    These look very solid...probably cuz you put a lot of thought into it. That third one looks a lil iffy with how the continents are smashed right up against the plate boundaries but, then again, I'm no geologist either. Keep up the nice work.

    Yeah, I'm not too sure about that one either. The west coasts of North and South America are on plate boundaries, but I think I need to work on the transition a bit more.

    Possibly running and exponential filter against it would flatten the coastal areas. Or some simple erosion model or slope limiting.

    Question

    After a very long time lurking I'm finally in my element and need to post.

    I don't suppose you could indicate on your examples which plate boundaries are convergent and which are divergent could you? Just some simple arrows pointing in towards or away from each boundary would do.

    It would be very useful in critiquing the results. Not that I'm trying to sound disparaging, I think this will be utterly brilliant.

    Sure. I've also changed how the boundaries are made: the previous version had each plate either expanding or contracting on all edges (which wasn't very realistic but seemed easier at first glance), but now the individual boundaries themselves are randomly determined.

    Here are some new maps, still suffering from the same discontinuity problems, but now with transform boundaries in gray, divergent in blue, and convergent in red.

    AidenPrice: Welcome, post an intro message Your handle rings a bell from distant memories too but I cant think why. Anyway, good to see you here.

    Isomage: Good stuff. I agree that rand terrain generators suffer in the way your trying to fix and this looks like a good way to do it. Interesting. I think su-liam uses libnoise too - you might tap him if he comes on line too. Its looking good so far so keeping an eye on this.

    It's written in C and uses libnoise to perturb the plate boundaries and generate the base heightfield.
