Well Bruno,

now it is everything clearest, nevertheless I stay with some doubts...

for what you said, better should be to utilize DEM file directly in FICTION EDITOR - utilizing IMAGE MAP NODE - applying it a procedural terrain.

But the DEM file nust be a HQ DEM file , as 1 arc second or better 1/3 arc second (30mt or 10mt).

If you HAVE NOT this HQ DEM files (as far as I know, just USGS file are avaiable in this quality...) you can try to build a greymap scale 16 bit from a geo or topographic maps, or also from satellite screenshoot toke in Google Earth (o Google Maps).

Is that right?

Many thanks|

Hallo everybody,

it seems to understand that - maybe not best practise but good practise - is doesn't use DEM file but a Greyscale Map on procedural (also to have notmillions polygons...!): Procedural+Greyscale Map +... adding Mask with Brush ti define better terrain, and so on...

But if i Import a DEM file with Import Object than I  also can convert it in e procedural... and imporve quality... hard to understand the differences...

Many thx!

Quote - Best way to import a DEM file in Vue: Import object dialog. It will retain the original scale of the map. DRawback: low res

Best way to enhance a DEM in Vue: use a proc terrain and use the dem as your altitude production function, and add a fractal to blend with the dem. Drawback: accuracy of the terrain is lost, since the fractal adds procedural detail, DEM must be at least 16bit.

Sorry Bruno but something is strange for me.

I didn't understand if I have to import DEm directly (Import object dialog) or if I have to create a procedural, turn to Terrain Editor, smooth completely terrain and than use " the dem as your altitude production function..." as you suggested.

Can you please explain it?

Many thx!

And the best way to enhance a greyscal 16 bit map? Maybe use a standard terain, Edit Object/ Picture and import map from here and than convert terrain in procedural and edit it?

Many thanks!

Many thanks Bruno,

I'm going to try you suggestions! I hope we can still talk about this process.

Ciao!

Quote - 2- Load a procedural terrain, right click the preview sphere of the altitude production function on the riught of the terrain editor, and choose Edit.

Delete all present nodes, click on the Texture map icon on the left toolbar of the function editor, connect the new Projected texture map node to the altitude output. Next, load in the tiff file under the texture map preview, set the resampling to "bicubic" to avoid artifacts on the terrain.

Here I can't understand wht you mind. I'm here (see screenshot) but after I can't go forward... :(

which page?

Attachment... can't I make.

Here is the tutorial:

Many thanks, Bruno!

I'm testing both solutions but the big problems is to find a good DEM and, for MAc users, to trasform this DEM files, a a GEOtiff or in a DEM Ascii good to be import in VUE. For Win users ther's 3DEM that can generate a good DEM file but for the Actual Mac OS (Intel 64x) I didn't find a similar software like 3DEM for Mac. Grrrrr

I post a old .pdf which guide to make a very, very good terrain from DEM file to VUE.Maybe have you something to add... the tutorial is really old...

Old tutorial but super result!

Ciao!

Hi Bruno,

I can't make what you suggested at point 2: can you explain in detail, maybe with a screenshot what I've quotedfrom you, please?

Many,many thanks!

Bien, au revoir! Merci!

Hallo Bruno,

really many thanks! I'm going to try what you suggested and I'll replay  you if I've problems, okay?

About .tiff, im going to create that in photoshop in 16 bit or, maybe is bettere, in 32 bit. Non problems.

THX!

p.S. Are you italian?

Okay everybody, now are arriving two kind of files: a .dmt file and a .tiff file with a greyscale map of the geographical area I need.

I'd like to knownow  what I 've to do having a .DEM file, and having a .tiff file.

Which are the procedures to create a terrain in vue based to .dem file or base to a greyscale tiff image?

Any guide or tutorial?

MANY THX!

I don't have a map in a file but a normal paper map like a city map you can buy at the drugstore...

I would like to "transform" (by photo camera or scanning map...) this map  in a file good for Vue (.dem, tiff, geotiff and so on) ... but, repeat I don't have any file now . I didn't find a file DEM in internet and I didn't create these kind of file from a real map cause I don't know if I can create that; right now certanly I don't know how to make that.

Thanks!
