Display 3d position using acceleration

mascail

Hello people,

I want to move an object in P3D using live sensor data. The sensor outputs the current acceleration data (data-type float) for the x,y,z axes in m/s² every 0.1 seconds. Unfortunately I have no idea how to translate this data to work with processing and I haven't found any similar projects online. For any code ideas, pseudo code or tutorials I'd be very happy. Thank you

hello,

yeah, here is an example.

Instead of my keys you need to use your sensory data.

axes in m/s² every 0.1 seconds

so they can be positive and negative?

maybe it's enough to say :

translatex += sensorDataX;
translatey += sensorDataY;
translatez += sensorDataZ;

float rotationX;
float rotationY;
float rotationZ;

float translatex=300;
float translatey=300;
float translatez=300;

float z = 1.0;

int objectNumber = 0;


void setup() {

  size(1200, 900, P3D);
  background(0);

  sphereDetail(32);
}

void draw() {
  background(0);
  lights();

  pushMatrix();
  fill(255, 0, 0); // red
  translate(width/3, height/2, 0);
  translate(translatex-300, translatey-300, translatez-300);
  rotateZ(rotationZ);
  rotateY(rotationY);
  rotateX(rotationX);
  scale(z);

  if (objectNumber==0) {
    stroke(111);
    box(100);
  } else if (objectNumber==1) {
    rect(-33, -33, 66, 66);
  } else if (objectNumber==2) {
    noStroke();
    sphere(90);
  }

  popMatrix();

  fill(255); // white 
  text ("Use wasd and pl", 19, 19);
  keyPressed_ForContinuusKeyinput();
}

void keyPressed_ForContinuusKeyinput() {
  // apply sensor data here

  float speed = 3.9; 

  switch(key) {

  case 'a':
    translatex-=speed;
    break; 

  case 'd':
    translatex+=speed;
    break;

  case 'w':
    translatey-=speed;
    break; 

  case 's':
    translatey+=speed;
    break;

  case 'p':
    translatez-=speed;
    break; 

  case 'l':
    translatez+=speed;
    break;
  }
