NVIZ 3D raster volume works ok if loaded with:
nviz -q
Panel->Raster volumes
Add, etc.
but locks up NVIZ while setting up the menus (panel->volumes).
I can trace it through the following: the problem seems to be in the
C -> Tcl transition after the C parts have done their thing and try to
return the result. It only seems to fail when result=TCL_ERROR (ie 1),
so maybe a symptom of some other corruption)
[nviz2.2_script]
Nv_mkPanelMenu
[vol.tcl]
mkvolPanel
create_isosurfs_subpanel
update_isosurfs_subpanel
set Nv_(ShadeStyle) [Nvol$curr isosurf get_drawmode]
[visualization/nviz/src/map_obj.c]
Nmap_obj_cmd()
isosurf()
[visualization/nviz/src/volume.c]
int isosurf_get_drawmode() {
[...]
else {
Tcl_SetResult(interp,
"Internal Error: unknown shade style returned in get_drawmode",
TCL_VOLATILE);
return (TCL_ERROR);
}
it locks when Nv_mkPanelMenu() returns a value of 1 to update_isosurfs_subpanel.
[src/map_obj.c MODIFIED]
...
else if (!strcmp(argv[1], "isosurf"))
{
int val;
val = isosurf(id, type, interp, argc, argv);
printf("==> val= %d\n", val);
fflush(stdout);
return (val);
}
shows that isosurf() worked ok.
