Coastline Maker - concave polygons ?

[GHD 21]

Thanks Luis,Dick has just sent me his new version of TerrainCalc2004 which shows the current bmp and the other 8 surrounding it. It works beautifully.I was able to fly (taxi) around my lake in top-down view and it displayed all of the bmp's required. Now, armed with your alpha channel tutorial it should be easy to uncover the water.Thanks again for such fantastic support,George

Hi Luis.George and I have been in contact, and he has been helping me to squash bugs in TCalc2004. I hope to release this next week ( waiting for some other input, and some communication from flightdecksoftware.com ).The current version seems OK.http://webpages.charter.net/ludowr/TCalc2004_AyersRock_2.JPGhttp://webpages.charter.net/ludowr/AyersRock.JPGHere I have crushed a mesh-clinging smiley face with Ayer's Rock, and placed a nearby label as "19, 4".

Hi Dick,I didn't understand a word of your code, but it has given me an incentive to do some more reading.Just an update on my progress, I have successfully converted one of the bmp's for my lake, just 9 more to go. I am using Lynn and Bill Lyons' water textures which don't really fit with the dark waters of the English Lake District, (well, I was warned by Luis), so I think I will revert to the default VFR water textures.Thanks again for all of your help,George
