Using the Nmtools package

[tech2000]

What do you mean by "trash character"? Exactly what is it?

DOS format files always end with one or more Ctrl-Z (ASCII End-Of-File) characters and the remainder of that disk block should be filled with nulls.

Unfortunatly that doesn't do it since the trash character is a "" and that will break the ctx and ssc file.

Unfortunately, whatever character you tried to quote isn't showing up here. There is nothing between the quote symbols. You'll need include the hex (or octal or decimal) value of the character. You might try doing a hex dump of a short file and include that text.

[tech2000]

I have now fixed the problem and included a menu...

It can't be easier to use Fridgers nmtools now. The menu let the user chose between dxt5nm or PNG tiles. One keypress will result in a finnished directory that has to manually be moved to Celestia/extras.

Hope some of you will have any use for it.

Hi Anders,

GREAT! Many thanks for your efforts.

So now...perhaps...perhaps...Even Daniel wil become a happy owner of
a super-quality-monster-sized-incredibly-optimized NORMALMAP VT set

Cheers,
Fridger

It would be cool to add txtools to this too...


So Daniel, save the script to vtgen.bat and copy it to c:, install gzip, nvdxt (for dxt5nm tiles), nconvert (for PNG tiles) & nmtools. Be sure to have srtm_ramp2.world.86400x43200.bin.gz in c: and open a cli-promt.

c:>vtgen.bat

move directory c:\Earth to "c:\program files\celestia\extras" depending on your instalation...

[danielj]

Thanks,but I have to download all the file AGAIN.
Actually,what??s a cli-promt?

A DOS promt. CLI=Command Line Interface. I really don't know how to explain it any further.

Bye, Anders

[Fightspit]

A screenshot would be saying more than 1000 words

Here a "cli-promp"t or as know as "cmd":

[tech2000]

A screenshot would be saying more than 1000 words

Ofcourse it does, thank you..

Bye, Anders

[Fightspit]

I made in this topic (especially for danielj ) at third page a small "tutorial" for using the "cmd" .

Content:

In DOS, to change directory is :

Code: Select all

cd yourfolder

Exemple: you are at C:\Documents and Settings\User and you want go to My Document, you just type:

Code: Select all

cd "My Document"

Note: If your folder name has a space, you must put a "..."

Also, instead of doing several cd you can put a \ after your folder like this:

Code: Select all

cd "My Document\folder1\folder2\...\folder26" and so on...

And more, you can press several time on tab (tabulation) after typing cd to chose several folder that you can go to.

[danielj]

Ok,ok,but when can I download the file?
The NASA Arctic Server seem to be down...

It simply say that "vtgen.bat" is not a recognizable program.Neither is nmtools.
I have nmtools-1.0.1,DDS Utilities and XNView in C:\Program Files
The bin file is also in C:\Program Files.
What could be possible did wrong?

I didn??t have any vtgen.bat.I simply copied to Wordpad and named it vtgen.bat

srtm_ramp2.world.86400x43200.bin.gz
vtgen.bat

Open CLI promt and navigate yourself to c:\vtgen\ where you already have stored away the list of files..

c:\vtgen> vtgen

Or the easiest way of them all: navigate with windows explorer to c:/vtgen/vtgen.bat and double click it...

Best of luck... You can't fail this time.

Almost there,but there is something missing.In the vtgen folder,I have gzip.exe,nconvert.exe,nmstiles.exe,halfsize.exe,nms.exe,nvdxt.exe and the file "srtm_ramp2.world.86400x43200.bin".
Then,after I typed c:\program files\vtgen>vtgen,it appears the 2 choices:1.dxt5nm tiles and 2:PNG tiles

But immediatly after that,the prompt said that "the command choice is not an external or internal command,operational program or an archive in batches.The system cannot find the tag in the specified batch-answer 9009"

What??s wrong now?

"srtm_ramp2.world.86400x43200.bin"

I really hope you mean: srtm_ramp2.world.86400x43200.bin.gz

Bye.

[danielj]

NO,I mean .bin.
Oh,no.Maybe the problem is that I shouldn??t unzipped and because of this,the script went crazy?

"srtm_ramp2.world.86400x43200.bin"

I really hope you mean: srtm_ramp2.world.86400x43200.bin.gz

Bye.

[danielj]

I substitute the .bin file for the bin.gz,but the SAME answer 9009 showed up.
So,I think there are 2 possibilities:I copied the vtgen script in the wrong form or there is something wrong with my Windows XP prompt.If it is the latter case,there is nothing I can do at all...
