if you don't want the command prompt visible use javaw instead of java.

#### Color Mapping (-colors)
You can change the default color of the polygons depending on their type in a color.properties file. The color notation in this file is a floating point value from 0 to 1 for each color channel rgb.
Example:
```properties
groundColor=0.9411765 0.9019608 0.54901963
roofColor=1 0 0
doorColor=1 0.784313 0
windowColor=0.0 0.5019608 0.5019608
wallColor=1 1 1
bridgeColor=1 0.49803922 0.3137255
landColor=0.64705884 0.16470589 0.16470589
transportationColor=1 1 0
vegetationColor=0.5647059 0.93333334 0.5647059
waterColor=0.5294118 0.80784315 0.98039216
```
#### Polygon Color Mapping (-mapping)
You can specify the color of a specific polygon via its gml:id and a color. The color here is for each rgb channel a value between 0 and 255
Example that would color a polygon in blue:
```
# polygonName, red (0 - 255), green (0 - 255), blue (0 - 255)
PolyIDGeo22796924,0,0,255
```
## Known Problems
* The color is not set correctly when the geometry of a surface is in the solid and the boundary surface is only referencing it.
* The two configuration file use different color formats
