Building a TriangleFanArray

Building 3D shapes Building a TriangleFanArray

Create lists of 3D coordinates and lighting normals for the vertices

Point3f[] myCoords = {
    new Point3f(  0.0f, 0.0f, 0.0f ),
    . . .
}
Vector3f[] myNormals = {
    new Vector3f(  0.0f, 1.0f, 0.0f ),
    . . .
}

Create a list of vertex fan lengths

int[] fanLengths = { 5, 6 };

Create a TriangleFanArray and set vertex coordinates and lighting normals

TriangleFanArray myFans = new TriangleFanArray(
    myCoords.length,
    GeometryArray.COORDINATES |
    GeometryArray.NORMALS,
    fanLengths );
myFans.setCoordinates( 0, myCoords );
myFans.setNormals( 0, myNormals );

Assemble the shape

Shape3D myShape = new Shape3D( myFans, myAppear );
