Subject: NVIZ: limitation regarding volume data

Platform: GNU/Linux/i386
grass obtained from: CVS
grass binary for platform: Compiled from Sources
GRASS Version: 6.1CVS

NVIZ currently features a limitation for the max number of volumes.
This limit is arbitrarily set to 100, there are apparently no such limitations
for surfaces, etc.

This causes strange effects and/or unexpected stops when scripting is used for
batch-processing of lots of data.

It is strongly suggested to increase the default value of the variable
MAX_VOL_FILES in /libogsf/gsds.c to a significantly higher value.

Thanks,
Peter

Looking at:

cd lib/ogsf

grep MAX_VO *
gsurf.h:#define MAX_VOLS       12
GVL2.c:static int Vol_ID[MAX_VOLS];
GVL2.c:    if (Next_vol < MAX_VOLS) {
gvl_file.c:#define MAX_VOL_SLICES         4
gvl_file.c:#define MAX_VOL_FILES        100

I feel that MAX_VOL_SLICES and MAX_VOL_FILES should probably go into
gsurf.h and that MAX_VOLS should match MAX_VOL_FILES.

?

Hi,

I have moved MAX_VOL_SLICES and MAX_VOL_FILES to gsurf.h.
The numbers are still unchanged (Helena or Jaro may recommend).
