Example files

[Windell H. Oskay]

Greetings all,
I'm revising our set of Eggbot example files. If anyone has one or more eggbot drawings that they'd like to contribute for possible inclusion in the next version, please send them to e-mail them to me. Or, post them at Thingiverse and drop me a line with a link, giving me permission to include your file(s).

Thanks!

If deemed appropriate, you have my permission to include the 3200 x 800 Eggbot coordinate demo plot,

http://www.thingiverse.com/thing:5250

(You can include the 3200x1000 one as well, but I don't recommend doing so.)

IMO the world map sample should be reworked, dropped, or given some type of warning -- It's great int theory, but it's a pretty bad "sample."

The plotting order is terrible, there are many unnecessary small islands/polygons given the resolution of the eggbot, and the paths are overly complex for the same reason. It would be a really neat demo otherwise.

I could probably fix it up but I am still pretty green on inkscape and svg at the moment, so I dont want to promise anything. I have some decent GIS data for shorelines and nation boundary lines that I can simplify in Manifold GIS, export to Illustrator, and hopefully get decent paths into Inkscape that way.

Is there some way to manually adjust the drawing order in Inkscape? In Illustrator in the layers pane you can expand each layer to show the depth (and drawing order) of each object/path (which can be further expanded to dig into groups etc.) Is there something similar in Inkscape that I am missing?

Agreed. This is a "legacy" example file that appears to be some sort of converted clip art. I think that someone has already produced a "cleaned up" version of it-- if you're the one that has it, please forward that version to me, and I'll get it wrapped up in the next version.

Drawing order is generally the order that things were drawn in, back to front. I don't know off hand of any standard functionality to show that graphically. However, if you pull up the XML editor window, it will show the different objects in the layer, and you can highlight and re-order them by clicking. There are also some automatic ways to sort drawing order. The Arrange>Restack extension can sort by position (which can be very helpful in minimizing plotting time) and there's also a rather limited "reorder paths for speed" extension that does a first-pass optimization to reduce plot time.

Bruce posted one to the dev list on 17 October 2010 with the
subject line "fast map". I can send it to you if you want.

It's also a pretty bad projection. I'm not sure what it is, but what we need is an "equirectangular" projection. I plotted this one, and it worked out pretty good, but it's way too detailed:

http://en.wikipedia.org/wiki/File:BlankMap-World6-Equirectangular.svg

That one is about the right level of detail for maybe a basketball.

Be glad to add that SVG file-- it's a very basic outline of the
continents (sans Antarctica). No country borders; very few
islands. But it plots in about 2 min., which I needed for the quick
demo on Martha Stewart. (It also could use some "cleaning" -- I know
there's at least one unnecessary PU/PD in it).

If accuracy is a concern, then we really should be aiming for equirectangular, truncated at two lattitudes...

[Benton Jackson]

I agree, truncating equirectnagular at specific latitudes would do the trick.

Here's what the over-detailed one I linked earlier looks like, with antarctica truncated, but nothing truncated on the north. It took over 2 hours to plot. There are some stray marks from false starts, and the pen dragged in a few moves around the middle east, so ignore that.

One thing I couldn't figure out, I changed the size of the image to 3200x1000, and was obviously wrong because the pen arm clunked from end to end. I cut and pasted it to your eggbottempate.svg file (resized to 1000 high), and then it worked fine. What setting is hidden that caused that?

[GoatRider]

How rude, it converted my .jpg files to .tiff

[Dan Newman]

The $2 question is what size was the Inkscape document the first time round? The image size
and document size are two different, independent things. The Eggbot Control extension only
cares about the document size. (File > Document Properties.) Also, in v2.0 and earlier,
the pen was always assumed to be centered along the line y=500 when using "Start with pen centered".
That behavior was without regard to the document size. In v2.1 and later, the pen is assumed
to be centered at (w/2, h/2) where w is the document's width and h is its height. So, in 2.1
and later, the centering pays attention to the document's dimensions. In 2.0 and earlier, it
ignored the document's dimensions.

I don't know about the copy-paste problem (Dan may be on the right track),
but please keep in mind that the vertical scale is a guideline only.

Please see also this wiki page for tips about centering the pen and
determining the actual vertical range for any given setup:

-Windell

[Benton Jackson]

Yah, that's what I meant, "document size", in File->Document Properties. I changed it to 1000 high, and the pen arm bounced off of both the north and south limits.

[Benton Jackson]

Actually, copy-paste fixed the problem. Near as I can tell, both documents were the same size. Unfortunately, I deleted the one that didn't work. I can probably reproduce it by starting from the file on wiki-commons I linked before, and changing the document size.

[John Laur]

I am working on recreating the state outlines sample from scratch starting with GIS polygon data. If the end result is what I expect, I should be able to recreate the world map (with country borders) with the same workflow without too much effort. I don't have my eggbot with me right now, but I want to do a test plot before sharing the file. I am happy to post it and have it included with the samples when complete.

If anyone is interested I am using the wokflow below. It looks complicated, but it only took about an hour. Although I am using proprietary software (some of which is moderately expensive), it is probably possible to do pretty much the same thing with open source GIS tools and Inkscape, but it might be more cumbersome - at least it would be for me since I am more familiar with these.

1) Import polygon data into Manifold GIS [Commercial software].

2) Reproject data into EPSG:4326 (WGS84 Lat/Lon) if needed.

3) Normalize Topology to 0.1125 degrees precision.

    - This is the resolution of a 1/16 microstep on the eggbot, ensuring that the resolution of the map data is at least 1 microstep. 

    - For the US map I am actually normalizing to .05625 degrees since I plan to plot it at 2x scale.

4) Select all polygons smaller than Rhode Island and delete them.

    - In Manifold this is done by looking at the area of the Rhode Island polygon, then using the select toolbar to select "Area" less than the value you type in.

5) Convert polygons to polylines using "Boundaries" transform

6) Split polylines into lines using "Split with [All]" transform

7) Remove duplicate lines (where adjoining polys have created two idential boundary lines) using "Remove Duplicates" transform

    - We should now have single lines where we would have had two overlapping polygon edges before.

    - It is more efficient and looks better if the eggbot draws only boundary lines instead of each polygon's outline.

8) Export the simplified line data from Manifold GIS as an ESRI shapefile.

9) Create a new Adobe Illustrator document and define a map area using the Avenza MAPublisher plugin [Both commercial software].

    - Use EPSG:32663 (World Cylindrical Equidistant [Equirectangular]) projection for the map area.

10) Import the shapefile into Adobe Illustrator using MAPublisher.

11) Manually combine line segments into paths that are more sensible for plotting

    - The idea is to minimize PU/PD events for speed and to avoid right angles when possible.

    - For example, we join the entire US outline together, and we join state borders that follow a common line such as the borders defined by the Mississipi River.

12) Manually reorder and/or reverse the paths in Illustrator for plotting speed (seems easier to do than in Inkscape)

    - Putting arrowheads on each line/path is helpful to know starting points and line directions.

    - The "Reverse" Illustrator script found at http://park12.wakwak.com/~shp/lc/et/en_aics_script.html is very helpful.

13) Export SVGz from Illustrator and open in Inkscape

14) Size/scale the document and artwork as appropriate for plotting

    - Maybe "Reorder paths for speed" would help if run again here -- not sure.

15) Plot -- in theory this will be awesome!

As soon as I test this on my egg-bot I will share the SVG file. If anybody wants the simplified (or unsimplified) shapefile of the state boundary lines I am using, please contact me by private e-mail.

Cheers,

John

[John Laur]

OK I reworked both a USA state map and a world map with boundaries using the technique I posted about earlier, although I did not optimize line directions on the world map. The SVG files are attached (in the zip). Note the world map is 1000px high, so make sure whatever your plotting setup has a 1000 step range on the pen axis. The map is highly compressed when shrunk to 800px high, but you can shrink it or clip the artwork as needed. I attached the full 1600x3200 Cylindrical Equidistant [Equirectangular] projection file marked DONOTPLOT so you can crop or mangle it however you'd like. 

I didn't time the states, but I think it plots in about 30 seconds; maybe less. The full world map plotted in 6:10 on my machine. I am drawing on these tiny golf-ball-size christmas ornaments so it's tough to see the detail; I'd be curious to see a photo of this version of the world plotted on a much larger object if anybody does it.

Feel free to do anything with these files. Again if anyone wants the processed shapefiles or original Adobe Illustrator documents, please email me privately.

John

[Benton Jackson]

That looks awesome! I have some larger ornaments I'm going to be doing with niece and nephew names, when I have my egg-bot adjusted for that I'll pop one of these out and take pictures. I'll use a 005 pigma micron so the detail will show up.

Feel free to consider my work over the Christmas break for inclusion in the example files.  Description of files follows.

-Roland

Pumpkin -- traced by hand from raster source.  The curly has no black outline due to its small size and registration issues in my setup -- it looked better plain.

Merry Christmas -- 3 layers, Hancock font filled using duplicate/inset path method.  Holly leaves and berries drawn by hand.  This file size could probably be significantly reduced due to the repeated elements, but I haven't learned SVG/inkscape well enough yet to make a reference to an object instead of duplicating it.  It compresses well.

Sin waves -- generated by using a GNU bc script to make one wave 5 periods long, then duplicated, simplified, stretched, and placed by me in inkscape "by eye" then using distribute centers evenly function (so if you look closely it's probably off by a couple of pixels -- not noticeable in my output).

Heart - Result of mathematica plot, which had to be traced due to issues with poor path selection when using inkscape import of EPS file.  You can see its source equation here:

http://www.wolframalpha.com/input/?i=ParametricPlot[{12+Sin[u]+-+4+Sin[3u],+13+Cos[u]+-+5+Cos[+2+u]+-+2+Cos[3u]+-+Cos[4u]},+{u,+0,+2+Pi}]

[rgm]

Thank you very much for posting your workflow!  This would be much better for drawing the entire USA, although we should consider is how useful it is to copy/paste a particular state out of the existing us_states.svg file.

Over the holiday break I myself enjoyed very much being able to represent my "home state" and that of my loved ones on an ornament, augmented by state-appropriate logos or clip-art.  (Texas with longhorns logo, Kentucky with corn, etc.)

So although paths may overlap in the current example, the ability to extract a particular state cleanly for individual display is pretty great.  In the future, perhaps this can be best done with an examples structure like:

us_states_no_overlap.svg    <-- your optimized file

US States/Alabama.svg

US States/Alaska.svg

US States/Arizona.svg

...

(A folder containing the individual states)

[rgm]

Turns out that the existing wikipedia "Blank_US_Map.svg" is pretty handy for copy/pasting a particular state's outline too.

http://en.wikipedia.org/wiki/File:Blank_US_Map.svg

[John Laur]

Is the goal to produce good egg-bot examples or a clip-art library? There are plenty of state outlines available online in any format you can think of.

Also the existing USA map in the examples looks to be in either the Lambert Conformal Conic or Lambert Azimuthal Equal Area projection which are popular for flat maps of the USA but not so good for drawing on spheres.

[rgm]

I think you're right, and I had lost that focus.  The primary goal should be to distribute good egg-bot examples that showcase the system, and not to distribute a clip-art library.  OpenClipArt.org and Thingiverse are for clip-art, but the line is somewhat blurred when it comes to clip art that has had careful attention paid to hatch fill densities, path direction, and layering.  Both OpenClipArt and Thingiverse support tags, so maybe just saying "search for tag eggbot" is enough.

That said, I do feel that including some clip art is appropriate, especially if it relates to designs that lend themselves well to ornaments and eggs.  Holly leaves, christmas trees, stars, hearts, other winter solstice holiday imagery (Gravmas?), snowflake tessellations, snowflakes, bunnies in grass, and zig-zaggy lines in pretty patterns.  A few (more) of these would go a long way toward helping a novice Egg-Bot user produce in-season output quickly.

This past Christmas I was playing with Egg-Bot in a remote cabin far from internet access.  Having "Holly.svg" would have saved me a couple of hours -- although I did learn a tremendous amount about Egg-Bot and Inkscape while drawing it.

Thingiverse is really an *excellent* place to upload fully-formatted,
ready-to-rock eggbot files.

Wikipedia is actually a neat source of graphics, because
Inkscape-generated SVG is a preferred for their illustrations. Also, all
illustrations there are freely available, licensed under the GFDL, IIRC.

-Windell

[Dan Newman]

Ahh, you just made my day mentioning "parametric". Some time back
I started to write an Eggbot / Inkscape extension to do parametric
plotting with some built in recognition of the Eggbot's 3200 pixel,
cylindrical horizontal scale and what that implies to periodicity
of plotted functions. With the extension, curves added to the drawing
also receive some hidden SVG tagging that then allows selecting two
previously plotted curves and using them to bound a new curve.

Now that someone else has uttered the term, maybe I'll put some more time
and effort into the extension.

Hi Everybody,

Got my eggbot just before Christmas and had a blast putting it together and
drawing on some eggs, oranges and light globes. I'm a software developer and
am thinking of writing an external application to control the eggbot. I was
just wondering if somebody else is already working on something like that?

Thanks and keep up the good work

[Brian Schmalz]

Tom,

Wonderful!!! We love to hear feedback like this.

There are a couple ways you could go here. You could write some Python extensions and run them in Inkscape. This is nice because you don't have to worry about communicating with the EggBot (as it's already taken care of for you) you just create lines and vectors and Inkscape objects algorithmically. See the examples that are included in the Inkscape Eggbot Contributed menu, like the Eggmazing one (my favorite).

If you want to talk directly to the EggBot, you can find the commands you'll need here : http://www.schmalzhaus.com/EBB/EBBCommands.html
You basically just open up a serial port to the EggBot and send those commands to make it move. You'll have to come up with the lines to send it though.


One thing I thought would be interesting (and really simple) would be a small application (maybe in Java so that it would run on everyone's computer in a browser?) that would allow you to 'draw' in a box on the screen with your mouse, and have your EggBot immediately follow your drawing. Mouse down = pen down. I'll bet kids would like the immediacy of seeing their 'drawing' on the screen mimicked in real time by the EggBot!

Hi Tom,
There's nothing really "internal" about the software that we're already using. The code is open source and written in python. It just happens to have the GUI part written as an Inkscape extension.

* Our existing python code can be made to run stand-alone with a bit of effort (it's already been done for an earlier version).

* There's also an older wxpython fork that provides a GUI outside of Inkscape.

* We also have an example program on the Eggbotcode site written in Processing, and another control system recently contributed that runs in Perl.

* The EBB commands are fully documented, so you can directly control the Eggbot from anything else that can talk to a USB serial port, too.

* Even Inkscape is open source software, so you could potentially fork Inkscape and make Eggbot control built in as fundamentally as fill and stroke.

And yes, it is absolutely possible to write your own stand-alone graphics program that is eggbot-centeric. Absolutely. But there are some benefits to starting with an existing graphics package. In the words of our team members who first added it to Inkscape, no need to re-invent the wheel.

The example that we wrote in Processing does just that, and Procesing *is* Java under the hood. :)

Hi Tom,

I'm a software developer and am thinking of writing an external application to control the eggbot. I was

just wondering if somebody else is already working on something like that?

If you look in the code repo (linked off the egg bot wiki) you will find some perl code I wrote to drive the Eggbot. 

That is "external" code in the sense that it doesn't expect Inkscape to be running, rather it just talks to the Eggbot. There is a program to plot HPGL files and a test program that plots some circles ands squares on the eggs. You could easily adapt it to anything.  I realize perl is opaque for folks who haven't used it though.

Most of the eggbot extensions code is just Python that can run standalone as well, both examples will give you everything you started.

John,

Your world map looks great on a larger ornament. It took about 6 minutes for mine to plot as well, although I didn't time it. Here's what it looks like on a 2.6 inch ornament, drawn with a 005 Pigma Micron:

http://goatrider.com/images/20101230_world_east_equirectangular_sm.jpg

http://goatrider.com/images/20101230_world_west_equirectangular_sm.jpg

It's still a little squashed, it probably needs to be clipped on the north latitude and stretched to fill. Cape Horn appears to be at about the right latitude.

Wow that looks really nice; I'm glad it worked so well -- I may have to get some of those pigma pens.

You are correct in the way the final data is distorted. I projected the map data into a 1600x3200 svg (full spheroid) and then to get to 1000x3200 I cropped out antartica at the bottom, shifted cape horn to the lower extent of the image and then scaled the uppermost islands in the north sea down to the 1000px line. The result is that the map is vertically compressed about 15% and shifted south about 15 degrees. Without this shift, the northernmost extent that can be plotted on the eggbot is only about 56 deg N latitude. Since all of Alaska, a good deal of Canada, Europe, and Asia are above 56 degrees, it would make for a rather boring demo not to have them included despite the distortion.

[John Laur]

Attached is another drawing I made today if you want to use it in the samples, please be my guest. I got some color sharpies, and so this is my first color plot. It is along the same lines as the full-egg tessellation that are already part of the samples. This one is "filled" cubes. It's 5 colors and layered appropriately. I attached a photo of what it looks like plotted onto a large clear glass ornament.

I get a long pause at the start and end of plotting each layer, and then the error "unable to draw object, please convert it to a path first." It still draws fine, other than that. It must be a bit of stray data?

[GoatRider]

Heh, I think I know the long pause part- Layer 1 didn't have much of a
pause at the start, and a long pause at the end. Layer 5 had a long
pause at the beginning, and hardly any at the end. The pause must be
skipping the undrawn part as it scans through the drawing.

I attached a photo of what it looks like plotted onto a large clear glass ornament.

I don't know if this is the sort of thing you're looking for, but here
is an svg file of a ring of bunnies I just made for easter eggs. You
may use it in your example files if it helps.
They look kinda clip arty and you might suspect that I lifted them
from somewhere, (common practice these days), but no . . . I found a
photo of a group of bunnies and singled one out and made a drawing of
him/her in Illustrator with a wacom tablet. Simplified it and smoothed
it over, altering the posture of the bunny so he didn't look so tense.
We all want happy, relaxed bunnies for easter, right?

Agreed. It's the Thanksgiving turkeys I expect to be tense and looking
over their shoulders ;-)

Thanks for posting this. It looks nice. I'm sure my daughters will
have fun using it as the basis for some egg drawings.

Regards,
Dan
