Mesh terrain

[Graham Mills]

To make a low resolution mesh terrain of a real location together with an associated map texture:

• down load and install Maperitive (PC only) from http://maperitive.net/
• locate the place you want to map (make it region-size or thereabouts, i.e. not country-region or country-size)
• choose Tools|Export To 3D and save the COLLADA/dae file
• import to Sketchup (formerly Google, now Trimble -- I used v8; you will get errors -- just ignore them) and export in the same format
• upload the file to Kitely (I use Kokua so it's on Build|Upload|Model, making sure that you import textures (under the Upload Options tab)
• the mesh should appear in your inventory when upload is complete; you just need to rez it

The mesh will be large by default (that's the point!) and I take no responsibility for it borking your region so please backup your region first or use a temporary new one. The textures are cc-by-sa OpenStreetMap Project. They are low-res (as the example of the Great Orme at Llandudno shows) and I haven't played around with physics etc.

Just to warn you that there are texture alignment issues.

Wow thanks it is great

I use partial mesh terrain

Much easier to sculpt and terraform

Not so easy to texture blend here.

I haven't tried it (it's not available yet) but it looks like the upcoming Wolfram Language supports import and export of 3D file formats (.dxf, .obj that I could find) and may therefore render 3D terrains: http://www.wolfram.com/language/gallery ... ation-map/

I haven't tried the terrains yet but the basic creation and export of mesh works. No UV maps afaik https://programming.wolframcloud.com/app/
