Hello again,
I'd hate for traffic on this list to lag, so I'll pose a question. :-)
I have a 3D field related to cloudiness (e.g. 0=clear, 1=cloudy). I'd
like to map this to Display.Alpha to get a cool foggy effect. I managed
to do it for a single layer of clouds (with an Integer2DSet, nothing
mapped to ZAxis) but I am not having much luck getting a 3D
representation. The following gives me my 27 data values as *points*
with brightness proportional to cloudiness. (Mapping to Alpha gives me
nothing.) How can I make my scene cloudy?
Thanks,
Doug
RealType lat = new RealType("lat",null,null);
RealType lon = new RealType("lon",null,null);
RealType alt = new RealType("alt",null,null);
RealType[] coords = {lat,lon,alt};
RealTupleType domain = new RealTupleType(coords);
RealType cloud_type = new RealType("cloudy",null,null);
FunctionType cloud_ftype = new FunctionType(domain,cloud_type);
Set grid_set = new Integer3DSet(3,3,3);
FlatField cloud = new FlatField(cloud_ftype,grid_set);
float[][] data = {{0.0f,0.0f,0.0f,0.0f,0.0f,0.0f,0.0f,0.0f,0.0f,
0.5f,0.3f,0.2f,0.3f,0.2f,0.1f,0.2f,0.1f,0.0f,
1.0f,0.75f,0.5f,0.75f,0.5f,0.25f,0.5f,0.25f,0.0f}};
cloud.setSamples(data);
ScalarMap sm_lat = new ScalarMap(lat, Display.XAxis);
display.addMap(sm_lat);
ScalarMap sm_lon = new ScalarMap(lon, Display.YAxis);
display.addMap(sm_lon);
ScalarMap sm_alt = new ScalarMap(alt, Display.ZAxis);
display.addMap(sm_alt);
display.addMap(new ScalarMap(cloud_type, Display.RGB));
//display.addMap(new ScalarMap(cloud_type, Display.Alpha));
