obj uploader not effective

I'm trying to use saito obj loader library to upload some of my 3dfiles created in 123d design, exported as .stl files and then exported as .obj files using meshviewer.
Then I tried to upload then in an applet and I'm not getting a blank screen .

I've tried to even follow this guide : http://www.youtube.com/watch?v=6VSaneuiaWs

It's not working.

Can somebody try some complex geometry (Not just basic shapes) and exporting and modifying them using blender and uploading them to the applet window?

I found this tutorial video and lib resp for importing .OBJ 3d files into processing environment through these
links.

http://www.youtube.com/watch?v=6VSaneuiaWs

https://code.google.com/p/saitoobjloader/.

Then to start with I wrote the following code just to upload a simple 3d .OBJ file (made in ble nder's mesh's icosphere )

( Add->mesh->icosphere.)

then I exported the file into .OBJ format as guided in the video.

Th code is:
2. import processing.opengl.*;
3. import saito.objloader.*;
5. OBJModel model ;
7. void setup()
8. {
9. size(1000, 600, OPENGL);
10. //frameRate(30);
11. model = new OBJModel(this, "test3.obj");
12. //model.enableDebug();
13. model.scale(20);
14. model.translateToCenter();
15. noStroke();
16. }
18. void draw()
19. {
20. background(129);
21. lights();
22. translate(width/2, height/2, 0);
23. model.draw();
24. }
I just got a gray screen and nothing on it and following in the troubleshoot monitor of processing:
2. Loading this = test3.obj
3. Loading this = test3.mtl

I've written a code where I use some data coming from Arduino to control the perspective orientation of a cube & control an audio sample using band pass filters & draw the respective waveform. Now the orientation of cube displaces the waveform.

hello everyone! I'm trying to make a speech control like seen in ironman.
I've developed a script in Windows Speech Recognition macros where in when I say-"Hello Jarvis" a keystroke "c" is send. ANd it sends a single only keystroke(I've checked it using notepad. When I say "Hello Jarvis", a 'c' is printed in the text editor)

Now I've developed a processing sketch using "tts lib" wherein, when a keystroke "c" is received, the sketch speaks out a return gesture by saying : "Hello Saurabh".

Now the problem is it keeps on saying that & does not stops.

I've tried opening up a "link" & when I say "Hello Jarvis"- it opens multiple tabs.

Serial data display

- Forum: Core Library Questions
Hello Everyone;

I'm trying to display some simple serial data coming from an Arduino to a processing applet in way such that the continuous data keeps on scrolling down in a fashion similar to the Arduino IDE's serial monitor. In a way you can tell that I'm trying to make a serial monitor in processing with the data continuously scrolling & not fixed at a place & changing .

A sketch which takes care of the later condition of -" fixed placed continuously changing serial value monitor " is given below:

import processing.serial.*;

PFont fontB;

Serial port;

int freq = 0;

void setup()

{

size(680, 420);

port = new Serial(this, "COM8", 115200);

port.bufferUntil('\n');

fontB = loadFont("ArialMT-48.vlw");

textFont(fontB, 48);

}

void draw()

{

background(0);

fill(255);

text(freq, 350, 350);

}

void serialEvent (Serial port)

{

String inString = port.readStringUntil('\n');//reading from serial data until new line

if (inString != null)

{

//conversion of the string into integer

inString = trim(inString);

freq = int(inString);

}

}

Can anybody help me here ps? It's for a project that I'm making & would really appreciate if anybody can guide me here a bit.

Problem on exporting the sketch

hello; I've been facing a problem since the time I installed processing on my system. The issue is, when I export a simple sketch (without having any libraries in it), on double clicking the .jre file, it runs well. But as soon as I start using external libraries in it & then export it, on double clicking the .jre file of the applet, It shows a small window saying on it's heading-" Java Virtual machine launcher " & inside the window a "X" symbol saying next to it - "A java exception has occurred". I've latest java installed in my system.

What can be done about it?

image upload

I'am doing kind of similar stuff. I'm saving frames using the JSVideo lib as JPEG files(from the capture example). Now I need to upload them In the same applet. I can use a ControlP5 for an intuitive UI (I know how to upload images using PImage). But every time how can I upload the latest saved image?

sequence will be like:

. On a click of a button-1, picture will be taken & stored in the sketch's folder.

. On a click of another button-2, the capture window will get closed & viewer window will be opened.

. There two new button will take over the earlier ones as button 3 & 4 resp.

. On clicking button-4, next image will appear in the applet.

. On clicking button-3, earlier image will appear in the applet.

Now I can do all these if I know the no. of image files in that folder & their Ids.

But the problem is if I go on clicking I don't know the current volume & ID.

Any help is appreciated.

Can any body tell me How to use keystone library (for projection mapping) in windows?

As shown in the Keystone lib website, for windows I went to download extra 'Advanced java imaging lib. viz . jai ' through this link;and I'm actually stuck here (Here's actually so many, I'm confused to choose from) .
A snap shot of the page

Now I installed the ones named with windows(just by double clicking 'em & storing in my C/: drive) & placed the last .zip ( jai-1 1 1-lib.zip) in the lib folder of the sketchbook.
Now when I ran the applet with-out a projector I see a white screen just & nothing else & it shows some kind of error.

Hi ;
I recently tried to extract some of my processing applets . It's getting extracted but when I double click on the .jar file, it shows run-time error. I've downloaded & installed recent java also, but no effect.

I'am still using version 1.5.1 as I've installed many libraries in it & is too lazy to copy 'em to the new one.

Some body faced the same problem? Please help
