##### Half-Height Map Color Scale
« on: March 04, 2016, 01:50:29 PM »
Hello all,

On the Simutrans maps page under creating maps (or whatever it's called...), they have a tutorial which gives out grey scale values for shading the map for conversion to .ppm then going into Simutrans. That scale is set up for the old double height system of terrain that has been superseded by the half-height version from I think version 120.0.0 (right/wrong?) and onward. I was curious if somebody already has figured a new scale taking half-height into consideration? If not, I'll give it a go in my spare time and post the findings here once I get them.

Thanks!

The maps are still read in the same way. It's just that now you can connect two height tiles difference with each other by means of a normal slope.

So the maps in half-heights are half their original height when loaded from the same image compared to old/full-height.

I've been playing with heightfileds maps to create color palette for half-height. The grey scale at tutorial at simutrans maps will give you map with two half-height steps for every color. ( It's even a little bit bugged - it create double jump (4 half height slopes) between: R=203 G=203 B=203 andR=213 G=213 B=213

-Simutrans from heightmap create map raging from -19 to 20 (if you set water level to -20 at the map settings.) This is probably intended to leave you some levels (-32 to 32) for your infrastructure?
-So, I tried my own greyscale going down by 5 points (to be easy). 255,255,255 – 250,250,250 – - etc . It works well. It'll give you lvl 20 at 255,255,255 paint, lowest dry ground at 45,45,45 and an additional 5 sea levels.

255,255,255

I tried use greyscale below and Some 5 points steps create two half-height steps. So, I add following color to greyscale and I have 1 half-height step for each color:
237,237,237
217,217,217
197,197,197
177,177,177
157,157,157
137,137,137
117,117,117
97,97,97
77,77,77

255,255,255 gives level 30 and grey 135,135,135 gives level 0. I tried greyscale onle to 75,75,75 which means level -15.
