Interfaces are luxuries at this point. Right now, I just want to focus on finishing the TGD file. Once that's done, I would love to have a plugin or something that would allow a user to easily manipulate the TGD with some basic sliders/controls. Basically, instead of manipulating 10 different values to get your continents to have more satellite islands, or fewer, you could just move a slider in the plugin that says "amount of satellite islands". But I think the only way that's going to happen is if I can find someone who knows how to do that.
Progress update: I've implemented the initial stages of the climate mapping system, which will form the foundation of the soon-to-be-implemented biome distribution network. The climate mapping system largely determines temperature levels around the planet and is also directly responsible for creating and shaping the icecaps, including permafrost and snowfall. It will be used to map equatorial climates like jungles and deserts, seperating them from temperate climates like forests and grasslands. Arctic climates will most likely naturally occur as the temperate band thins into the icecaps. Most of these areas will be dominated by biome-less land (tundras), and some of the pole-ward forests will naturally blend into thier icecap's snowbound regions, creating alpine forests that thin out gradually.
I have included some renders illustrating the false-colored climate mapping system. The reddish/pink areas indicate hot regions where deserts, tropics, and swampland will appear, while the grey will be mostly occupied by temperate climates. The white areas indicate icecaps. There are also beaches, indicated by yellow areas along the coasts. These are more noticeable at lower altitudes and some of them span nearly 100 miles from the coastline, creating vast areas of inland dunes.
