| I had the idea to generate the terrain of a new map using SRTM data. I know that the terrain data is saved in the dem.png. So I'll have to program a converter, thats not the problem. For doing this, I need some more information about the data contained in the png-file. I tried to analyze the map01_dem.png. It seems that the red channel contains the height data and the green one something like a "smoothness factor". If I delete the green channel, I get a staged terrain. So my questions: 1. How do I have to interpret the range from 0-255 in the red channel? Is it the height in metres from the ground or just steps in an interval defined in any i3d-file (I didn't find a definition like this). 2. What kind of data is contained in the green channel? Is it interpretable as a gradient - or maybe just a simple decimal place? I would be pleased if someone could help. Best regards. |

| I've got it after some experimenting: The red channel contains the integer value and the green one contains the decimal place in steps of 1/256. Regards. |

| The data in the heightmap is a 16bit value, encoded in the red and green channel of the image. This means the final value can be calculated as: (red<<8) + green. The GIANTS Editor and the engine also support 16bit png images. For example you can create the in Photoshop by switching to grayscale and 16bits/channel. Maybe this is easier to edit. |

| The geological conditions, such as hills, mountains that I know to do it so I can mapba a new plant, river bed sand edit etc? Or even mapból X Y mapba to make the surface topography? I'm sorry but I can google translator to write in English so I apologize for the weird írásért. I can unfortunately only in Hungarian. : ( |
