Why is here error? Length of array is 3, but I can not read or write ...
SimpleVector[] positions = new SimpleVector[positionst.countTokens() / 3];
int positionsnumb = 0;
float x = Float.parseFloat(positionst.nextToken());
float y = Float.parseFloat(positionst.nextToken());
float z = Float.parseFloat(positionst.nextToken());
positions[positionsnumb].set(x, y, z);
