None of the Unfolding examples run with Processing 2.0b5 and b6. Replacing the GLGraphics calls in size() with any of the following:

size(100, 100);
size(100, 100, P3D);
size(100, 100, P2D);
size(100, 100, OPENGL);

gives the error:
You need to use "Import Library to add processing.core.PGraphics3D to your sketch"
These changes run correctly under Processing 1.5.1. A quick glance at the source suggests that PGraphics3D has been moved to processing.opengl but I'm don't really feel qualified to advise further than that.

It seems that recently there have been some updates (Java? OpenGL? something else?), so that Unfolding does not work properly on Ubuntu anymore.

Please check, and verify library versions.

@sotte Please take a look, too.

I included the javadoc and added a (temp.) link in the header. Can you find a better way to include this?

See _include/themes/unfolding/default.html in line 65.

map.zoomTo() directly uses internal zoom method, but could use events to fire zoom method (resp pan etc). Advantage would be that all interactions work in the event system, e.g. a listening second map still could react to it.

(potentially)

When rendering markers in GLGraphics, the result is slightly different than applying the same drawing methods directly onto the canvas.

Top is the marker, bottom is the direct one. Each one is a red circle with a text label.

On the left you see there is no difference with Processig2D renderer, but on the right with GLGraphics there is a slight color difference, and some weird problems with the circle border.

(This is not due to some sub-pixel render problems. In both cases, the coordinates to draw for have been rounded.)

All events are registered (broadcasting and listening) to one EventDispatcher. We are using only one, anyway (and I cannot think of a scenario where two or more would be useful).

For better performances my program needs to check in advance if a Marker is inside of one of a list of SimplePolygonMarkers.

Concrete Example:
I have a list of countries and a list of airports. I only want to display the airports of the country I hover. When I check at runtime, it's getting real slow. But if I would have the chance to sort the airports by country in advance I think it would be faster.

And I think it would make more sense if one don't have to get the Location of a given Marker parse it into a ScreenPosition to compare it to the Location of another Marker.

Or am I completely wrong?

There are three different examples using the same dataset. One is reading gpx and speed manually, one using markers via the (core) GPXReader without speed, and one uses markers via the extended GPXSpeedReader.

If you use a custom map tiles set in the Processing IDE you need manually copy the SQLite jar to the code or library folder and then point with an absolute path to the TileMill mbtiles file. Maybe there is a easier solution for that?

Is there any known sorting criteria for the examples overview on the page? I don't get it.

Example: 2 Overview + 1 Detail
One static and one dynamic overview map

Example: Overview + Detail with Viewport
Overview and a detail map with viewport finder

Example: Connection Marker
Drawing connections between locations via extended Markers

Example: Overview + Detail
Simple overview and a detail map

At the moment, log4j is not configured correctly, i.e. Processing does not find the log4j.properties in the class path.

Problem mit den hohen Zoomstufen beim aktuellen OpenStreetMap Style. Wichtig für Tutorials.

For polygon marker with very small sizes, i.e. just a couple of hundred meters afar the polygon shape stays transparent. The stroke lines between the single vertices are correctly displayed.

It might be due to some PGraphics behaviour, that polygons which have no dimension in normal, unscaled view will not be filled. In Unfolding we are scaling the (inner)map a lot, if the zoom level is very high. Very weird behaviour.

Add interaction possibilities from KiteConnection to ConvexHull examples. Then, remove (outdated) KiteConnection examples.

Running examples (or other Processing sketches) as Application gives
<Error>: CGContextGetCTM: invalid context 0x0
in the console, but seems to not have any negative affect.

Won't fix, is not an Unfolding bug. Seems to be Java / Mac OS X 10.7.4 (Lion) problem. See http://wiki.processing.org/w/Changes#Known_Issues and http://code.google.com/p/processing/issues/detail?id=1091

At the moment, CompassUI needs to be constructed with the map. We already have an event mechanism in place, which could be used.

Implement MapEventListener, and listen to events in onManipulation(...).
For that, all map manipulations need to fire events, not only user interaction-based ones. (e.g. mouseHandler fires zoom-event on double-click, but time-based automatic rotating does not fire an rotate-event)

I created an ant task to create the unfolding_app_template automatically. First of all, please try it and verify that it works.

ant unfolding_app_template

It compiles all files, builds a unfolding.jar, puts all files for the unfolding_app_template together and zips it (in dist/). Any suggestions?

A few questions:
Currently the following jars are distributed but not used.

• json4processing.jar
• junit-4.10.jar
• libTUIO.jar

Should I remove them?

Furthermore, what should be done with the libNative files. Should we ship all platforms (win/linux/maxosx)?

If right side teaser are shorter than left side, the following row starts with right hand teaser.

Hot-fixed it by increasing the min-height to 380px. Should be fixed for all cases.

Currently, the centroid of a set of locations/vertices tends to move towards borders where many vertices are defined. This is due to the algorithm ("minimizes the sum of squared Euclidean distances between itself and each point in the set").

We need to calculate the correct centroid of a polygon.

Red circle indicates the centroid currently calculated by Unfolding. Green shows the correct centroid.

See (external) MuseApp for the bug, i.e. all marker jiggle on finger interaction.

For example SimpleMarkerApp does not "need" it.

change size(400, 400, GLConstants.GLGRAPHICS); to size(400, 400);

It would be great if we can use the sidebar also in the content. At the moment, it's only used for the teaser row at the top.

In Markdown we could allow some marking to define sidebar content. This could be rendered by closing the current span4-div, and opening a span8-div, putting in the content, closing the span8-div, and opening a new span4-div.

Animated transitions between different zoom levels work, but for panning this seems to be broken.

Fix it!

After using MapUtils.createDefaultEventDispatcher(this, map); we need something to pause the default event dispatcher.

Trying to access tiles from the example results in something like this http://gfzba.cartodb.com/tiles/rivers_ferghana/2/3/1.png?
which says the database table is not existing anymore.

It would be great if you provide credentials for some working map; one which can be used for Unfolding and will be stable.

We need a showreel like https://vimeo.com/6644720

For now, the dist export only creates the Unfolding.jar as well as Eclipse application templates. The export for Processing is needed, too.

Could be inspired by the previously used ant script by Schlegel. Currently, the exported lib does work in Processing, but no full library (incl examples etc) is created.

Creating an UnfoldingMap w/o OpenGL/GLGraphics still needs import of those libraries due to MapDisplayFactory mechanism.

In every case, both libraries are needed. Should be fixed by using reflection.

• marker standart
• marker active
• marker label
• marker image

AnimationWithAniLibApp imports de.looksgood.ani.* which is missing

The rotate event should be used for the TuioCursorHandler.

Hi there,

I'm finding that I can't run any of the examples that come with this library...processing doesn't respond when I press 'run'...how can I solve this?

Copy of the current version from google code project http://code.google.com/p/unfolding/

what do you think about http://jekyllbootstrap.com/ for unfoldingmaps.org

This is mostly a test for the new github notification system.

Did everybody receive this as an e-mail?

In case of more complex MapProviders that actually support different options or parameters, we need a mechanism that allows us to refresh the map, when we change a parameter/option.

I propose, that we set the Options directly with the MapProvider and then tell the Map to throw away caches and reload the tiles from the provider.

Other suggestions / ideas for this?

(My use case are tiles from CartoDB where I can set SQL and Styling options directly in the tile-url, so after changing this, I need to update the Map)

While this functionality is already implemented, the methods are not accessible from the client application.

Create public facade method in Map to switch tile borders, and information.

protected TileLoader createTileLoader(Coordinate coord) {
TileLoader tl = new TileLoader(papplet, provider, this, coord);
tl.showDebugBorder(); // Shows a border around each tile
// tl.showTileCoordinates(); // Shows coordinates and zoom atop each tile
return tl;
}

The JavaDoc mentions a few interesting looking Distorter classes, but it's not easy to figure out how they can be used. An example would be very useful.

Videos do not work anymore in gh-pages.

On the Exhibition main page there still is some code for embedding a video, but that does not work. First, the video.js seems to be missing. Secondly, the values seem to be set somewhere else. Changing exhibition/index.md does not result in a change in the generated page.

Also, we need both options: Add a video in the gray bar (set via page properties), but also in the content section.

I get the following errors

The file "http://a.tile.cloudmade.com/607e6483654b5c47b9056791d607ab74/67954/256/11/1097/672.png" is missing or inaccessible, make sure the URL is valid or that the file has been added to your sketch and is readable.

@cpietsch Is there a new CloudMade ID?

I think we should use githubs project pages and embed the tutorials there. See #3
Furthermore it's really easy to edit the homepage and tutorials if we use github pages.

The wiki is separate from the code and therefore gets out of date really quickly.

What do you think?!

http://stackoverflow.com/questions/624422/how-do-i-document-packages-in-java

Create package-info.java for each package and add documentation.

At the moment, DebugDisplay listens manually to some scopes, as there is no registerToAll(...) method.

An instance of Jenkins (http://jenkins-ci.org/) would be nice to collect code statistics, run unittests, create documentation etc...

@maerzhase pls commit the missing libs for your geonames examples (which are moved to examples-extern) into lib-extern

• added a custom header which looks like the old website.
  @flrn unfortunately i didn't know how to compile the unfolding/assets/themes/unfolding/bootstrap/stylesheets/* into one new bootstrap css file. so i made a custom non bootstrap navigation.
• changed the font size to 14px
• new background
• buttons look different
• footer is black now
• header uses the full width
• here and there stuff

there need to be some changes in the html markup like to put the author in a separate span
