I'd like to announce a new library that I've been working on called libxd. It's written from scratch in C++ and has a very similar API like Processing or p5.js. libxd is available for all major operating systems and is well documented (see for yourself). It should be fairly simple to get started and write your first sketches. Prior knowledge of C++ is useful but not mandatory. Bare in mind, libxd currently only supports 2D graphics but being OpenGL-based it could potentially be extended to 3D in the future (hence the name libxd, I know probably noone will get it :p). Most of the essential features of Processing and p5.js are also available for libxd, but I guess there is a lot of room for improvement!

This announcement should not only be addressed to end users but also to experienced C++ developers interested in getting involved in the development of libxd. Being a Java web developer myself, I'm kind of a rookie when it comes to C++, so feel free to leave some feedback or open a pull-request, I'd really appreciate it :)

libxd is Open Source and has been published on GitHub under LGPL 2.1.

Links that could be of interest:

• libxd on GitHub pages
• libxd GitHub repo
• SpaceInvaders made with libxd

Happy coding!

I've been working on my C++ library for processing for quite a while now and I've also started working on my own IDE, but I changed my mind because I wasn't able to make it multiplatform. Let's leave that... So, I decided that I'd at least try to submit my library as a new mode. It has many basic functions and it's just basically based on C++. It's probably not as optimised as it should be, but I'm making it as a school assignment.

So this is just my 5 cents, take it or leave it, if you take it, I'll let my IDE rest in peace.

Yours sincerely,

Here is a link to my library with list of all working functions.

I'm currently doing a visualization of motion in the design project that I'm in.

I'm trying to use 'ZED' which is a 3D Camera for Depth Sensing by stereolabs. co.

But it's developed based on C++, So it seems like it won't work with the Processing. If I make a C++ codes for running the camera is it possible to do memory mapping with Processing? Or is it better to implement a wrapper?

thanks!

I'm building a prototype for an https://arduboy.com/ game A video of what's playable so far can be seen here:

I'm developing the prototype using Processing. I was wondering if a good soul would help me translate my code to C++ which is what's needed to compile for Arduboy. It will be distributed for free, and open sourced. I'll provide the fully functional Processing code. No money involved, but the opportunity to get coding credit on hopefully a fun little game on a fun little device.

Some images of the game:

 The first parking (B- biggest parking area), can accommodate 15 cars in a column

 The second parking (M- middle parking area), can accommodate 10 cars in a column

 The first parking (S- smallest parking area), can accommodate 5 cars in each column

 The first row in each parking is reserved for the faculty and staff

 Each parking has the same number of rows per column

 To park you should specify the parking area as B, M, or S and the parking time. The system will check for the availability. If a parking slot is available the system will allow the user to park his car. If not, the system will redirect the user to another parking. If no parking slot is available at the three parkings the system will ask the user if he would like to park in a column reserved for cars that leave at a later time. The user may not choose to park at a time earlier than the one he/she specified at the beginning.

 The system should provide the following information about the three parkings:

 The total number of parked cars at a specific hour

 The number of parked cars in each parking

 The number of available parking slots

 View the three parking area.

 The number of rejected parking request

Is it possible to call from c++ a module of processing. I mean I would have a menu in c++ call something from processing and get back to it, perphaps returning some data from it

Looking forward comments

double sum(cv::Mat img, int startedX, int startedY, int w) {
  double res = 0;
  std::cout << "startedX= " << startedX << "/ startedY= " << startedY <<  std::endl; 
  for (int i = startedX - ((w - 1) / 2); i < startedX + ((w + 1) / 2); i++) {
    std::cout << "i= " << i <<  std::endl;    
    for (int j = startedY - ((w - 1) / 2) ; j < startedY + ((w + 1) / 2); j++) {
      std::cout << " j= " << j <<  std::endl;
      if ((i >= 0 && i < img.size().width) && (j >= 0  && j < img.size().height)) {      
        res += img.at<float>(i,j);
      }
    }
  }
  return res;
}

This is a portion of my main function where the program crashes :

for (int k = 0; k < imgSource.size().width; k++) {
  for (int l = 0; l < imgSource.size().height; l++) {
    if( (k >= 0 && k < imgSource.size().width) && (l >= 0  && l < imgSource.size().height) ) {
      std::cout << "k= " << k <<"  l= " << l << " wmax= " << wmax << std::endl; 
      newImgMax.at<float>(k,l) =(float)sum(imgMax, k, l, wmax) / (wmax * wmax);
    }
  }
}

for k=0 and l=0 the program works fine and returns a value but for k=0 and l=1 the call of the function(sum(imgMax,0,1,1)) doesn't pass,it crashes and shows a segmentation fault core dumped.This is my output:

k= 0  l= 0 wmax= 1
startedX= 0/ startedY= 0
i= 0
j= 0
k= 0  l= 1 wmax= 1
Segmentation fault (core dumped)

Cat myCat = new Cat()

Means make a new object, from the class Cat, which can be accesed by the name myCat.

Making a new object of the class Cat, means allocating memory to store all the variables in the class Cat, the location of this data, (its adress) is then stored at the variable myCat. At some point, the object cat, won't be used anymore (at the latest when the program is terminated), then the allocated memory must be freed, but you can't write in the code when, and how you want to do that.

In the programming language C++ , you will have to use the keyword delete (or delete[]) to delete each of the objects you initialized using new. In C++ you also get to make a destructer-function when you make a class.

In processing you can't delete objects manually, so i asume, it happens automatically, but i would like to know how it works. And what about objects stored in other objects, or if more objects of the same or different class, are storring the same other object in them?

and are there a way to manually delete objects?

String keyPressed() { if (key == '\n' ) { saved = typing; typing = ""; } else { typing = typing + key; } return saved; }

I'd like to use some C++ libraries in a Processing project but I am not sure how to do it (I am completely newbie in Processing and Java).

The way I proceeded is by using SWIG to create a shared library (.so) that can be then loaded (using the System.load command) in a Java application in the same way as explained in the tutorial:

http://www.swig.org/tutorial.html

This might be a super basic question, but my doubt is (I have not been able to find a solution in Google or Stackoverflow) how do I import this library into Processing?

Using the example provided in the link, neither:

System.load("/path/to/example.so") # I compiled the library with .so rather than .dll, I am using Mac OS X

nor

System.loadLibrary("example") # Putting the example.so file in the library folder

seem to actually import the library. When I try to do something like:

double var = example.fact(5); 

Processing complains saying that "Cannot find anything named example". Could you help me with this? Any hint on how to import .so libraries in Processing would be greatly appreciated.

Many thanks!

I exported my Processing project, which renders as P3d, successfully. The .exe file works, even from the command line. I need to run this executable from a c++ program. When I call system("Project_name.exe") on it, it doesn't open up the file. I checked the path by opening other types of files like .txt successfully. I also tried it with system("start Project_name.exe")and it gives the same input.

Is it because its not reading java with the app properly? The java folder is also in the same directory. Please help!

Note: I understand system calls are not the best approach. I also used CreateProcess but was not successful. I think the file is opened but the frame and contents doesn't display.

Thank you

I have a Processing program that takes care of some image processing work once the pictures are taken. However the sdk for the camera is in c++. Ideally, I would like to call Processing functions from my c++ program. But a workaround is also to call the Processing program to run once the pictures are taken, automatically from c++.

Can I please get some guidance on how to do this? One possible approach might be to turn Processing project into a jar file and call it from the c++ program to run. Is this doable?

Thanks in advance

The specific error I'm getting is:

A library relies on native code that's not available. Or only works properly when the sketch is run as a 32-bit application

My library loads our internal dylib using JNI:

public class LibGForProcessing { static { System.loadLibrary("LibG"); } ... }

To be used in a Processing sketch as follows:

import autodesk.libg.*; LibGForProcessing l = new LibGForProcessing(this); void setup() { size(400, 400); Point p = Point.by_coordinates(0, 0, 0); } void draw() { background(0); }

I've verified that I can run the library on command line java (Java HotSpot(TM) 64-Bit Server VM) with the following script:

import autodesk.libg.*; class LibGJavaTest { static { System.loadLibrary("LibG"); } public static void main(String[] args) { LibG.start_asm_library(); Point p1 = Point.by_coordinates(0, 0, 0); Point p2 = Point.by_coordinates(10, 10, 0); Line line = Line.by_start_point_end_point(p1, p2); double d = line.length(); System.out.println("d is " + d); LibG.end_asm_library(); } }

A have a feeling that the problem lies with OS X not being able to find one of the dependencies of the library, of which there are many. Here's the otool output for the dylib I load with JNI:

I've created a bin directory inside of the lib directory of the library folder, containing both libdsnetwork.dylib and libgcore.dylib

Could anyone on the forum help with the following questions:

• Is there any way to set the @rpath for this Processing library?
• Where does JNI look for libraries when it's invoked inside of Processing? Does ./bin resolve to the lib folder of the library folder, or is it somewhere in the main Processing.app folder?
• Is there any way to get a more detailed output from Processing to see which library it's failing to load? I've run Processing inside of dtruss and I can't see any calls to load a library.

I have a set of gaze tracking glasses which using an SDK in C++. It gives x and y data to where you are looking. I'm wondering how I could use that data to navigate a computer screen. Basic controls like zooming or scrolling and how to integrate the C++ programme into processing
