* Light calculation: New bulk node lighting codeDániel Juhász2017-03-11
| | | | | | | | | | | This commit introduces a new bulk node lighting algorithm to minimize lighting bugs during l-system tree generation, schematic placement and non-mapgen-object lua voxelmanip light calculation. If the block above the changed area is not loaded, it gets loaded to avoid lighting bugs. Light is updated as soon as write_to_map is called on a voxel manipulator, therefore update_map does nothing.
* Lighting: Update lighting at block loadingDániel Juhász2017-02-13
| | | | | This commit updates mapblocks' light if necessary when they are loaded. This removes ghost lighting.
* Improve getPointedThing() (#4346)Dániel Juhász2017-01-04
| | | | | | | | | | | | | | | | | | | * Improved getPointedThing() The new algorithm checks every node exactly once. Now the point and normal vector of the collision is also returned in the PointedThing (currently they are not used outside of the function). Now the CNodeDefManager keeps the union of all possible nodeboxes, so the raycast won't miss any nodes. Also if there are only small nodeboxes, getPointedThing() is exceptionally fast. Also adds unit test for VoxelLineIterator. * Cleanup, code move This commit moves getPointedThing() and Client::getSelectedActiveObject() to ClientEnvironment. The map nodes now can decide which neighbors they are connecting to (MapNode::getNeighbors()).
* Limit light_source in the engine (#4814)juhdanad2016-11-28
| | | Since light_source>15 causes crash, it must be limited.

* Use node lighting for liquid spreadingDániel Juhász2016-10-27
| | | | This commit modifies the liquid transforming procedure to light and unlight nodes instead of whole map blocks.
* Improved lightingDániel Juhász2016-10-27
| | | | | | | | | | | | | | This commit rewrites the procedure that is responsible for light updating. this commit -provides iterative solutions for unlighting and light spreading -introduces a new priority queue-like container for the iteration -creates per-node MapBlock caching to reduce retrieving MapBlocks from the map -calculates with map block positions and in-block relative node coordinates -skips light updating if it is not necessary since the node's new light will be the same as its old light was
