Java games rock!


« Posted 2002-11-12 18:22:01 »

I am new to Java3D I am trying to read in a text File that contains x,y and z coordinates.  I want to put them into a point Array.  How do I get the points from the file so they are displayed on the scene.  This is what I tried.

   StringTokenizer st = new StringTokenizer(line);
               time = Double.valueOf(st.nextToken()).doubleValue();
               x = Double.valueOf(st.nextToken()).doubleValue();
               y = Double.valueOf(st.nextToken()).doubleValue();
               z = Double.valueOf(st.nextToken()).doubleValue();

                 PointArray par = new PointArray(vertexCount, vertexFormat);
                 Point3d[] pts1 = new Point3d[1];
                 pts1[0] = new Point3d(x,y,z);

                  Color3f[] co= {new Color3f(1.0f,0.0f,0.0f), new Color3f(1.0f,0.3f,0.5f),new Color3f(0.8f,0.3f,0.9f)};
                 par.setCoordinates(0,pts1);
                 par.setColors(0,co);

               //System.out.println(time+ ",  "+x);
                    this.addGeometry(par);

but it didn't work.  I would appreciate any assistance available.

for great justice!

This doesn't look bad to me, assuming you are incrementing the indices of pts[] rather than sending each new point3d to pts1[0].

What error message is it raising? As a start you could get the values output to the command line with a simple System.out.println("x= "+x+", y="+y+", z="+z) type command. That would at least tell you whether the tokens are being parsed correctly.

??

The code snippet just creates a single vertex? What do you expect to see then?
