DESN THINKING

MIND / BODY / SPIRIT SUPPORT

Well proportioned cubes are an absolute must as a circle in perspective will need to accurately fit into a square plane of the cube. You will need to be able to accurately locate the center axis and the four cardinal tangents where the circle will meet the square. Practice this for warming up, before moving on to cylinders.

Left. From basic geometry, we understand the four tangents of a circle as it will fit perfectly in a square.

VERTICAL CYLINDERS / HORIZONTAL ELLIPSES

Vertical cylinders are the easiest to begin with. Once you have a good grasp of ellipses in the horizontal plane begin working on well constructed vertical and symmetrical cylinders. Once you have symmetry mastered, then move on to more complex variations such as transitional forms or skewed vases.

BENDING TUBES OR CURVILINEAR PERSPECTIVE

When bending tubes or using curvilinear perspective, align the minor axis of the ellipse to the centerline direction of the tube at that point of the tube body. This will change as you move along the tube. It's a little disorienting at first, but is essentially the same as the basic principle, so keep practicing and it'll get easier.
