Sean/ Daniel,
I have made a new 'g-voxel.c' that can output a file voxels.txt which gives
the percentage fill of all the voxels by region-- that is,
coordinates of voxel----total distance filled----percentage filll due to
each region.
For keeping track of the regions, i save the name using bu_vls_strgrab. Now
this program gives correct results.
However, since the name of the region was set many times, I made a function
which looks like this:
void setRegionName(struct bu_vls **vp, const char **nameSource, const char
**nameDestination) {
size_t newlen;
bu_vls_vlsinit(*vp);
newlen = strlen(*nameSource);
bu_vls_setlen(*vp,newlen);
(*vp)->vls_str = (char *)(*nameSource);
*nameDestination = bu_vls_strgrab(*vp);
}
[ basically the same set of commands was used even when I was doing it in
the hit callback function ]
however, I get an error saying:
"ERROR: bad pointer 0x82bfc30: s/b bu_vls(x89333bbb), was librt
seg(x98bcdef1), file /home/anurag/brlcad1506/src/libbu/vls.c, line 166
ERROR: bad pointer 0x82bfc30: s/b bu_vls(x89333bbb), was librt
seg(x98bcdef1), file /home/anurag/brlcad1506/src/libbu/vls.c, line 166
Saving stack trace to (BRL-CAD)-10720-bomb.log"
I do not understand why the same code inside the hit callback function does
not give the error, but when used as a function is giving this error.
Can you please help?
Thanks and regards,
