Returning integer value

[3 Replies]

I Have a processing code which is talking to my arduino. I need to get the xCur, yCur, and zCur values into draw so i can make visuals that are corresponding with the movement of my accelerometer, this code works and gives me results, but not sure how to return them into draw? This project is due tomorrow, and I would love some help thanks soooo much....

Here is the original code...

import processing.serial.*;

Serial myPort;

int delim = (int)('!');

final int maxSize = 400;

int[] xValues = new int[maxSize];

int[] yValues = new int[maxSize];

int[] zValues = new int[maxSize];

int curIndex = 0;

/********************************************************************

Setup routine

********************************************************************/

public void setup() {



println(Serial.list());

myPort = new Serial(this, Serial.list()[0], 9600);

println("delimiter:" + delim);

frameRate(600);

background(0);

size(maxSize,700);

}

/********************************************************************

Draw routine

********************************************************************/

public void draw() {

fill(10,10,10,40);

rect(0,0,width,height);



//read data from the accelerometer

try{

readDataFromSensor();

}catch(Exception e){}



//start plotting the datasets

plotArray(0);

plotArray(1);

plotArray(2);



}

/********************************************************************

This routine reads data from sensor

********************************************************************/

void readDataFromSensor(){



//This if block manages the data from the accelerometer

if(myPort.available() > 0){

//read bytes from the port until the delimiter is found

String data = myPort.readStringUntil(delim);

if(data != null){

//grab the x,y,z accel values from the string that was just read

int xDelim = data.indexOf(",");

int xCur = Integer.parseInt(data.substring(0,xDelim));

int yDelim = data.lastIndexOf(",");

int yCur = Integer.parseInt(data.substring(xDelim+1,yDelim));

int zDelim = data.length()-1;

int zCur = Integer.parseInt(data.substring(yDelim+1,zDelim));

// println(xCur); println(yCur); println(zCur);

//add these values into the respective arrays

xValues[curIndex] = xCur/5;

yValues[curIndex] = yCur/5;

zValues[curIndex] = zCur/5;

//manage the index and see it doesn't overflow

curIndex++;

if(curIndex == maxSize) curIndex = 0;

}

} //end if block - sensor read



}

/********************************************************************

Plots the specified array

********************************************************************/

void plotArray(int index){



//based on the index, pick a dataset

int[] dataSet = null;

if (index == 0) {dataSet = xValues; stroke(255,255,0);}

else if(index == 1) {dataSet = yValues; stroke(0,255,255);}

else if(index == 2) {dataSet = zValues; stroke(255,0,255);}



//set the baseline for this set using index and draw it

int yBaseLine = ((height/3) * (index+1));

line(0,yBaseLine - 30,width,yBaseLine - 30);



//plot the dataset

for(int i = 1; i < curIndex; i++){

int xCo = i;

int yCo = yBaseLine - dataSet[i];

int xPrev = i - 1;

int yPrev = yBaseLine - dataSet[i-1];

line(xPrev,yPrev,xCo,yCo);

}

}

save in .mov or .mpeg files

I created an animation with an object, I want about the first 30 seconds of it to be saved as a .mov

the only other way I can think of is a screencasting software.

Any ways to export a certain amount of seconds of the animation to an .mov?

thanks,

Cyrus

Orbit 3D object around camera?

I cam trying to orbit a a 3D sphere around the camera, I want the camera to be fixed.

Another way I guess I could also rotate the camera around itself and have the object to stay fixed to achieve the same effect, either way would work fine.

I am new to processing, so any suggestions would be great.

Thanks

Cyrus
