The thing the Rostock was printing in Make Magazine
TODO: Make the base flat.

A helper function for generating pathnormals

Fix a bug in project()
It was kind of sheer luck that any extrudes worked before this fix.
Also, add rotation to torus_by_extrude, which was an easy way to
reproduce this.

Use "this" instead of the global name

Helper functions for shapenormals

Make extrude's arguments more flexible and powerful
Scott Worley [Fri, 21 Dec 2012 05:40:57 +0000 (21:40 -0800)]
Flip the order of shape,path in extrude args
Scott Worley [Thu, 20 Dec 2012 09:18:52 +0000 (01:18 -0800)]
Cones.
(Cones are the first primitive solid because 3-sided cones are basically
cheap arrows that can be littered all over the place for debugging.)

Pass numeric parameters as numbers

Generalize rotate()
1. Rename the old rotate() to rotate_about_origin().
2. Add a general rotate() that can rotate about any point.
3. Add box_by_rotation.html demo.
Scott Worley [Wed, 19 Dec 2012 13:27:59 +0000 (05:27 -0800)]
Rotate and translate operate on lists of points
Also, change extrude's interface to take 3d points, just with the z
values at zero.

Closed quadstrip: Munge the input, not the output
This is cleaner.

Quadstrips

Do something useful on enter in a parameter field.
Enter in a parameter field now re-generates the model. Previously, it
reloaded the page.
Note: The "go" button is still a button that calls go(), not a form
submit control. This is for debugability. Execution has to make it to
"return false" to prevent submission. For form submits, if an error
happens anywhere, the form submits and uselessly reloads the page.
So the "go" button works differently (better) than enter in a parameter
field in case of errors. This is not ideal, but is functional for now.

A tiny bit of UI shiny: fade-in download link
This helps call attention to it after re-generating the model
with different parameters, letting you know that something changed.
Scott Worley [Tue, 18 Dec 2012 05:42:37 +0000 (21:42 -0800)]
Minimal framework and one box demo.
