Is JSON model format is better for THREE.js -


i using three.js create simple game, load 100 low poly models in obj format performance not smooth, models size not more 18 mb, if use json format faster although size more double? tried collada simple objects case obj faster, if json not best solution, best one?

not 1 file format better overall, depending on needs , requirements external software used , if consist of animation .personally don't use json use obj json heavily supported three.js.. that's more of opinion.

there many factors why application can heavy. out source code or model files can speculate.

few things consider:

are models optimized best can , 100 models in 1 scene quiet allot @ 1 time @ 18mb, including textures?.

are textures compressed , reused.this increase performance. shadows , lighting , animation types have impact, google has plenty of resources offer you.

there several techniques keep poly count down: subdivision example of this, there useful article on this. http://www.kadrmasconcepts.com/blog/2011/11/06/subdivision-surfaces-with-three-js/

also lod level of detail visible depending on how far or near object is. great useful explanation here: http://www.pheelicks.com/2014/03/rendering-large-terrains/ three.js supports out added libs..

detail , how render key best performance..

even down how have set project can have major influence.take @ functions , how use them, example on mouse move , dom element clicks can slow three.js app dramatically if not optimized , used efficiently.

reuse , share best option, there no point in loading same model twice because 1 blue , other green...

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

i added new project. made mistake in projectname.conf file in sites-available apache2, led me reinstalling apache2. after reinstalling , re-enabling projects on every page of every project .. <body> run(); </body> .. i've run composer update, restarted service, restarted pc, checked config files, tried disabling new project. there nothing in error log, , access.log: 127.0.0.1 - - [15/may/2015:01:40:47 +0200] "get / http/1.1" 304 181 "-" "mozilla/5.0 (x11; ubuntu; linux x86_64; rv:38.0) gecko/20100101 firefox/38.0" maybe i'm forgetting apache2 reinstall? don't think did different last time installed it. looks haven't setup php correctly. take @ this great guide , maybe you're forgetting link php config apache2.
