Nice work Aaron. I’ve thought about doing something along those lines for awhile but I’ve never had the time. Are you familiar with an old Dover book by George Bain called Celtic Art: Methods of Construction?
I am not, but I will check him out! I really just love the line work of most celtic designs; clean, intricate, consistent… That’s what got me! Moving 2D designs with overlapping geometry into 3D seemed to be the next logical step… of course, this took about 3X as long as the same design would have in Illustrator and about 10X as long as if it were had drawn… but then it wouldn’t have been so shiny!!
I, too, have always been a fan of Celtic knotwork (and have that Dover book in my library.) I modeled a Celtic knot, a couple of years ago, posting it to the warehouse. The model includes layers that depict my progression in developing the knot. It might be of help to interested readers trying their hand at weaving similar knotwork:
That IS impressive! I ended up drawing the 2D representation on three “levels”, then I locked those groups and drew the path of the two lines back and forth, from one level to the next. I ended up with a much looser knot, but it kept the look I was shooting for (kind of like a celtic knot made from exhaust pipes). Very nice!
I think sinusoidal paths are the ideal shape for something like this … arcs (and even ellipses) don’t quite give the same result. I’ve experimented with wrapping a sine into a spherical helix to create a “celtic sphere”, but it looks more like a basket weave than a knot
