Strange polygons in your landmass etc.

in Mapping with ProFantasy's Software
Hi!

I've seen this before in CC, but I haven't got a clue what causes it. Can anyone give me advise? I'm making a relatively large map and when mapping the landmass I have to make very many nodes for the coastline to look realistic.

    This usually happens because two nodes are too close. You'll need to find the offending nodes and delete one of them. You can try the DELDUPS command which deletes duplicate nodes, but that will probably not do much, as they are not duplicates, just very close. The REDN command may help, but that will reduce nodes all over your coastline, which is probably not what you desire. Other than that, it is hunting them down manually.

    How do you know where there are nodes too close to each other? Is there any option to make the nodes seen?

    Usually the nodes will be found at the origin of the erroneous lines/polygons, but it is difficult to pinpoint exactly which nodes are the problem. You can often find them by zooming in to the area and notice where your coastline has weird artifacts (triangular holes in the line usually), this indicates a potential problematic area. This often occurs where close nodes and sharp angles happen together.

    Your line itself shows the nodes, there is one in every single bend along the coastline. A node itself is a zero-size point.

    The problem is that finding the trouble spots is difficult, because as I move or zoom the map the odd lines and polygons change each time. I would need to zoom so close that the line fills the whole drawing space and then going through the coastline, but that will take forever. (Sometimes I feel that instead of making mapping easy CC causes me to age prematurely.)

    If you don't have the time to go chasing all those nodes around, I think you may have no option but to use the reduce nodes option (right click the fractalize button and chose "remove nodes") as many times as necessary to get rid of them, even if that does end up simplifying the coastline a bit :)

    For continent fractalizing, I seldom click more than once or twice due to Windows' limits. When I make region or nation maps, I fractalize more. Saved my hair from turning gray... but its already gray so I'm not sure what I accomplish, other than mapping.
