Hello t00fri! , firstly a very quick but grateful vote of applause for your sterling work building these tools. They are simply brilliant. helping bringing the massive and unweildly sci data into use for the lesser mortals with access to pc power only - hats off. - appologies if posting in wrong spot, i'm new here.
I have a question about the 85K strm data and how would be the best way to cut tiles out of it , keeping the full detail of the original map (or best 65K power of 2 if i have to) but to keep the output as a 16Bit png greyscale- instead of converting to a normal map, such as the nmtools are designed to do. I tried using your f-textools, but got strange errors in the resulting png... hoping there is a logical sequence of tools to pipe together to achieve what i want.?? :O) i want to use the map as a full mesh displace , rather than a bump, and so the height info is what i need.
thanks for your help,:o)
thanks for the applause...
The F-TexTools are made for 8bit not for 16bit!
So you just want to cut the original 16bit elevation map into tiles. Right? Well then you simply have to comment out the normalmap conversion in nmtiles.cpp, add some simple modifications in that loop (line 214 - 235) , skip the 16-> 8 bit conversion and recompile.
In detail there are a few more changes, of course, which are straightforward for a programmer however.
Then it also depends what output format you want for the tiles. Do you really need PNG? PGM format is much simpler to code in 2 byte.
Anyhow without knowing some C++, it's probably not so easy, but if you know how to code, its quite simple (still taking some time for checking etc).
