i have 2 vectors same origin, , rotate 1 match other. however, can't find math able compute x angle, y angle , z angle (world coordinates) between two. work angles in local coordinates, don't know if helps rotation around forward vector (local y) can doesn't matter. need object facing right direction. how ? there many ways approach this. let me first suggest cross product , easier understand alternatives (like quaternions) , might point in right direction. basically cross product between 2 vectors ( a , b ) results in third vector ( c )which perpendicular both. interesting note, length of third vector length(a)*length(b)*sin(theta) , theta angle between a , b . here looks like: c.x = a.y * b.z - a.z * b.y c.y = a.z * b.x - a.x * b.z c.z = a.x * b.y - a.y * b.x a simple formula. now trick is, normalize a , b . means set length 1. done taking vector , dividing each component it's length length_a = sqrt(a_old.x * a_old.x + a_old.y * a_old.y +...
