c# - Rotation between vectors -


i have next problem. there system of objects. ray hit them all. , stay along 0z axis.

next add mirror between 2 random objects. , @ last need rotate objects after mirror around mirror point (mirror position or point o). , ray should hit them, there isn't mirror. need rotation angles around x,y,z-axes?

i have x,y,z-angles of mirror rotation , mirror position (point o). tried. first got vector along axis 0z first "reference" object mirror (ao). applied transform x,y,z-angles mirror vector - , got normal vector form mirror (on). @ last calculate vector of reflected ray using ao , on (dot , lengths).

what need next? or there way angles?

p.s. write code on c#. structure of point or vector - point3d(double x, double y, double z)

var mirrorposition = mirrordata.position; var referenceposition = referenceobject.position; var vectortomirror = mirrorposition.substract(referenceposition); var mirrorrotation = transformation.createrotationmatrix(mirrordata.xangle,  mirrordata.yangle, mirrordata.zangle); var mirrornormal = new point(0,0,1).multiply(-1).transform(mirrorrotation); var vectorreflect = reflectvector(vectortofoldmirror, mirrornormal);

transformation.createrotationmatrix - creates rotation matrix angles aroung 0x, 0y, 0z , central point (0,0,0).

substract = vector 1 - vector2. multiply = vector1 * vector2 or vector * double.

private point3d reflectvector(point3d source, point3d reflect) {      var dot = getdotproduct(source, reflect);      return source + ((-2 * dot) * reflect); }  private double getdotproduct(point3d vector1, point3d vector2) {     return vector1.x * vector2.x         + vector1.y * vector2.y         + vector1.z * vector2.z; }

rotated system:

neo4j - finding mutual friends in a cypher statement starting with three or more persons -

Image
i trying build cypher statement neo4j know 2-n starting nodes name , need find node (if any) can reached of starting nodes. at first tought similar "mutual friend" situation handled (start1)-[*..2]->(main)<-[*..2]-(start2) in case have more 2 starting points around 6 know name. so puzzled how can include third, fourth , on node cypher able find commmon root amongst them. in above example neo4j website need path starting 'dilshad', 'becky' , 'cesar' check if have common friend (anders) excluding 'filipa' , 'emil' not friends of three. so far create statement programmatically looks like match (start1 {name:'person1'}), (start2 {name:'person2'}), (start3 {name: 'person3'}), (main) (start1)-[*..2]->(main) , (start2)-[*..2]->(main) , (start3)-[*..2]->(main) return distinct main but wondering if there more elegant / efficient way in cypher possibly use list of names parameter ...

based on picture above result of var_dump() , dd() of same variable ,when var_dump() , apostrophe (') symbol in black diamond of question mark , when dd() same variable , apostrophe can seen letter 'b' appear in front of words what want can me result : loreal's sdn bhd and @ same time want remove special character ( excluding these 4 symbols (-) ,(_) ,('),(,) ) simply escape special character resolve issue. mysqli_real_escape_string resolve issue. $name = mysqli_real_escape_string($request()->user); or use addslashes function() $name = addslashes($request()->user);

minify - Minimizing css files -

i want know how css files can minimized. currently, using external sites css minifier compress css files. however, after removing whitespaces, comments, etc, file sizes reduced 10-15%. how frameworks bootstrap manage make minimized versions kilobytes. as example, css is: body { background-color: #ff0; } the reduction goes 28 bytes 22 bytes other css files have lot more characters still smaller this. actually minifying code means it's remove thing code white space characters new line characters comments block delimiters it reduces amount of code has transferred on web , speed site load fastly.but unreadable format.
