Hi Ashish<br><br>give the condition that the cross product should be greater than zero. I guess it will resolve the problem.<br><br>Ashish Garg<br><br><div class="gmail_quote">On Wed, May 2, 2012 at 12:38 PM, Negi, Ashish <span dir="ltr"><<a href="mailto:ashish.negi@honeywell.com" target="_blank">ashish.negi@honeywell.com</a>></span> wrote:<br>
