point data form txt file
Nov 6th, 2007, 12:46pm  
hei there!

i'm trying to import particle data from a textfile.

looks like:

-0.372068,0.905460,0.388421
-0.368527,0.905460,0.380401
-0.398187,0.905460,0.379182
-0.320218,0.905460,0.364631
...
...
...

i want to place a point at all coordinates given! this is, what i'm doing now:

for (int i = 0; i< points.length; i++){
   Point[i] = new Point(int(random(-10, 10)), int(random(-10, 10)),
   int(random(-10, 10)), int(random(-140, 140)), int(random(-140, 140)),
   int(random(-140, 140)));

how can i integrate the txt.file? and check how many points there are?

thx for your help! mias

I'm making some assumptions about your point class here, I notice you've got 6 values, but I'm only providing 3 here, the x/y/z coords, you'll have to mess with thsi to fit it to your Point class.

Code:
String[] lines=loadStrings("myfile.txt");
Point[] points=new Point[lines.length];
for(int i=0;i<lines.length;i++)
{
  String[] coords=split(lines[i],",");
  Point[i]=new Point(float(coords[0]),float(coords[1]),float(coords[2]));
}
