>The final steps involve finding a base using (f-1)/8 for each of the eight triangles (some a bit bigger than others by a unit in length) which is larger than (n-1)/8 BUT smaller than (x+n)/8.
>larger than (n-1)/8 BUT smaller than (x+n)/8
For each given (x+n), there is a range of possible n values and a range of possible x values. Picture 2 shows this pretty well. For (x+n) = 9, n-1 is going to be in the range of 0 to 5 and x is going to be in the range of 3 to 8. Picture 1 was related to something else (I had found linear gradients in a bitmap but they didn't lead to anything because of the thing this picture explains), but it shows what VQC is talking about here: the range of n values and the range of x values overlap. If we don't know (x+n) but we want to set an n0 value based on our known f value, the minimum possible (x+n) and maximum possible n values for our given c also overlap in the same way (that's what the gradients were about, and I guess it's finally relevant). So n0 is currently a guess within an overlapping range. I could see if I can find the gradient picture and use it to make an equation for finding the range of n and (x+n) for a given c if that would help (it sounds like it would to me but I don't tend to get feedback about these things).
Well thank you for the encouragement VA. I'm glad we all have good comradery here. You seem to be a big part of that. I think that first logo looks a lot less like a sigil compared to the other ones so I'd agree with your choice.
