Forgot to mention. As I moved and zoomed, the NVIZ scene became slower and slower. Eventually it crashed. With no vector overlaid, it is fast. I wonder if somehow vector lines are rendered as points now, with a lot of points for a long, irregular line like
a stream or contour line. Trying to render hundreds or thousands of points is slowing it down??

<div style="word-wrap:break-word" class="">One of my students recently install GRASS 7.0 svn for Windows. Today we tried to display a raster DEM in NVIZ, overlaid by a couple contour lines with values for walking distance from a site (from r.walk). The lines
displayed but are floating above the surface at about the level of their contour values (3600 and 7200), in spite of all my attempts to bring them down to earth.

<div class="">I wonder if this happens only when the line is draped over a surface, then it's drawn as many lines. I don't think there is a simple way to set line caps in openGL, so I doubt I could fix it.</div>

<div class="">does this happens with recent grass? I thought I fixed something similar to what you describe sometime in summer, but it might be a different problem. If it happens with recent GRASS, could you send me the data (or show the problem on nc_spm)?</div>

<div class="">I can do a ticket but perhaps these are already fixed in GRASS 7.1? I don’t use Windows regularly so I’m not up on what works and does not work.</div>
