Hi everyone,

I am a new user of jzy3d and I am trying to run ScatterDemo.java in Eclipse.

But I always cope with this problem:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: Index -1 out of bounds for length 1

Any tips on how to solve it?

May you send us the stacktrace and copy the program you are running ?

Thanks

Dear

Jaime Souza

this error means that your array is empty.

Make sure to run all dependent classes in the DOC and demos

This is code:

package plot3d;

import java.util.Random;

import org.jzy3d.analysis.AbstractAnalysis;

import org.jzy3d.analysis.AnalysisLauncher;

import org.jzy3d.chart.factories.AWTChartComponentFactory;

import org.jzy3d.colors.Color;

import org.jzy3d.maths.Coord3d;

import org.jzy3d.plot3d.primitives.Scatter;

import org.jzy3d.plot3d.rendering.canvas.Quality;

public class Plot3DExample extends AbstractAnalysis{

public static void main(String[] args) throws Exception {

AnalysisLauncher.open(new Plot3DExample());

}

public void init(){

int size = 500000;

float x;

float y;

float z;

float a;

Coord3d[] points = new Coord3d[size];

Color[] colors = new Color[size];

Random r = new Random();

r.setSeed(0);

for(int i=0; i<size; i++){

x = r.nextFloat() - 0.5f;

y = r.nextFloat() - 0.5f;

z = r.nextFloat() - 0.5f;

points[i] = new Coord3d(x, y, z);

a = 0.25f;

colors[i] = new Color(x, y, z, a);

}

Scatter scatter = new Scatter(points, colors);

chart = AWTChartComponentFactory.chart(Quality.Advanced, "newt");

chart.getScene().add(scatter);

}

And this is the stacktrace:

------------------------------------

Rotate : Left click and drag mouse

Scale : Roll mouse wheel

Z Shift : Right click and drag mouse

Animate : Double left click

Screenshot : Press 's'

I have checked and my arrays are not empty.

This seams related to newt - a JOGL windowing toolkit.

I suggest you switch to version 2.0 of jzy3d (see tutorial folder in the github repo). Then if you still have problem with newt charts then use awt or EmulGL.

The surface and scatter exemple in 2.0 show more conveniently how to use these various windowing toolkits.

Thank you for the answers.

I am already using version 2.0 of jzy3d with the following dependencies:

<artifactId>jzy3d-native-jogl-awt</artifactId>
