As I move the model around in 3d with the mouse, I'd like the shadow to remain perpendicular to the arrows, similar to how it would look if I walked around the cylinder on a sunny day (assuming I didn't walk extremely slowly). I'd like the light source to be fixed relative to ground rather than the screen - I'm surprised that isn't the default or an option (at least I haven't found it).<br><br></div>Thanks, Bob <br><br></div>ParaView 5.2 on Windows 7<br></div><div class="gmail_extra"><br><div class="gmail_quote"><span>On 6 January 2017 at 00:17, Scott, W Alan <span dir="ltr"><<a href="mailto:wascott@sandia.gov" target="_blank">wascott@sandia.gov</a>></span> wrote:<br></span><div><div class="m_-7911432899513791434h5"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
