Sketchbook Week 8: Two-point Perspective You will begin applying what you have learned in class regarding the concept and application of two-point linear perspective principals in this assignment. Keep in mind that the key is remembering that the horizon line (HL) is at the same level as your eyes; you can be gazing straight ahead, up or down, but the horizon line remains true to your eye level. From there, and with regular practice, the rest of material on two-point perspective will fall into place. You will be working with box form (cube) of your choosing; it must have 90 degree corners. I would not recommend working with boxes that have open lids, which are inclined planes, unless you have previous experience working with the principals of linear perspective; if you have prior experience, I encourage you to take on the challenge! Drawing #1 2) Select a carton, such as a cereal box or another smaller in size. Place the box on a table and keep it below your eye level, so that you can see the top of it. Keep the table you placed the box on in one-point perspective to you. Look at the box in two-point perspective with one of the corners of the box closest to your point of view. Use a spot light on it to give it some contrast for you to work with in completing the drawing. 5 minutes. 3) Measure the proportion of the leading plane of the box from your position; use the pencil/thumb method that you learned in class for measuring. Look at your paper and decide where you need to place that measurement based on your position relative to the subject; use your 2H pencil for this (hint: place it below the middle of your sheet because the receding places will be moving vertically up your paper to reach the HL). 3-5 minutes. 4) From where you have placed your first vertical edge, measure the width from the front edge of the box to the vertical on its left side. Using your 2H pencil, place the vertical to that edge of the box at that point: remember those edges will be true verticals, therefore perpendicular to the HL and parallel to the left and right sides of your drawing paper). Sight the angle of the top receding edge between your two verticals and lightly define that using your triangle well beyond the boundaries of your object. Do the same with the bottom edge of that plane; where the two lines meet should be Vanishing Point #1 (V.P. 1) on your HL if you have measured and sighted correctly. Your vanishing point may be off of the Strathmore 400 paper, ending up on the newsprint you have it taped on. 5 minutes. 5) Sight the angle of the other receding plane to the right of your leading vertical at the top edge of the box and draw that in lightly with your 2H pencil; follow that with sighting the bottom edge, again extending both of the lines into infinity (HL). This pair of parallel edges must converge to the same level (HL) as the parallel edges on the left of your leading vertical; where they meet defines Vanishing Point #2 (V.P. 2). If they don’t meet at the same level, you will need to go back and check your measurements and the angles you sighted. Your HL must be on your paper! Again, your vanishing point may be located on your newsprint paper and not on the Strathmore 400. 5 minutes. 6) Establish the ground plane (table) for the box and, using your 2H pencil, draw it lightly in proportion to the rest of your drawing. This ground plane is seen from the same perspective or position in space and must have the same HL! 10-15 minutes. 6) Complete the drawing by laying in general value shapes using the procedure to create your value scale in Week 6; make everything in the box and table that is not white a light gray: leave the negative space white. Using your HB pencil, add another layer of gray to all of the areas of the box and table that are darker in value. Add one more layer of gray using the HB pencil on its side for the darkest areas of the drawing; you can ad another layer with the 3B pencil following that. 10-15 minutes. Drawing # 2 Drawing # 3 2) Follow steps 2-5 from Drawings 1 to complete your drawing. 40-60 minutes.
Three Drawings
Subject: Rectilinear Forms
Materials: 9"x11 3/4" Strathmore 400 paper, 18"x24" newsprint paper, View Catcher, 2H, HB, 3B, 6B graphite pencils, kneaded and gum eraser (finally!), drafting triangle, 24" straight edge.
1) On the two long edges, lightly tape one sheet of 9”x11 ¾” Strathmore 400 Drawing paper in the center of a horizontal sheet of 18”x 24” newsprint paper. Be certain that the Strathmore paper is squared to the edges of the newsprint paper. Using your triangle will help with this.
1) Follow steps 1-6 in Drawing #1 but set the box up so that the top is level with your eyes; you won't be ale to see any of the top, with the exception of the leading edge. What do you find as you sight the top leading edge and that on the left or right that is moving toward the HL? 40-60 minutes.
1) Place the box on the table or desk so that it hangs over the edge of it; you want to be able to see part of the bottom of the box. Sit on the floor so that the box is above your eye level and viewed in one-point perspective from your position.
