In centroid_zoomed_out, I basically create a line
using the line source filter, then using a programmable filter I compute its centroid and create a vertex. When I render both pieces of polydata, the result looks correct when one is zoomed
out.<br></div><div id="yiv672646329yui_3_2_0_17_1318435537670174"><br></div><div id="yiv672646329yui_3_2_0_17_1318435537670175">But zoomed-in (centroid_zoomed_in), it appears to be disconnected from the line. Is there any reason for this? I have never rendered points and lines together in paraview, but I would expect them to exist around the same origin.<br></div><div id="yiv672646329yui_3_2_0_17_1318435537670206"><br></div><div id="yiv672646329yui_3_2_0_17_1318435537670207">Thanks, Sohail</div></div></div></div></div></body></html>
