Anna,
<div class=""><br class="">
</div>
<div class="">I just tested on my Mac with GRASS 7.1 r61575.</div>
<div class=""><br class="">
</div>
<div class="">The color issue seems OK. All of a vector line is the same, selected color rather than just cat=1.</div>
<div class=""><br class="">
</div>
<div class="">The other issues are still there though:</div>
<div class=""><br class="">
</div>
<div class="">1. lines with width>1 look weird, almost as if they are composed of individual characters instead of lines. I’ve attached an image with line width set to 20.</div>
<div class="">2. I did an r.walk cost map and created contours at intervals of 3600 seconds (=1hr). The contours float far above the landscape, no inconsistent with a height = the contour value. I’ve attached images of NVIZ 3D and regular 2D for the same scene.</div>

<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="">Related to this are a couple other NVIZ issues I’ve seen</div>

<div class="">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 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="">2) coloring a line only colors the first segment (cat=1) of a multisegment line.</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>
