Spiral

Drawing Impulses

With the fern we’ve already approached the spiral. Now I’d like to discuss it in more detail. What can a spiral be? The spiral is a primal symbol. From the observation of nature, it has found its way into science as a geometric shape and for calculating various phenomena. The spiral can move from the outside to the inside, or from the inside to the outside. We’re starting with a spiral that goes from the inside to the outside. The spiral line can move outward at the same distance until your drawing sheet ends. In theory, it could go on infinitely. On the other hand, when you make a spiral going from the outside to the inside, you start by making a circle first. That’s called a limited spiral. There are other possibilities too: The spiral can start from a point and gradually move away from the center, so that the distance from the center becomes greater and greater. There are also spirals which develop from another geometrical body as a basis. For example, you can circumscribe a sphere by drawing a circle and spiraling a line around it from the outside, sometimes stronger, sometimes more delicate. You can do the same with a cone. You can also develop a spiral around a triangle. Or you could draw a square and look how a spiral would develop inside. There are many possibilities.
