I recently posted a video of an artichoke which demonstrates how I do an armature drawing to show the surface contour. One of my enthusiastic blog readers sent me a drawing that she did of a pumpkin and was having trouble understanding how she could improve the drawing. Here is copy of the drawing that she sent me.
The first thing I did was redraw the stem and get the elliptical shape working properly. Then I found the center of the stem where it joins to the center of the pumpkin. In my drawing this is the red dot. From there I estimated where the center point of the bottom of the pumpkin was. I then drew a line (in blue) through the center of the stem as well as the center of the pumpkin. This establishes the AXIS of the pumpkin. All longitudinal lines must converge to the center of the axis at BOTH POINTS. As you can see in the first drawing the longitudinal lines do not end at the point of the axis. As soon as the lines converge into the 2 points the drawing begins to come to life and is less confusing.
The lines that go around the pumpkin the width of the pumpkin are the latitudinal lines and they must also follow the surface contour. If the pumpkin was a cylinder or a sphere like an apple, the lines would simply be a series of ellipses that change size as the shape becomes wider or narrower. This is not the case with the pumpkin as the sections are convex throughout the entire shape. The latitudinal lines show the undulation of the form.
I hope this helps to further solidify how surface contour works within a complex form. Many thanks to my blog reader for allowing me to share this with others.
