VRTool 1.98b - released 19-nov-2011*** Status:
VORG 2011 basic compatibility (experimental version) *** Installation
1- If doing a new
installation, download from http://www.tecepe.com.br/nav/vrtool/setupVRTool.exe
Save and run (as administrator).
if you already have 1.97 installed, skip to step 2)
2- Download and save file: http://www.tecepe.com.br/nav/vrtool/vrtool.zip
extract files vrtool.exe and polaresVORG2011-leg1-classic.xml
to \program files\vrtool\
overwrite existing vrtool.exe
polaresVORG2011-leg1-classic.xml is a simplified version
of VORG 2011 polars, suitable for Weather Routing with vrtool.*** Import boat data from VORG 11
The "Import from Firefox" module was adapted to read
VORG 2011 boat data files.
Use settings as shown below in the Firefox module.
check [x]Auto import to start periodic updates.
Boat data is read from the plugin-me files, which are
first downloaded 10 min after game reload. So wait
Winds may be obtained from NOAA
(using the grib
import module) or from VRTouToulz
(pointing and pressing F2).
Forecasts used are 6:00Z and 18:00Z (same as VR).
If using NOAA files, select [x]Game Winds (600 and 1800)
set your time zone, resolution=12, up to =72, Grib probe resolution=1.0, interval=12
Set local time of first update. Click Download now!
Check [x]Auto update
to start periodic downloads.*** Wind Interpolation
For a while I've been working on a generic data structure to do interpolation
between discrete values of wind speed/direction. I call this WindCube.
VORG 2011 uses interpolation in position dimensions (lat/lon)
( i.e. the winds change constantly with position ).
To emulate this in vrtool you have to activate the WindCube.
The WindCube is a 3 dimensional grid ( lat x lon x time )
Intermediate values are found by interpolation using different methods.
The figure below illustrates these interpolation types.
For Virtual Regatta games we have interpolation in time=previous
and interpolation in position=nearest
. For this you can leave the
WindCube deactivated (software default)
For VORG 2011 you must set interpolation in time=previous
andinterpolation in position=bilinear
( with [x]WindCube activated)
See below (note the red circles):
The real world, of course, uses none of these methods, but if you setinterpolation in time=quadratic
and interpolation in position=bicubic
you will have a smooth and constantly changing winds (more like the real thing). **** Personal winds
Since winds change continualy, the border between rectangles makes
little sense. Instead you can now plot the wind in the boat position.
Each boat can have its own wind arrow (check [x]show wind
property for each track)
Set boat name and [x]friends update:
Set your time zone (positive for W, negative for E)
