Celtic knots-ironwork art.

Hi, This program will create Celtic knots. Export 2D and 3D (obj, etc..) It may be useful for those designing ironwork art.

Thank you Micione, for sharing this little gem of a program, creates 3D endless knots (celtic knots) for free in OBJ format (and others).
This was a fascinating related site which teaches you how to draw them for yourself.

I would like to create a nice endless knot lamp to print on a 3D printer.

Using JF obj importer plugin for SketchUp did not allow me to import the 3D file, but I was able to open the OBJ into Deep Exploration and export as .skp file.
Which opened perfectly into SketchUp. I know there are other obj importer plugins for SU I was just too lazy to install them.

Then inside of SketchUp:
I used Artisan to subdivide and smooth the geometry. (could have used one or two more subdivides )
Painted the object a color of red (or red and yellow).
Used the Twilight Material Editor Template > Blurry Metal

Then I inserted the Twilight Lighting Studio from the Twilight Render components pack for licensed users.
I turned off the sun light, and set sky to Sky Probe and used the apartment probe from this thread to light the scene.
I set exposure to .5 or .6 in the camera tab, and adjusted the gamma to .9 or something.
Render on Easy 09.

In the second knot, I discovered the 3D geometry options in the program, so eliminated the need for Artisan for subdividing/smoothing.

Hello Fletch, I am glad that you enjoyed the program. Very good, your elaboration. I found several other small "jewels" very interesting. I'm testing them, and soon will send them in sketchucation. So beware, if you're interested. greetings

That would look neat I bet!
