TGA export problems

[4 Replies]

Hi!

I'm trying to export TGA files by simply having this at the end of the draw() loop:
1. saveFrame("output/seq-#######.tga");
Unfortunately all of the exported files have glitches. Is this a know issue?

It is not possible for me to export tiff or jpg because it would require way to much disk space...

Animation points from array

Hi!

I have a question about animating points from an array.

Somehow I can't figure out how to make this work.

Please see below an excerpt from my code.

I have a csv file with the data. It's is parsed in the class placesIveBeenV (see code at the bottom).

In setup() the csv is loaded and in draw() the dots + lines are drawn.

But how can I animate these dots + connecting lines?

I tried a couple of different things but nothing works.

Any help is greatly appreciated!

Thanks!
1. void setup() {
  
  size(580, 800);
  
  smooth();
  
  noStroke();
  
  // VIN
  
  String[] NYlocationsV = loadStrings("openpaths.csv");
  
  locationsV = new placesIveBeenV[NYlocationsV.length];
  
  for (int i = 0; i < NYlocationsV.length; i++) {
  
  locationsV[i] = new placesIveBeenV(NYlocationsV[i]);
  
  }
  
  }
  
  void draw() {
  
  if (savePDF) {
  
  beginRecord(PDF, "NYmap"+y+"."+M+"."+d+"-"+hr+"."+m+"."+sec+".pdf");
  
  }
  
  background(245, 245, 245);
  
  // DRAWING VIN
  
  for (int i = 5; i < locationsV.length -1; i++) {
  
  noStroke();
  
  fill(vin);
  
  ellipse(locationsV[i].x, locationsV[i].y, dotSize, dotSize); // DOTS
  
  stroke(vin);
  
  strokeWeight(routeLine);
  
  line(locationsV[i].x, locationsV[i].y, locationsV[i+1].x, locationsV[i+1].y);
  
  }
  
  }
  
  //and the class:
  
  class placesIveBeenV {
  
  float x, y;
  
  float X, Y, Z;
  
  String lat; // y
  
  String lon; // x
  
  placesIveBeenV(String s) {
  
  int pos = s.indexOf(',');
  
  lat = s.substring(0, pos);// LAT
  
  s = s.substring(pos+1);
  
  pos = s.indexOf(',');
  
  lon = s.substring(0, pos);// LON
  
  s = s.substring(pos+1);
  
  pos = s.indexOf(',');
  
  String al = s.substring(0, pos);// ALT
  
  String date = s.substring(pos+1);// DATE
  
  X = float(lon);
  
  Y = float(lat);
  
  Z = int(al);
  
  x = map(X, -73.891000, -74.035000, width,0);// MIN, MAX, MAX, MIN
  
  y = map(Y, 40.660000, 40.810000, height,0); // MIN, MAX, MAX, MIN
  
  }
  
  }
