I use Processing 3.0b5 and ControlP5 2.2.5.

The size() method doesn't support variables as input anymore. Solution for that is the hardcode the numbers: size(800, 710, JAVA2D);

Apart from that I get an error with ControlP5.
The function "controller(String)" does not exist.

For example with this line: cp5.controller("SAVE_STIPPLES").setCaptionLabel("Save Stipple File (.SVG format)");

I can't find a solution for that.

As you can see, it seems like it's trying to parse the Java version number and failing.

This is the version of OpenJDK which comes with Ubuntu 16.04. This may be a bug in the copy of Processing which is embedded in it, I don't know. I tried to get it working from source using the latest Processing - it does - and then generate a newer version using Export Application but I haven't got that working yet - my exported application crashes for a different reason.

What is going on with the scale factor and the maxSize here? The sample rate across a cell greatly affects the change to the voronoi... but I don't get why, it's not intuitive. None of the papers I've found discuss the tweaking you're doing here. Please break it down for me coz I'm lost and I'd really like to improve my weighting results.

I get that the rate is higher for smaller cells, and I have played with different rates. Bad scaling makes points jump around like crazy or settle into a nearly even grid. The sweet spot is hard to find!

This is more of a generalized question about controlP5. I've forked the repo and I'm working on a project which depends on stipplegen, so I'll be giving this some attention but most of that will be learning the processing environment and community.

It seems from the surface that the UI is refreshed at the same frame rate as the canvas. On my target hardware (which is not cutting edge) one iteration with 4000 dots takes about 45 seconds. If I attempt to change the GUI controls for dot size or white point during that 45 seconds, there is no response.

If I hold down the mouse pointer for 45 seconds on the slider, it will "grab" eventually. It would be a nice feature to decouple the controls from the dot rendering.

Hello, I keep getting an error, I used this software months ago, and it worked fine, I reinstalled it, and nothing wants to work.

As for libraries, I got controlP5 from the processing website.
toxiclibs seem to be impossible to find.

Now I have the libraries. I get this issue. Any guidance?

Hi there,

I wanted to play around with the lowest number of stipples possible, but can only access the following ranges at the bottom end of the scale as the app doesn’t give fine enough control / offer a way of inputting numbers manually.

I can only access:

10, 76, 143, 209, 276, 343 etc.

Thank You,

Simon

Is it possible to uprise the max stipple count of 10000 to much more for example 100K or more?! In a lot of cases much more are needed.

It would be also nice, if we could export the voronoi net also beside the tsp and stipple svg export.

I played the whole night with it and it makes so much fun :)

Best regards! Tungee

Hello, sometimes I find that the UI becomes unresponsive after moving the controls around. Is there a way to run the application via command line with inputs and a file to simply get an output? That would be awesome and I think many other users would benefit as well.

I was wondering if some of the calculations could run in shaders on the GPU to speed up the process?

Thanks.

I have a reqeust regarding the max stipple count of 10000.
I would propagate a much higher max. stipple count, 100000 perhaps?!
Best Regards

It's awesome that you can export the TSP path in addition to the stippling, but the Voronoi cells themselves can look pretty cool too! Would it be possible to add an export option for these as well?

It would be also usable, to be able to export the voronoi cells as a svg.
Best regards
