given obb3 (center, halfvector , axis[3]), how can create cube has same bounds obb3 ? i'll use cube display obb3 bounds. i use vector_math , three.dart libraries far, code : matrix3 rot_mat = new matrix3(node.box.axis0[0], node.box.axis1[0], node.box.axis2[0], node.box.axis0[1], node.box.axis1[1], node.box.axis2[1], node.box.axis0[2], node.box.axis1[2], node.box.axis2[2]); vector3 diag = rot_mat.absoluterotate(node.box.halfextents.clone()); var geometry = new cubegeometry(diag[0] * 2.0, diag[1] * 2.0, diag[2] * 2.0); var material = new meshbasicmaterial(color: 0x00ff00, wireframe: true, blending: normalblending, side: doubleside, shading: flatshading); var obj = new mesh(geometry, material); obj.position = node.box.center; obj.matrix.setrotation(rot_mat); obj.updatematrix(); scene.add(obj); thanks lot :]

how model data on form there multiple reviewers. create multiple collections or use array , adding type field? or else? when used multiple instances commented out, created multiple mainform_id in employee table. //main form public class mainform { public int id { get; set; } public virtual icollection<employee[]> employeearray { get; set; } //public virtual icollection<employee> employeereviewing { get; set; } //public virtual icollection<employee> employeesupervisor { get; set; } //public virtual icollection<employee> employeemanager { get; set; } //public virtual icollection<employee> employeebigboss { get; set; } } //employee public class employee { public int id { get; set; } public int programentryid { get; set; } public int reviewertypeid { get; set; } public virtual mainform mainform { get; set; } public virtual reviewertype reviewertype { get; set; } } i not store collections dire

this question has answer here: how clone or copy list? 14 answers i going through python doc when came upon lists , confused these :- 1. >>> = [1, 2, 3] >>> b = >>> a.append(4) >>> [1,2,3,4] >>>b [1,2,3,4] >>> = [] >>> print(a) [] >>> print(b) [1, 2, 3, 4] how can appending a change both a , b using a=[] changes a , not b . as know id(a) != id(a[:]) why doing a[:]=[] changes a ? thank you. references variables point objects in memory. doing b = is making b point same memory location a pointing. this means through both variables b , a can modify same contents in memory, , explains "why modifying b modifies a ". now, when a = [] you creataing new empty list in memory , making a pointing it... of course general explanation, think gives intuiti

i using method azure mobile services tutorial: await todotable.lookupasync(id) . have 2 rows in table of id 1,2. if await todotable.lookupasync(1) , works , return record. if await todotable.lookupasync(8) see how it's going handle null, blows not found exception. thanks on this. null mean there is record id = 8 , value `null'. in case do not have record. different. what observe should observe if do not have record . and standard rest based http services. if record not there, http 404 service. azure mobile services nothing more combination of web api , wrapping (plumbing) code application. , every web api call non-existent record result http 404 error. and said in comments, should wrap code around try - catch blocks , inspect exception. in .net 4.5/4.6 there new httpclient type along httpresponsemessage , httprequestmessatge. former has ensuresuccessstatuscode() method. which, if called trigger exception. in older versions of framework th

just basic newbie question understand reasoning. why should 1 use html helpers available in yii2, or can't type tags if strong in our html skills. example: seen in basic views... <h1><?= html::encode($this->title) ?></h1> why should not type... <h1>my title</h1> it's you. but using framework helpers, widgets , coding styles, can keep code consistency, reduce errors, bugs , lower security risks. using example. imagine $this->title set name of user in main layout file: <?php $this->title = $user->name; ?> <h1><?= $this->title ?></h1> now, let's imagine user managed set username <script>console.log('i can steal cookies now!');</script>notahacker in registration form (also because decided save directly database instead of using framework). that render following: <h1><script>console.log('i can steal cookies now!');</script>notah

i have input forms use on several places on single-page website. there single react-component class named subscribe contains whole <form> allowing user enter email , subscribe newsletter. when user submits subscribes in <subscribe> , want change content of every occurence of <subscribe> on page. easy single <subscribe> user used, can not find suitable way modifiy state of other <subscribe> components. i'm, using plain javascript modifiy dom-nodes. is there way directly in react? yeah, better done flux comment said in post. should store changes , manipulate storage data service. you can check https://facebook.github.io/flux/ further information. but, if you're rendering page react can set state page , pass 1 prop in each <subscribe> component. should manipulate submission in same page or through mixin not let component job state changed well. in page: getinitialstate: function () { return { already
