<div dir="ltr">Hi Bili,<div><br></div><div>My apologies for the long delay in replying to this thread. By now, I think you may be working with Trident. If things are working, that's great. However, Trident relies on much of the machinery that you were trying to use, so it's still possible that you see this error. The problem is likely related to how the LightRay generator is calculating the trajectory for the ray and not with the underlying ray machinery which it relies on. If it's possible for you to give me access to this dataset, I would be happy to take a look at this.</div><div><br></div><div>Britton</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Feb 15, 2016 at 9:30 PM, Nathan Goldbaum <span dir="ltr"><<a href="mailto:nathan12343@gmail.com" target="_blank">nathan12343@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">I think Cameron, Britton, and Devin have done this for their Trident project - you might want to contact them.</div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Feb 15, 2016 at 3:23 PM, Bili Dong - Gmail <span dir="ltr"><<a href="mailto:qobilidop@gmail.com" target="_blank">qobilidop@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Matt,<div><br></div><div>I've tried to construct the ray and ortho_ray objects, neither of which can reproduce the error.
