Those of you who follow the GitHub commit logs will note an upload of tutorial material, the first in many a day, month, year, alas. Some ages ago in Deformation (warped fill) #19 I posted a Python-generated animation of epicycles drawing my face. “This should be done in G’MIC” I thought, and from there a Cookbook series on epicycles started writing itself, more-or-less backwards. I thought it might take a month or two to write; alas — Life intervened; the work proceeded in fits-and-starts and was shelved for long periods. So yes — of course! — one may do epicyclic epics in G’MIC, and the course from first principles to the results at hand is an interesting one. At least, I think so.
On tap, I have a Math Expression article that is to be rooted from the tutorial main page, as mathematical expressions are one of those core areas on par with pipelines and image structure. I am making no predictions about when I might post, but it is rather further along than Arabesques and epicycles were when I first undertook that. Hopefully, the COVID related distractions may be mostly behind me. Fingers crossed.
