I've been playing around with the dtm.tga file. For the most part, it works very well. However, I am having a problem and I am not sure exactly how to fix it.
Basically, I cannot seem to get the same smooth ground on inclines as you would normally get in random gen. For each step in rgb value, there is a step in the terrain instead of a slope. The result is a very minecraft-looking world.
Does anybody know how smoother terrain is accomplished?
I suspect a couple things are possible.
One is that perhaps the dimensions of the dtm.tga image is different than the map size, and maybe the raw file is generated with floating point values in between each rgb integer value. I have no idea if this is the case because the game no longer provides this file.
Another possibility is that the tga is in a specific format that allows for floating point values, say in between rgb(100, 100, 100) and rgb(101, 101, 101).
Any clues?
