Hi, after getting mad with Lidar points colorizing which till now required a DB table with GRASSRGB attributes, I have modified d.vect to support colors directly from z height (geometry). Works for 3D points, lines (eg, 3D contours) and 3D polygons (eg delaunay triangles):
# Spearfish: g.region rast=elevation.10m r.random elevation.10m n=5000 vector=random3d -d d.mon x0 # display as black points d.vect random3d # display 3D points colorized according to z height d.vect -z random3d zcol=gyr # 3D contour lines r.contour elevation.10m out=contour20m step=20 d.vect -z contour20m zcol=gyr # generate 3D triangles v.delaunay random3d out=random3d_del # display 3D polygons colorized according to z height d.vect -z random3d_del type=area zcol=gyr Enjoy, Markus _______________________________________________ grass-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-dev
