How in the fudging heck do people manage to do things like that? I just want to make a rather simple complex curve (quite similar to 1/4 of the surface of a 3D ellipse) for the shoulder pauldrons of Zhang He Armor 2.0, and my attempt at drafting it wound up looking like a deformed cone. Feh. I can probably use my w00t m4th sk1llz to draft a petaled pattern that closes to a spherical surface and then try to mess with it from there.
By the way...I am going to jump into the realm of vinyl-laminated foam for that armor redesign. I do like the mottled paint job on my existing armor, but the OMG SHININESS of vinyl is DAMN impressive, and vinyl lamination is the only way to get a seamless complex curved surface on craft foam. (I am NOT trying fiberglass armor again for a damned long time, thankyouverymuch. It involves far too much calendar time, mess, and effort for my current living situation. I would at least want a workshop first.)
Oh. And speaking of cosplay, I'm working on the content of the upcoming rydain.org. I finished a basic article on craft foam armor, and I'm typing a very longwinded explanation of the construction of Xiahou Dun's Kirin Sword thus far. VERY longwinded. Woohoo. So things are moving along.
