* Biomes/decorations/ores: Make relative to 'water_level' settingparamat2017-07-11
| | | | | | | | Add 'biome_zero_level' argument to 'generateBiomes()', 'deco_zero_level' argument to 'placeAllDecos()' and 'ore_zero_level' to 'placeAllOres()' to allow mapgens to vertically shift the registered biomes, decorations and ores per-mapchunk. Will also allow many realm possibilities in future mapgens.
* Ores: Make 'absheight' flag non-functionalparamat2017-06-26
| | | | | | | | | | | | | | The 'absheight' flag was added years ago for the floatlands of 'indev' mapgen (now deleted). The feature mirrored all ore placement around y = 0 to place ores in floatlands. In MTG we now use dedicated ore registrations for floatlands. The feature is crude, inflexible, problematic and very rarely used, it also makes ore vertical range code more complex. Minetest 0.5 is a good chance to remove the feature. The flag itself remains to not break flag values.

* Clean up numeric.h and split FacePositionCache from itShadowNinja2017-05-06
| | | | | I also optiized FacePositionCache a bit: I removed a map lookup and vector copy from both branches of getFacePosition.
* Permit usage of std::unordered_map & std::unorderered_set on c++11 compilers ↵Ner'zhul2016-08-10
| | | | | | | | | (#4430) This fallback to std::map & std::set for older compilers Use UNORDERED_SET as an example in decoration and ore biome sets Use UNORDERED_MAP as an example in nameidmapping
* Sheet Ore: Eliminate crash caused by PcgRandom range max < minparamat2016-02-23
| | | | | | | | | | | | In the calculation of y_start, when 'column height max' was large it caused nmin.Y + max_height > nmax.Y - max_height Now, in this situation y_start is set to the midpoint between nmin.Y and nmax.Y Limit y0 and y1 to between nmin.Y and nmax.Y, otherwise index calculation, which has no checks for limits, places them at unwanted locations in the voxelmanip
* Convert usages of PseudoRandom to PcgRandom for ore and deco placementkwolekr2015-11-09

* Ore: Add ore sheet column height range selectionkwolekr2015-09-13
| | | | | | | | Modders are now able to select the range of ore column height, and the midpoint at which they 'grow' starting from. This commit adds three new parameters for the 'sheet' ore type: column_height_min, column_height_max, and column_midpoint_factor. clust_size is now deprecated for this ore type.

* Schematics: Refactor NodeResolver and add NodeResolveMethodkwolekr2015-04-16
| | | | | | | | | NodeResolver name lists now belong to the NodeResolver object instead of the associated NodeDefManager. In addition to minimizing unnecessary abstraction and overhead, this move permits NodeResolvers to look up nodes that they had previously set pending for resolution. So far, this functionality has been used in the case of schematics for serialization/deserialization.
* GenElementManager: Pass opaque handles to Lua and rename to ObjDefManagerkwolekr2015-03-31
