SCASM source.

Recommended Posts

If I am creating the source for an LWMDataAreaDrawPolygons and the LWMPoly3 would contain just the four corner points of the area, is there a another macro which is more efficient than LWMPoly3.In other words, how do I specify that the whole area is to contain water?George

Hello Luis,What I would output for a full LOD13 area would be: LWMDataAreaDrawPolygons 1,_Transparent_,1,28,6 LWMPoly3 4, 0, _Water_, 122, 27, 122, 27 LWMPoint3 0, 0, 0 LWMPoint3 255, 0, 0 LWMPoint3 255, 255, 0 LWMPoint3 0, 255, 0I just wondered if there was a more elegant solution.Regards,George

Hi George.You could make an areafill:LWMDataAreaFill1x1 0, _Water_, 1, 28, 6LWMDataAreaHeight 122, 27If I remember correctly, we have a problem with the Map view or GPS, and the areafills. You might need to check that out before using them.Dick

Thanks Dick,That is what I was looking for, however, if there might be a problem, perhaps I should stick to using LWMPoly3's.What I have done is written a program to convert the output of Steve Greenwood's FSTFlatten program to LWM format using your kindly supplied code for lat/long conversion and Jim Kier's graphics code and during this realised that there might be some areas which are completely filled, see the rectangular area in the test output below.Georgehttp://www.geo-davison.demon.co.uk/Flatten2LWM.jpg

Hi George.I'm not certain there is a problem, but you might need to do a search of the forum for "LWMDataAreaFill", and see what comes up.I'll look this weekend, as well, and see if I can recreate any problem to verify.Dick

Hi Dick,I did the search, but most of the topics were from about two years ago and applied to FS8 and CFS2.As I am about to implement the output code, I think I will carry on using polys.George
