When generating a 3D box, build with floor, walls and a ceiling i get
sometimes the following error:
java.lang.ArrayIndexOutOfBoundsException
at com.sun.j3d.utils.geometry.Desperate.foundSplit(Desperate.java:316)
at com.sun.j3d.utils.geometry.Desperate.existsSplit(Desperate.java:241)

at jcmodel.parts_v2.JCRuimte3D.polyBox(JCRuimte3D.java:115)
It happend in the code in the line "tr.triangulate(gi)" aftre the
inialization of the Triangulator class
/*
* shaping the floor
*/
nr = grondvlak.npoints ;
Coords = new Point3f[nr];
for(int i = 0; i < nr; i++)
Coords[i] = new Point3f((float)grondvlak.xpoints[i]/1000.0f
,hoogte/1000.0f,
(float)grondvlak.ypoints[i]/1000.0f);
coordinateIndices = new int[1];
coordinateIndices[0] = nr;
int[] contourCounts = new int[1];
contourCounts[0] = coordinateIndices.length;
GeometryInfo gi = new GeometryInfo(GeometryInfo.POLYGON_ARRAY);
gi.setCoordinates( Coords );
gi.setStripCounts( coordinateIndices );
gi.setContourCounts( contourCounts);
Triangulator tr = new Triangulator();
tr.triangulate(gi);
NormalGenerator ng = new NormalGenerator();
ng.generateNormals( gi );
Stripifier st = new Stripifier();
st.stripify( gi );
vormpje = new Shape3D(gi.getGeometryArray(),
createAppearance(objColor));
vormpje.setCapability(Geometry.ALLOW_INTERSECT);
totalShape .addChild( vormpje );
My question is what is going wrong and how can i correct its:
with regards
