#region Tyrons brain cloud
// Trick 1: Each x/z coordinate gets a "snow accum" threshold by using a locational random (murmurhash3). Once that threshold is reached, spawn snow. If its doubled, spawn 2nd layer of snow. => Patchy "fade in" of snow \o/
// Trick 2: We store a region wide snow accum value for the ground level and the map ceiling level. We can now interpolate between those values for each Y-Coordinate \o/
// Trick 3: We loop through each x/z block in a separate thread, then hand over "place snow" tasks to the main thread
// Trick 4: Lets pre-gen 50 random shuffles for every x/z coordinate of a chunk. Loop through the region chunks, check which one is loaded and select one random shuffle from the list, then iterate over every x/z coord
// Trick 5: Snowed over blocks:
// - New VSMC util: "Automatically Try to add a snow cover to all horizontal faces"
// - New Block property: SnowCoverableShape.
// - Block.OnJsonTesselation adds snow adds cover shape to the sourceMesh!!
// Trick 6: Turn Cloud Patterns into a "dumb slave system". They are visual information only, so lets make them follow internal mechanisms.
// - Create a precipitation perlin noise generator. If the precipitation value goes above or below a certain value, we force the cloud pattern system to adapt to a fitting pattern
// => We gain easy to probe, deterministic precipitation values!!
// => We gain the ability to do unloaded chunk snow accumulation and unloaded chunk farmland rain-wetness accum
// Trick 6 v2.0:
// Rain clouds are simply overlaid onto the normal clouds.
// Questions:
// - Q1: When should it hail now?
// - Q2: How is particle size determined?
// - Q3: When should there be thunder?
// - Q4: How to control the precipitation by command?
// A1/A3: What if we read the slope of precipitation change. If there is a drastic increase of rain fall launch a
// a. wind + thunder event
// b. thunder event
// c. rarely a hail event
// d. extra rarely thunder + hail event
// A2: Particle size is determiend by precipitation intensity
// Trick 7 v2.0
// - Hail and Thunder are also triggered by a perlin noise generator. That way I don't need to care about event range.
// A4: /weather setprecip [auto or 0..1]
// - Q5: How do we overlay rain clouds onto the normal clouds?
// Q5a: Will they be hardcoded? Or configurable?
// Q5b: How does the overlay work? Lerp?
// Q5c: Rain cloud intensity should relate to precip level.
// How? Lerp from zero to max rain clouds? Multiple cloud configs and lerp between them?
// - A5a: Configurable
// A5b: Lerp.
// A5c: Single max rain cloud config seems sufficient
// TODO:
// 1. Rain cloud overlay
// 2. Snow accum
// 3. Hail, Thunder perlin noise
// 4. Done?
// Idea 8:
// - F**K the region based weather sim.
// - Generate clouds patterns like you generate terrain from landforms
// - Which is grid based indices, neatly abstracted with LerpedIndex2DMap and nicely shaped with domain warping
// - Give it enough padding to ensure domain warping does not go out of bounds
// - Every 2-3 minutes regenerate this map in a seperate thread, cloud renderer lerps between old and new map.
// - Since the basic indices input is grid based, we can cycle those individually through time
// for a future version
// Hm. Maybe one noise generator for cloud coverage?
// => Gain the ability to affect local temperature based on cloud coverage
// Hm. Or maybe one noise generator for each cloud pattern?
// => Gain the abillity for small scale and very large scale cloud patterns
// Maybe even completely ditch per-region simulation?
// => Gain the ability for migrating weather patterns
// but then what will determine the cloud pattern?
// Region-less Concept:
// Take an LCGRandom. Use xpos and zpos+((int)totalDays) / 5 for coords
// Iterate over every player
// - iterate over a 20x20 chunk area around it (or max view dist + 5 chunks)
// - domain warp x/z coords. use those coords to init position seed on lcgrand. get random value
// - store in an LerpedWeightedIndex2DMap
// Iterate over every cloud tile
// - read cloud pattern data from the map
// Snow accum needs to take the existing world information into account, i.e. current snow level
// We should probably
// - Store snow accumulation as a float value in mapchunkdata as Dictionary<BlockPos, float>
// - Every 3 seconds or so, "commit" that snow accum into actual snow layer blocks, i.e. if accum >= 1 then add one snow layer and do accum-=1
