Generated by the following section of code:
if (floor[numButton] == true) {
Point3f[] pts2 = new Point3f[4];
pts2[0] = gridPoints[(numButton + j)];
pts2[1] = gridPoints[(numButton + j + 1)];;
pts2[2] = gridPoints[(numButton + j + detail + 1)];;
pts2[3] = gridPoints[(numButton + j + detail + 2)];;
int[] indices2 = {
0,1,3,2
};
GeometryInfo gi = new GeometryInfo(GeometryInfo.QUAD_ARRAY);
gi.setCoordinates(pts2);
gi.setCoordinateIndices(indices2);
System.out.println("GETTING HERE");
floorShape[floorNum] = new Shape3D();
floorShape[floorNum].setGeometry(gi.getGeometryArray());
PolygonAttributes poly = new PolygonAttributes();
poly.setPolygonMode(PolygonAttributes.POLYGON_FILL);
poly.setCullFace(PolygonAttributes.CULL_NONE);
Appearance appear = new Appearance();
ColoringAttributes redColoring = new ColoringAttributes(green,
ColoringAttributes.SHADE_FLAT);
appear.setPolygonAttributes(poly);
appear.setColoringAttributes(redColoring);
floorShape[floorNum].setAppearance(appear);
floorGroup[numButton].addChild(floorShape[floorNum]);
}
Can anyone tell me what I am doing wrong...a very similar piece of code
works fine elsewhere in the program! The references to the gridPoints
array locations are valid, that is not the problem. Any help would be
much appreciated!
