Hi everyone!
I'm experimenting a bit with augmented reality. I'm using my laptop's webcam but the quality is very low.
So I'm wondering what do I need for capture HD?
I was reading in some forums that say I should use GSVideo library.
But my question is about the hardware, what camera? What is the connection? video card?...
Thanks and happy new year!

Hi there! I have a question about how to save some images.
What I'm trying is that every time the user presses Ctrl + S to save the image processing save with name image-0001.png and then when the user presses again  Ctrl + S image-0002.png. How do I can do this?
I'm using the code below and what happens with this is that the image is saved with the number of the frame:

1. 
   boolean[] keys = new boolean[526];
   boolean checkKey(int k)
   {
     if (keys.length >= k) {
       return keys[k];
     }
     return false;
   }
   
   void keyPressed() {
   
     keys[keyCode] = true;
     println(KeyEvent.getKeyText(keyCode));
     if (checkKey(CONTROL) && checkKey(KeyEvent.VK_S)) {
       println("CTRL+S");
       saveFrame("Block_Mania-####.png");
     }
   }
   

Hi mates! I have a question about Excel or OpenOffice and their spreadsheets.
Is it possible to read information of the cells in spreadsheets with Processing?
Thanks!

Hi guys, I'm trying to import an obj object containing few Splines, for this I'm using the library OBJLoader. I thought It would work no problem but I can't see the Splines because I think processing is not loaded them.
Somebody know who loader Spline in processing?
Thanks.

1. import saito.objloader.*;
   
   OBJModel model ;
   
   float rotX, rotY;
   
   void setup()
   {
       size(400, 400, P3D);
   
       model = new OBJModel(this, "Box.obj", "absolute", POLYGON);
       model.enableDebug();
   
       model.scale(20);
       model.translateToCenter();
   
   
       stroke(90,200,225);
   }
   
   void draw()
   {
       background(56,56,56);
       lights();
       pushMatrix();
       translate(width/2, height/2, 0);
       rotateX(rotY);
       rotateY(rotX);
   
       model.draw();
   
       popMatrix();
   }
   void keyPressed()
   {
   
       if(key=='1')
           model.shapeMode(POINTS);
        if(key=='2')
           model.shapeMode(LINES);
        if(key=='3')
           model.shapeMode(POLYGON);
   }
   
   void mouseDragged()
   {
       rotX += (mouseX - pmouseX) * 0.01;
       rotY -= (mouseY - pmouseY) * 0.01;
   }
