i'm working on toy backbone.js application, library application perform crud operations on library. here book model , library collection (of books) var book = backbone.model.extend({ url: function() { return '/api/books' + this.get('id'); } }); var library = backbone.collection.extend({ model : book, url : '/api/books' }); this seems pretty straightforward. next, want able show book, have bookview... var bookview = backbone.view.extend({ tagname: 'li', render: function() { this.$el.html(this.model.get('author')); $('#list-of-books').append(this.$el); } }); all render method append li end of unordered list id of list-of-books in html. next, unsurprisingly, if add following code, list 1 item (the name of author of book id=4) var a_book = new book(); a_book.url = '/api/books/4'; a_book.fetch({ success: function() { var bookview = new bookview({ model...

i want create interactive panorama one: http://mrdoob.github.io/three.js/examples/webgl_panorama_equirectangular.html but want let user interact it. is possible coordinates texture on mouse move create 3d image map three.js? thanks! check this: translating mouse location object coordinates when found triangle ray intersects, can gather triangles vertices 3d coordinates , uvs. there have enough data calculate uv position intersection point. pseudo-code: x0 = mouse.x; y0 = mouse.y; vec3 samplepoint = unproject(x0, y0); // returns (x, y, near-plane-z) coords ray.origin = camera.position; ray.direction = samplepoint - camera.position; var trianglecomplexobj = check_for_intersections( scene, ray ); // returns triangle, it's vertices , uv , 3d coord , intersection coord calulateuv( trianglecomplexobj , trianglecomplexobj.intersectionpoint ); it's maybe bit complex understand should trick. hope helps.

today, i've participated in google code jam round 1b. in code jam, there problem called 'osmos': https://code.google.com/codejam/contest/2434486/dashboard problem description the problem states there's game, player thing, can eat things smaller it, , become larger size of thing ate. example, if player has size 10 , eats of size 8, becomes size 18. now, given size player starts off at, , sizes of other things in game, should give minimum number of operations required make game beatable, means you're able eat everything. an operation can either adding thing, or removing thing. the code used write_case function writes output every test case in right format. i've used in other code jam rounds, , know correct, , inp file object of input file. cases = int(inp.readline()) case in xrange(cases): # armin variable containing size of player, armin, n = int(inp.readline.split()[0]) # others list of sizes of other things others = [int(x) x...

as title says, i'm trying fetch 10 photos in logged user , 1 or more of his/her friends tagged. i'm trying php api , fql. i'm new fql, not new programming etc. way able achieve want dynamically building multiple queries this: select pid, src_big photo pid in( select pid photo_tag subject = me() ) , pid in( select pid photo_tag subject = '1530195' or subject = '3612831' or subject = '6912041' or ... ) apart being ugly, slow. queries limited length shown above because fail when longer. multi-queries didn't me because can't use 'as', sql isn't greatest strength , i'm hoping i've missed something.. there must better way! anyone? just use 2 queries , intersection in programming language of choice. select subject, pid photo_tag subject = me() select pid, subject photo_tag subject in (select uid2 friend uid1=me()) batch these 2 calls fql?q={"userphotos":"s...

well i'm using simpleshapechecker.iscircle method detect pupil. work fine, when sides pupil turns oval/ellipse shape. there method detect ovals?, or there way "relax" iscircle() method? thanks unfurtunately in aforge there not isoval() function. but can take @ source code of shape checker! https://code.google.com/p/aforge/source/browse/trunk/sources/math/geometry/simpleshapechecker.cs?r=1402 you can see iscircle() function , modify see if oval or not. this function: public bool iscircle( list<intpoint> edgepoints, out point center, out float radius ) { // make sure have @ least 8 points curcle shape if ( edgepoints.count < 8 ) { center = new point( 0, 0 ); radius = 0; return false; } // bounding rectangle of points list intpoint minxy, maxxy; pointscloud.getboundingrectangle( edgepoints, out minxy, o...

for simple overview screen have developed route sets controller app.location.find(). app.locationsindexroute = ember.route.extend({ setupcontroller: function(controller) { controller.set('content', app.location.find()); }, rendertemplate: function() { this.render('locations.index',{into:'application'}); } }); i naively assumed go store , fetch me records, giving me up-to-date view of records. apparently not.... when external process starts removing records database, app.location.find() keeps on returning these deleted records. (although rest call doesn't show them anymore) if external process starts adding records database, app.location.find() picks them up. if delete records form within ember app model correctly updated. how should deal in ember app ? i'd have up-to-date view on whatever in database. right need refresh page (f5) date view. using linkto helpers shows me stale data. this seems yet trivial thing misse...
