Can someone help me create a spiral (helix) similar to the one shown in the image? How might this be done except from drawing the curves perfectly by hand?

I achieved the desired result, but very painstakingly by drawing everything from hand. See the pictures below. To specify my question: Is there a simpler way to draw a shape similar to this?

I have made a tool that (jooGraphFunction) allows you to graph mathematical functions as curves. As part of the documentation, there is a example of how to do this as well as instructions on how to run scripts.

I will summarize the script briefly here for sake of completeness and posterity should my bitbucket account go under or change too much. The parametric function for a circle is

``````cos(t)
sin(t)
``````

You will want to squish that equation a bit to make it look as if seen from side. Or you can use orthographic projection in which case the equation becomes:

``````0.86605 * cos(t) - 0.86605 * sin(t)
-0.5 * cos(t) - 0.5 * sin(t)
``````

Then add variables for size and just slide it upwards as much as you like for a final equation of:

``````0.86605 * radius *cos(t) - 0.86605 * radius * sin(t)
