DS	2332527765	Add vector.to_string and vector.from_string (#10323) ... Writing vectors as strings is very common and should belong to `vector.*`. `minetest.pos_to_string` is also too long to write, implies that one should only use it for positions and leaves no spaces after the commas.	2021-04-05 15:55:56 +02:00
Vincent Robinson	3560691c0a	Add math.round and fix vector.round (#10803)	2021-04-02 00:18:58 +02:00
DS	28e87ce9d5	Add vector.offset (#10321)	2020-08-29 16:41:29 +01:00
NetherEran	7148834440	Some vector functions useful for working with rotations (#9572) ... * added vector.rotate * added vector.forward_from_rotation and vector.up_from_rotation * added vector.forward_up_to_rotatiton * fixed some bugs and formatting with vector functions * shortened name of some new vector functions and added documentation * made vector.rotate not require a unit vector as axis * fixed crash with vector.forward_up_to_rot * renamed new vector functions, made vector.rotate apply a rotation matrix, old vector.rotate is now called vector.rotate_around_axis * documented vector function changes * removed some whitespace to appease luacheck * implemented and fixed optimization of vector.rotate_around_axis by SmallJoker * added some unit tests for rotation vector functions * clarified that rotation vectors are in radians and according to the left hand rule * hopefully appeased luacheck * renamed rotation_to_horizontal to forward_at_rotation, rotation_to_vertical to up_at_rotation * handled cases where sin or cos are 0 in rotation vector functions * added more comments * clarified documentation of rotation vector functions * added more unit tests * changed way in which vector.rotate_around_axis is adjusted for left handed coordinate systems * made vector.rotate_around_axis actually left handed * unrolled matrix multiplication * removed vector.forward_at_rotation and vector.up_at_rotation * prettified vector.rotate_around_axis, made previous commits not break anything * removed references to removed vector.forward_at_rotation and vector.up_at_rotation * removed documentation of removed vector functions * clarified documentation and fixed styling of rotation vector functions * restyled comments minorly * spelling fixes and some hopefully better comments * allowed 'up' to be missing from vector.directions_to_rotation and removed requirement for unit vectors as arguments * made vector.rotate_around_axis() right handed again for consistency * documented previous changes * made matrix multiplication actually multiply * renamed vector.directions_to_rotation() to vector.dir_to_rotation() * optimized a distance comparison * Fixed potential false positive in unit tests.

ANAND	7f1c2b8a00	Builtin: Add vector.angle(). Returns the angle between 2 vectors (#7738)	2019-03-17 02:05:03 +00:00
Paramat	d04c41ad80	Vector functions: Fix vector.direction() function, improve documentation (#6801) ... vector.direction() now returns a normalised vector with direction p1 to p2.	2017-12-21 20:57:42 +01:00
Auke Kok	2d7a6f2cc0	Vector: Add vector.sort(a, b): return box edges ... This function returns the box corners of the smallest box that includes the two given coordinates.	2017-01-23 07:38:39 +00:00

ShadowNinja	33ca115ae4	Remove vector assertions ... These were initially added to get tracebacks for invalid vector errors, but it didn't work and tracebacks have since been properly fixed in the core.	2014-07-19 23:50:50 -04:00
