. No portion of a 3-point drawing can be measured in scale. Items located outside the cone of vision (C.V.) tend to appear distored. As with all forms of perspective, items appear to diminish in size as they recede from viewer.

Quick Ref: estimated one-point interior sketching
|
1. Draw a 10' x 10' square in workable scale
2. Divide the square using diagnos. Draw a horizontal line thru the center; this is the horizong line (H.L); it is at roughly 5' high. Place a vanishing point on the horizon line slightly left or right of center. 3. Draw perspective lines from the V.P. thru corners of the original sqyare, creating wall and ceiling lines. Estimate the depth of the room - make it look squre. 4. Use diagnols to divide the original square which is now the back wall. By dividing th back equally in 4, you will create 30" heigh increments. 5. If necessary, a grid can be estimated thru diagonal division. On side walls, verticals are located where height lines intersect diagonals. 6. Use measureing increments or grid to locate objects and arch. elements. 7. Use clean overlay and create a line drawing. 8. To raise or lower the ceiling, simply draw lines from the V.P. to the appropriate height on the back wall and extend these lines forward. Diagonal extension can be used to enlarge the room. |
