HI,


Imagine that I'm doing a processing Sketch, working with some lines, creating a visual like this :














then i have the idea to video project my Sketch to a real object, lets say a polygon object ( i want only to project over the object and not have a 4:3 image) so I'll do a mask like this :















and then, i will use only the white parts of my mask to reveal the Sketch, and I'll have a video projection like this:
















i know how to do this with differents softwares, but how to do it within a processing Sketch?
Can someone ever try to do mapping projections with processing?
Can someone guide me to some code?

thanks,

Rodrigo

Hi there,


i'm trying to re-use and old sketch i used two years ago, but it's seems that's the SQlibrary has changed, "the constructor" is not working the same way that did before, when i try to create an instance:
msql         = new MySQL( Hostname+":"+Port, Database, Username, Password, this.parent );

the library tells me that's is undefined.
     
Can someone help me please?

thanks!


here is my class:

1. // ---------------------------------------------------------
   // class SMSManager
   //
   // grabs messages from a database
   // ---------------------------------------------------------
   class SMSManager  implements Runnable
   {
     // Applet parent
     PApplet parent;
   
     // SQL
     MySQL msql;
   
     // Thread
     Thread grabThread;
     int    wait;
   
     // Last Id
     String    lastMessageIdFile="lastSessionMessageId.txt";
     int       lastMessageId;
   
     SMSManager(PApplet parent, int wait)
     {
       this.parent         = parent;
       this.wait           = wait * 1000;
       this.lastMessageId  = -1;
     }
   
     void start()
     {
       try
       {
         String lines[] = loadStrings(lastMessageIdFile);     
         if (lines.length>0)
           this.lastMessageId = int(lines[0]);
       }
       catch(Exception e){
       }

3. ///////THE PROBLEM WITH THE CONSTRUCTOR//////
4. 
       msql         = new MySQL( Hostname+":"+Port, Database, Username, Password, this.parent );

       grabThread.start();
     }
   
     void run()
     {
       if (Thread.currentThread() == this.grabThread)
       {

Hi,

i want to make a sketch that calls my webcam and saves an image by clicking the mouse and then put it in a mysql database, i did a simple sketch to take picture by clicking my mouse, but i'm really newbie for database.
I found the SQLibrary to connect my processing to the data base.
Can someone please guide me to which approach i have to take to do this well?
I'm learning some basic steps of MYSQL and i saw that i have to send a BLOB value to the datebase for the images, but how to do it exactly?
do i have to learn php?
do you know some tutorials to do this?


here is my simple sketch until now :

1. import processing.video.*;
   Capture cam;   
   
   int x = 0;
   int i = 0;
   
   void setup() {
     size(640, 480);
   
     cam = new Capture(this, 320, 240);
   
   }
   
   
   void draw()
   {
       if (cam.available() == true) {
       cam.read();
       image(cam, 160, 100);
      
     }
     
   }
   
   
   void mousePressed() {
    
     save("image"+i+".jpg");
     i= i+1;
   }

i know it's not a easy question to answer but any help will be very appreciated,
thanks,

Rodrigo

Hi!

i want to make a processing sketch that opens my "Skype.app" and the call me,  i used "open()" function to do it but i don't how to pass the command lines
Does anyone have tryed this?

1. 
   void setup() {
     size(200, 200);
   }
   
   void draw() {
     // draw() must be present for mousePressed() to work
   }
   
   void mousePressed() {
     String[] params = { "/Applications/Skype.app"};
     open(params);
   }
   

i found this for Windows:

/nosplash - do not display splash screen when Skype starts
/minimized - Skype is minimized to system tray when it starts
/callto:nameornumber - call the specified Skype Name or SkypeOut number
/shutdown - close Skype /secondary - allows you to start an additional skype.exe instance


thanks,

Rodrigo
