What is actually the trick for setting the right values for the 'section'
variable in a .hif file? The rad-file which I use contains a laser scan of a
real room and I have no idea what are the right values for the 'section'
variable. Every time I change the values the actual grid appears somewhere in
the middle of the whole scenery and I get such warnings as
dev/ogl.hdi: no sections visible from this view
if I try to turn around or to zoom. I understand why these warnings come, but I
would like to know how I can estimate the values for the section to avoid the
warnings and to be able to see the whole room and not only 2 walls.
Another funny thing is that the whole room stands on its side, i.e. lines that
are supposed to be vertical appear horizontal. First I thought the view
direction might be wrong, but if I run the same .oct-file with rview using the
same view-file everything is perfect. In addition to the right view direction
the rview-command produces colored images and rholo gives only grey values from
the same .oct-file. Is there a particular reason for such different results?
You want to align your model with the coordinate axis, and create a section grid that corresponds to a volume of free movement inside your space. How you figure out these coordinates is up to you -- I might recommend trying rview with the "trace" command to determine the locations of various scanned surfaces.
