Welcome to the testTerrain application. The following
key commands and comand line parametrs listed in this
readme file will help get you started using the
dtTerrain API.

[w] moves the camera forward
[a] moves the camera to the left
[s] moves the camera backwards
[d] moves the camera to the right

[f] Super fly speed!
[g] Ground clamp the camera

/**************************************

proper usage

-c 

Sets the cache path used to store processed terrain
and terrain tile data. This is important for consequent
runs of the terrain to 're-use' existing processed
data.

-r 

This defines the resource path used for loading DTED,
model, or other resource data. For the testTerrain application
you need to specify the resource path to the dted data.

--dted 

It is required that you specify the DTED level, the 
latitude and the longitude of your terrain. This is required
to properly load, without it your application will exit 
quietly.

--geo 

This defines the path and filename to the geospecific
data used for the Vegetation Decorator. Without this specified
the GDAL will be unable to parse land classification data for
vegetation to be properly placed on the terrain.

--geodrape 

This specifies the image path for the terrain drape
decorator. The terrain drape decorator essentially paints the 
terrain.

--enable-vegetation 

This should be set to either 'true' or 'false'
depending on whether there is sufficient data and models to process
the placement of vegetation.

Example Usage

testTerrain -c "C:/terrain/cache" -r "C:/terrain/resources"
--dted 0 39 -121 --geo "C:/terrain/geotiff/CA_VEG_1.tif
--geodrape "C:/terrain/geodrape" --enable-vegetation "true"

Make sure you change the paths appropriately. If your paths are
correct the above will effectively execute the testTerrain application
with a DTED level 0 data located at 30, -121 with a draped image 
and vegetation.
