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>Related to this are a couple other NVIZ issues I’ve seen</div>
<div><br>
</div>
<div>1) making a line width greater than 1 creates a line made up of many many ++++ symbols at the size of the line width</div></div></blockquote><div><br></div><div>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><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">
<div>2) coloring a line only colors the first segment (cat=1) of a multisegment line.</div></div></blockquote><div><br></div><div>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><br></div><div>Anna</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">

</div>
<div>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>
