hey forum,
trying to use controlP5 with processing 2.0a4 and the new OPENGL renderer. this gives me the following error:

java.lang.NullPointerException

this can be tested by loading any controlP5 example and putting this to OPENGL mode.

hi,

i am having the problem described here: http://code.google.com/p/processing/issues/detail?id=483

which means i have to try my luck with the processing 2.0a4 alpha version.

i downloaded it, but i cannot get any opengl sketches running now. not in OPENGL, nor in P3D. hm?

can someone help?

is there special things i need to do before being able to run the alpha version?

thanks,

/j

i am on os x 10.6.8 and i get the following error message trying to run the "Earth" opengl example as it is when i load it:

new Client acts strangely

hej forum,
i am working on an installation, controlling video projectors with the client class

everything works fine with my beamers connected, but i would like to be able to catch if the beamers for some reason aren't connected. if i try to create a Client with a non-existing IP, i get erratic results. every second time or so, i get the following error msg:

java.net.NoRouteToHostException: No route to host

and the program continues. other times the program hangs.

is there a possibility of avoiding the program hanging? some try / catch exception trick perhaps?

below is a sample program with the described behavoir:
import processing.net.*;

Client myClient;

String ip = "169.254.100.100";

int port = 10000;

void setup() {

size(600, 250);

println("attempting to open client");

myClient = new Client(this, ip, port);

println("done");

noLoop();

}

void draw() {

println("tut tut");

}

stop() is not getting called

hi all,

i am having trouble with stop(). it nevers gets called.
i can see from this thread: http://forum.processing.org/topic/network-library-possible-to-stop-client-before-application-is-closed

that stop() is not guaranteed to be called, when quitting the program... hm... is there a foolproof way?

for instance, when running+quitting this code, nothing is printed
void setup() {

size(200,200);

}

void draw() {

background(int(random(255)));

}

void stop() {

println("stop");

}

hi forum,
when parsing XML files i get weird results trying to use the getFloat() and getInt() commands -- have the functions been deleted?

i get: the function getFloat() does not exist

even when running the example code from http://processing.org/reference/XMLElement_getFloat_.html i get the same error??

hi all,
i am considering a project where i need to find specific faces on the internet. i.e. point my program to a specific website, give it a face and find matching faces.

something like the iPhoto "faces" feature.

is there a library with this feature? i can only seem to find general facial recognition libraries....

thanks,

sending MIDI time code with rwmidi

[2 Replies]

i am wondering if it is possible to send MIDI timecode with rwmidi?

i am trying to render a processing sketch to disk, while keeping in sync with timing from an external midi sequencer (ableton live) --- since rendering to disk is quite slow, i need to be able to progress the timeline in ableton 1 step once a frame is rendered in processing...

rwmidi has possibilities of sending sysex msgs, which looks like what i need: http://en.wikipedia.org/wiki/MIDI_timecode

but i have no experience with this, and compiling bytes like this seems a bit intimidating. so i guess i am looking for examples of MIDI timecode signals via sysex?

anyone?

autoupdate controlP5?

hej,

i am a big fan of controlP5, and i have used it for some projects now. there is something i can't figure out though.

i would like the controlP5 controllers to update automatically when i change the corresponding values in processing. so something like this:
2. import controlP5.*;
3. ControlP5 controlP5;
5. int intSlider;
7. void setup() {
8. size(400,400);
9. controlP5 = new ControlP5(this);
10. controlP5.addSlider("intSlider",1,20, 5, 10,10,50,15);
11. }
13. void draw() {
14. background(0);
15. intSlider ++;
16. intSlider = intSlider % 20;
17. delay(100);
18. }
should result in the slider moving continuously.

but when running this, nothing is updated / the slider is fixed on its initial value.
i know i can used setSlider(), but when having many sliders + values this becomes quite cumbersome.

is an autoupdate possible?

thanks,

recompiled library is ignored

hej forum,

i am hacking a bit on zeni's animataP5 library for processing trying to implement a few new features.

i have the source in eclipse, and i am compiling the new library straight to my libraries folder, using the library template from the wiki: http://code.google.com/p/processing/wiki/LibraryTemplate

i am very new to eclipse, so i am unsure if i am doing something silly....

when i run the ant build, all looks well, the build completes and the library file is updated in my libraries/AnimataP5/ folder.

but processing is ignoring the new library???

i added a dummy function to the new library to check if it is actually active in processing, and when i call it i get a "the function xx() does not exist" error.

i can see my file is updated by the change date in the OS.

so i am thinking processing must be linking to some other file. i did a search on my computer for the library .jar, but the one in libraries is the only one i can find.

hm....

to further test i installed the recompiled library fresh on a different computer, and on this computer my dummy function exists!

any thoughts?

best,

jacob

turning openGL() smoothing off

this is really bugging me out:
i can't turn off the openGL smoothing.... i would like to draw images to screen with the benefit of openGL speed, but with no smoothing. (i like hard edges)

i found that noSmooth(); is no longer operational, and that i should use the hint(DISABLE_OPENGL_2X_SMOOTH); command, but this has no effect on the result.

below is a simple program showing my issues:
import processing.opengl.*;

PImage smiley;

void setup() {

  size(400,400,OPENGL);

  smiley = loadImage("data/smiley.png");

  hint(DISABLE_OPENGL_2X_SMOOTH);

}

void draw () {

  image (smiley,200,200,100,100);



  float w = smiley.width*8;

  float h = smiley.height*8;



  noStroke();

  beginShape();

  texture(smiley);

  vertex(0,0,0,0);

  vertex(w,0,smiley.width,0);

  vertex(w,h,smiley.width,smiley.height);

  vertex(0,h,0,smiley.height);

  endShape();

}
this should give some nice big pixels, no? as you can see i tried both with image command, and using the image as a texture as well.

but the result is smoothed:

here is the smiley, if you want to run the code:

can anyone help me out?

i am on a macbook pro 13" which has a NVIDIA GeForce 9400M graphics card.

thanks!

automatically add controllers to specific controlWindow in coltrolP5

[2 Replies]
- 27-Dec-2010 03:36 AM
- Forum: Contributed Library Questions
i really like the easy set up of controlP5. using controlWindows makes things a bit more complex though...

is there a way to add sliders, knobs etc to a specific controlWindow automatically?

right now i am doing:
1. controlP5.addSlider("x_gravity",-5,5).linebreak();
and then i have to
1. Slider s1 = (Slider)controlP5.controller("x_gravity");
2. s1.setWindow(controlWindow);
for each slider / controller.

is there a way to automate this?

if not a way to automatically add sliders to specific controlWindows when added, then possibly a way to iterate through the sliders and then assign them all to the wanted controlWindow?

thanks,

rwmidi Controller class conflicts with ControlP5

hi forum,

i am having some problems with running rwmidi and controlP5 together -- they both have a Controller class, so when trying to read midi controllers with rwmidi while running controlP5 i get an:

"the type Controller is ambigious" error

is there a way to redefine the name of one of the Controller classes?

(i suppose editing the source of one of the libraries and then recompiling it all, i tried this in Eclipse now, but i dont really know the program and i have trouble even compiling. grrr.)

gestalt resource files

hej new forum!
i am looking through the gestalt library and src files. i can find some really nice examples in documents/Processing/libraries/gestalt_p5/src/gestalt/demo/ as java files. but i can't find the resource files. every time the examples call some external files like
1. Resource.getStream("demo/shader/simple.vsh")
the files are not included.... is this intentional? or is there a way to download them somewhere?

best,

jacob
