Horizon mapping is a method of shadow mapping specific to height maps. It can handle any angle between 0 and 90 degrees from the ground, as long as know the horizontal direction in advance, by remembering only a single angle (the "horizon angle" of the shadow map). More is explained in common/src/msg/server.rs. We also remember the approximate height of the largest occluder, to try to be able to generate soft shadows and create a vertical position where the shadows can't go higher. Additionally, map generation has been reworked. Instead of computing everything from explicit samples, we pass in sampling functions that return exactly what the map generator needs. This allows us to cleanly separate the way we sample things like altitudes and colors from the map generation process. We exploit this to generate maps *partially* on the server (with colors and rivers, but not shading). We can then send the partially completed map to the client, which can combine it with shadow information to generate the final map. This is useful for two reasons: first, it makes sure the client can apply shadow information by itself, and second, it lets us pass the unshaded map for use with level of detail functionality. For similar reasons, river generation is split out into its own layer, but for now we opt to still generate rivers on the server (since the river wire format is more complicated to compress and may require some extra work to make sure we have enough precision to draw rivers well enough for LoD). Finally, the mostly ad-hoc lighting we were performing has been (mostly) replaced with explicit Phong reflection shading (including specular highlights). Regularizing this seems useful and helps clarify the "meaning" of the various light intensities, and helps us keep a more physically plausible basis. However, its interaction with soft shadows is still imperfect, and it's not yet clear to me what we need to do to turn this into something useful for LoD.
