A few of the drawn studies I did for an independent study of structural drawing that I undertook this past fall.
Included are images I developed from a cohesion of reference material, and drawings purely of my creation.
Volumetric body structures, here I depicted simplifed forms which constitute the armature of a figure. On the right is a three stage evolution of three blocks stacked atop one another, twisted, and then warped.
On the top half of this page is the schematic of a spiral staircase, and to the right of that is a simplified version.
The bottom half includes a study on head architecture to the left (referencing "Bridgemann's Guide to Drawing from Life"), and on the right is a depiction of how a neck functions in moving the head.
Sketches of body structure
This is a drawing I made showing a three stage evolution of splitting a pyramid and a cube into three parts, twisting the middle section, then replacing them back together
Similar to the twist I drew of the pyramid and cube, this drawing shows the twisting of a cylinder along a grid. The lines mark 45 degree points along the circumference of each end of the cylinder, and as the bottom section remains static, each stage demonstrates one 45 degree rotation clockwise. I think its cool how after the sixth stage the cylinder begins to unwind again
These drawings are all referenced from a book titled "The Curves of Life" by Theodore Andrea Cook, the illustrations of which are illustrated by Pettigrew. Each drawing refrences the page its from. The book and these chosen reproductions demonstrate how curves manifest in all walks of life, and the surprising commonalities between life forms.
These are further studies from the book by Theodore Andrea Cook. The screw forms on the bottom half of the page are referenced from the illustrations by Pettigrew, and I marked the figure numbers alongside them. On the top half of this page are drawings I made based on ideas I was led to from the reading.
More drawings referenced from Cook and Pettigrew
This page, again referenced from Cook and Pettigrew, depicts the composition of fibers within a human femur bone, and how they torque and spiral to construct a formidable structure that holds up the body from the pelvis up.
This is a study from my imagination on the construction of an hourglass along a grid
In this final drawing, I included all the lines from the previous rotation of a cylinder in one rectangular volume using a ruler.
