That.

Can anyone help me?

public Vector3f[] getVertices(Node node) {
      Spatial spatial = (Spatial)node;
      if(spatial instanceof Geometry) {
         Geometry geometry = (Geometry)spatial;
         FloatBuffer vertexBuffer = geometry.getVertexBuffer();
         return BufferUtils.getVector3Array(vertexBuffer);
      }
      return null;
   }


or


public Vector3f[] getVertices(Node node) {
   return ((Spatial)node instanceof Geometry) ? BufferUtils.getVector3Array(((Geometry)((Spatial)node)).getVertexBuffer()) : null;
}
