This is my first post. smile.gif

FYI.
Over the last couple of weeks there have been 2 new Blender add-ons to import DTMs/DEMs.

The first, written by Tim Spriggs from HiRise, imports HiRise DTMs into Blender.
The add-on is now part of the Blender 2.56a Beta release and is available at:
Download Page
The Blender Wiki page for the add-on.

I am a beginner with Blender but here are 2 of my attempts with the add-on.
I am using an XP Pro box with 2GB of ram.
I am still working on the colors and lighting.
Zumba Crater
Victoria Crater

The second add-on, written by Valter Battioli, imports LRO Lola and MGS Mola data.
This add-on is still in development.
BlemderArtist.org thread.
The Blender Wiki page for the add-on.

I just started playing with this one.

Hmm - can you export a mesh derived from HiRISE DTMs?
DaveRM
It would depend on the format.
What format do you need?

I have not tried to export anything. No place else to go. smile.gif

the new version is finally getting plugins
I have been using the old "load_dem.py" &"MoonAndMars.py" in 2.49b

now i need to see if 2.56 opens .ply meshes 2.5 did not
then if i can export to .cmod
MouseOnMars
Can this cope with Mars Express DTM's ?
JohnVV
DaveRM
and any other

i can make available a 65536x32768 16 bit unsinged map derived from the lola 256 that has been "destripped " full map
it is however 2.1 gig zip file and currently in MY default format ( vips/Nip2 *.v format)
the first post on
"http://blenderartists.org/forum/showthread.php?t=205737"
"Tycho crater on the Moon"
has a very stripped mesh
JohnVV
been having "fun" with io_import_LRO_Lola_MGS_Mola_img.py
it opens the LDEM_?.IMG + LDEM_?.LBL just fine
BUT
any that i export to img from isis " isis2pds " ( even /isis_3/data/base/dems ulcn2005_lpo_0004.cub ,LRO_LOLA_LDEM_global_128ppd_20100915.cub ,molaMarsPlanetaryRadius0004.cub )
or the lola 64k map i made ( reduced to a 2k map )
or the "PhobosShapeNew.cub" shape model i made

they all crash 2.56

time to fined the old username/pasword for blenderartists.org or make a new one
JohnVV
crashing solved
the blender linux 64 bit binary is unstable on suse 11.3
i had to build the svn source

ALSO if there is a vicar header on the img file there might be a crash
the ldem4,16,64,256, do NOT have a header in the img .
Only the detached lbl .

so if anyone exports isis cub's to img REMOVE the pds header in the img
JohnVV
an update
the tool by ValterVB works fine on the current Blender 2.5.8
io_import_LRO_Lola_MGS_Mola_img.py
http://wiki.blender.org/index.php/Extensio...SA_IMG_Importer

at least on suse11.3 64 bit.
