Exercise: Abstract Geometric Design

Create a composition based on the three vertices of a triangle.

.

All of the shapes that make up the structure of the painting below relate in one way or another with three points.  The points were chosen arbitrarily, each one outside the boundary of three sides of the rectangular image space.  A straight edge, a pencil and a piece of string are the only tools necessary.  The string makes a wonderful, easily adjustable measuring device and compass.

.

The short video below shows the method of determining the shapes.

.

.

Three points are chosen, one on the outside of each of three sides of the rectangular picture plane.  The points are connected to created a triangle. A string is used to determine the radii of various arches based on the distance between any two vertices of the triangle.  Any intersection of lines, either straight or curved are acceptable points from which to take another measurement of radius for a new arch drawn not from that point, but moved to a different point so that your new line or arch will not intersect with any other point of intersection.  Switch back and forth between determining new straight lines and curved arches.

.

Continue to divide your shapes until you feel there is a strong composition composed of parts that vary in size and shape.  Try to develop a sense of rhythm and energy, an interaction between your shapes.  This is the skeleton, the foundation of your painting.  When the foundation is strong, it allows for more freedom when you begin to apply color.

This is one of the methods I will be teaching in the upcoming Watercolor Technique Workshop in Santa Rosa, CA on April 25th & 26th at Riley Street Art Supply.  Click here to register: Watercolor Techniques Workshop
