Trouble installing hemesh
[1Reply]

- Forum: General Discussion
- Sub forum: Other
I've installed many libraries, thought I'd try out hemesh.
I'm using Processing 1.5.1, Mac OSX 10.7.4

I downloaded it from here:
http://code.google.com/p/hemesh2010/downloads/list

Extracted the \hemesh dir to my libraries folder, where all my other (functional) libraries live.

Starting processing, the "Examples -> Contributed Libraries -> hemesh" is missing. And opening\excuting any of the sketches (from the Finder) gives me this error:

No library found for wblut.hemesh.options
As of release 1.0, libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

Which is of course exactly what I've done.
A snippet of my tree view looks like:
\Documents\Processing\libraries\hemesh\library\hemesh.jar (and several others)
What am I missing here? This seems like such a simple thing, and Processing is failing to detect this libraries existence.

thanks

Export svg?

Searched the forums and the web, not much on this: I'd like to be able to export curves from processing as a svg, and bring those curves into Inkscape as paths.

Currently I'm using Processing's PDF Export library to do this, which works. But it's not perfect: Inkscape will happily import the pdf and generate strokes from the resultant graphics. But the issue stems from the fact if I create an ellipse in Processing (noFill(), no smooth(), strokeWeight() of 1), in Inkscape the given ellipse has a physical width when I 'convert the strokes to path', giving me a shape with one circular path inside the other, filled with black to define the outline: I need to have a single path matching the curve generated in Processing, not 'one path inside another' (giving a donut \ torus effect).

I've been looking for other pdf export options, but not coming up with much. The Processing PDF Export library has this bit of text:
"There is also a contributed library for exporting images to SVG format; check the libraries section of the website for more information."
However I can find nothing that matches this description in the lower docs. Searching online finds the proSVG plugin, however it seems incompatible with the latest version of Processing.

It's quite possible that Processing's PDF export is doing the correct thing and this is simply my ignorance of how Inkscape works. Or maybe it's possible that the PDF export is exporting 'more than it should', and I need another export solution.

Again, my goal is: Make curves in Processing, see the exact same curves represented as paths in Inkscape. And if you're wondering 'why would I want to do this?': It will allow me to generate graphics in Processing and etch them using my Ostrich-Egg Bot, via the Eggbot Inkscape plugins.

Any thoughts? Thanks

Where are sketches saved on the phone, & how to save an image?

So I walked through the whole forum looking for this first, but no dice.

#1: Where on the phone are sketches saved? I know my sketch is there obviously, since I can run it on the phone. But I can't actually find it (using something like Astro File Manager and wildcard searches).

#2: How can you save an image? From regular Processing you can use save(), or saveFrame(): I'm creating a displayable PGraphics buffer which is working fine I have a button (APWidgets, yah!) that will call to buffer.save() to save it... and it seems to work (no errors, no crashes). But searching my phone, I can't find the saved image.

Any thoughts? Much appreciated.

Mac won't detect phone

Recently got a new mac. First mac... ever. So, I'm a complete mac noob. I still managed to get all the appropriate Processing\Android software installed, but I can't get Processing to detect the phone.

I have the Phone's usb development set to "usb debugging" like on my PC. The first time I plugged it into the mac the mac tried to connect to it as a modem (I think that's what it was trying to do?). Then every time after that when I plug it in the phone says "connected", but the mac makes no sign of detecting it. DDMS doesn't see it either

If I instead change the usb settings to "mass storage" and mount the drive, the mac can see it for file transfer, but not for any kind of development (just like on the pc).

So I downloaded this nifty app called adbWireless which lets me connect via adb wirelessly. This works really good in fact: I can connect wirelessly (no more usb needed) and the phone is detected by the DDMS. So I know I'm hooked up.

But when I try to "present" in Processing, I still get the "Waiting for device to become available" message. No love.

Really bummed. Anyone have any ideas?

Sketches don't want to 'quit' on the phone

I've had this problem since I first started putting sketches on my phone (Samsung Captivate, 2.1): Once started, they don't seem to stop. If I either 'present' a sketch to the phone from Processing, or (once it's installed on the phone) I launch it, I can track its status in the Dalvik Debug Monitor. Once started, the processes never seem to turn off. When the sketch is running, if I press the 'back' or 'home' button, I do return back to the phone desktop, but in the DDM, I can still see the process present as running.

The issue is, if I try and launch the app again, it often will misbehave, the most common symptom is having the screen turn black, but the sketch is running (I confirmed this by writing a sketch that had graphics and vibrated... the vibration worked but the graphics didn't). However If I track the "running services" from my phone, the sketch isn't present. So I either have to reboot the phone, or kill the process in the DDM.

Anyone else running into this, and if so, have a solution? It's like the parent Activity doesn't want to quit.

The oddest thing happened yesterday, and I've been unable to recover from it. I'm on a winXP box.

It the middle of working on a sketch and presenting it to the phone, I got the message window "waiting for device to become available". I'd not changed any settings. At the same time the "Auto play" window (like when you put a new cd in the drive) sprang up, and wouldn't go away.

After rebooting both computer and phone with the same results (multiple times), I reinstalled the drivers for my phone (Samsung Captivate). This got me working again. Once. After that the same problem came back. And I'd either get "device not available" or "deceive disconnected" error messages.

Opening up the Davlik Debug Monitor, the status of the phone will filp-flop from online to offline to online, etc.

Again, all of this just happened out of the blue, any thoughts?
thanks

Got multi-touch working

Was easier than I expected it to be based on what the wiki has to say about it ;)
It may not be as 'robust' as other implementations, but it will definitely track multiple points on the screen at once. I've got code and examples over on my blog:
http://www.akeric.com/blog/?p=1411

I override the parent Activity's dispatchTouchEvent method Processing's surfaceTouchEvent and capture the passed in MotionEvent object, which has all different kinds of goodness letting you know what is going on when the user is touching the hardware.

Thanks to a great post on this forum, I was able to build a signed apk for the app I used to teach myself Android\Processing. It's available for download from my blog if anyone is interested.

It's a particle sim responding to touch that triggers vibration when the main particle hits the edges of the device. Merry Christmas ;)

Access the camera's pixels

I've gotten code working that accesses the camera's pixel data in Processing. Wasn't as... straight forward as I'd expected ;) I've got code sample here, enjoy:
http://www.akeric.com/blog/?p=1342

I'd be interested to know how to make it faster. currently running around 1fps (just guessing, not scientific) on my Samsung Captivate.

Big thanks to Ketai: I simply couldn't grok how to decode the YUV bytestream into RGB, so I piggybacked off of a decoder they'd written.

Yeh, I know I could 'just use Ketai' to do what I wrote, but I wanted to figure out how to do it on my own ;)

Code to enable vibration

Had some time this weekend and got the phone's vibration working in a sketch. If you have any interest take a look over on my blog.

Hadn't seen any posts\tutorials on this yet, just wanted to pass it along. Done through Notification and NotificationManager objects. Pretty straight forward.
Samsung Captivate, 2.1
