i need formula calculating camera x y position force given 3d point appear in center of screen. in other words, camera pans move point center, without changing fov, rotation, or z co-ordinate. let's assume current camera position campos , direction camdir . depending on projection, there several options how view ray screen center calculated of time just: ray(t) = campos + camdir * t we don't want change position's z-coordinate. calculating parameter t hit target point p quite simple (given position had correct x , y coordinates): t = (p.z - campos.z) / camdir.z we can calculate current point @ screen center @ given depth by: currentscreencenter = campos + camdir * t in order hit p , campos has shifted difference: campos += (p - currentscreencenter) = p - campos - camdir * (p.z - campos.z) / camdir.z

this question has answer here: var functionname = function() {} vs function functionname() {} 28 answers i understand function expressions must expressed @ top if want use them vs function declarations hoisted top. when call constructor window.onload, works. if don't have window.onload, , call constructor before function expression, code breaks. <script type="text/javascript"> window.onload = function () { var c = new c(); } // works, if delete window.onload code breaks. var c = function () { console.log("test"); }; </script> that's simple. window.onload executed later, when c defined, if call new c throw because c undefined. move call after definition, or define using 'function' keyword, not 'var'

i using em-websocket make communication clients (may 2 or more users). in introduction . https://github.com/igrigorik/em-websocket i want modify simple echo server example achieve purpose. but in example , handshake.path output show "/" . i cannot know client . is there have solution can know client source place , make broadcast message of them ? i found answer in example. https://github.com/igrigorik/em-websocket/blob/master/examples/multicast.rb eventmachine::websocket.start(:host => "0.0.0.0", :port => 8080, :debug => true) |ws| ws.onopen { sid = @channel.subscribe { |msg| ws.send msg } @channel.push "#{sid} connected!" ws.onmessage { |msg| @channel.push "<#{sid}>: #{msg}" } ws.onclose { @channel.unsubscribe(sid) } } end but still have problem that: how can send message specified clients? (e.g.) 2 clients (no.1 , no.2) make own communication.

follow here: getting lowest level in tree higher level self-join i realized asking wrong question. have hierarchical table looks this: type | code | parent_type | parent_code 4 | 123 | 2 | 1 4 | 234 | 2 | 1 6 | 1234 | 4 | 123 6 | 2345 | 4 | 234 7 | 12345 | 6 | 1234 7 | 23456 | 6 | 1234 7 | 34567 | 6 | 2345 it maps "type 2" codes "type 4", "type 4" "type 6" , "type 6" "type 7". previous question (and answer) dealt how select type 7 codes under single parent code. so, example, how type 7 codes under type 2, code 1. but need join table list of types , codes. example, might have table: type | code 4 | 123 6 | 7851 and need level 7 codes under both codes. in other words, ( i think ) need flatten hierarchy this: type | code | parent_type | parent_code 7 | 12345 | 2 |...

the body of while (or other of java's loops) can empty. because null statement (one consists of semicolon) syntactically valid in java. consider : i = 100 j = 200 while(++i < --j); // no body in loop system.out.println(i); system.out.println(j); i noticed if value of less j, loop repeats , when condition fails fulfill, 2 below statements exceuted. correct or there other logic behind this? yes, continues repeat without executing other statements. it test conditions 101 < 199 , 102 < 198 , , on, until tests 150 < 150 . breaks out of loop , executes println statements. output: 150 150 note reason it's not infinite loop condition changing values ++ , -- operators.

this question has answer here: how numeric column values? 5 answers i'm hoping there basic string function haven't found yet. specifically scenarios length of string unknown: there succinct method of telling if string variable contains [0-9] values? for example, following method works require additional mention of possible characters appear other numerals. select var #table1 var not '%[a-z]%' and select var #table1 var '[0-9][0-9][0-9][0-9][0-9]...' doesn't work because length of var required filter. thanks in advance select var #table1 var not '%[^0-9]%'
