Top Layer

+ +Once again, this visualization iterates upon the previous. In the last one the +top layer was able to "see" the bottom, and was therefore able to bolster or +penalize its own elements which were on or near bottom layer elements, but not +vice-versa. This time both layers can see each other, and the "Layer Neighbor +Scalar" can be used to adjust lifetime of elements which are on/near elements of +the neighboring layer. + +By default, the bottom layer has a high affinity to the top, and the top layer +has a some (but not as much) affinity in return. + +Another addition is the "likeness" scalar. Likeness is defined as the degree to +which one element is like another. In this visualization likeness is determined +by color. The "Layer Neighbor Likeness Scalar" adjusts the lifetime of elements +based on how like they are to nearby elements on the neighboring layer. + +By default, the top layer has a high affinity for the bottom's color, but the +bottom doesn't care about the top's color at all (and so its color will drift +aimlessly). + +And finally "Color Drift" can be used to adjust the degree to which the color of +new elements can diverge from its parents. This has always been hardcoded, but +can now be adjusted separately across the different layers. + +In the default configuration the top layer will (eventually) converge to roughly +match the bottom both in shape and color. When I first implemented the likeness +scaling I thought it was broken, because the top would never converge to the +bottom's color. + +What I eventually realized was that the top must have a higher color drift than +the bottom in order for it to do so, otherwise the top would always be playing +catchup. However, if the drift difference is _too_ high then the top layer +becomes chaos and also doesn't really follow the color of the bottom. A +difference of 10 (degrees out of 360) is seemingly enough. + + -- cgit v1.2.3
