<div dir="ltr">Looks fine to me except that you can yank the vertexglyph as it is not doing anything for you. The polydata can go directly into the mapper. Maybe your points have a really large values and you are running into floating point issues. Look at the bounds on your points. Could be something else but the basic code looks OK to me.</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Mar 14, 2017 at 9:11 AM, afnanahmad <span dir="ltr"><<a href="mailto:afnanahmad@live.com" target="_blank">afnanahmad@live.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Here is the code I'm using, not sure which step is wrong.<br>

for some of the files this code is working fine.<br>
