three.js - Dynamically change .mtl of .obj OBJMTLLoader -


how can dynamically change material on .obj model? each of model contains .obj, .mtl , .jpg files textures. should change .mtl file somehow?

in code below center geometries of each child mesh of .obj , try give texture, neither commented code nor loader.load not giving texture.

var loader = new three.objmtlloader();             loader.addeventlistener( 'load', function ( event ) {                 object = event.content;                 (var = 0; < object.children.length; i++) {                     three.geometryutils.merge(geometry, object.children[i].geometry);                 }                 three.geometryutils.center( geometry );                 //var materials = new three.imageutils.loadtexture("/obj/stol.mtl");                 //mesh = new three.mesh( geometry, new three.meshfacematerial( material ) );                  var material = new three.meshbasicmaterial( { color: 0xff0000 } );                 mesh = new three.mesh( geometry,  material );                  mesh.scale.x = 0.25;                 mesh.scale.y = 0.25;                 mesh.scale.z = 0.25;                 mesh.castshadow = true;                  scene.add( mesh );                 animate();             });             loader.load( '/obj/stol.obj', '/obj/stol.mtl' );

i'd have buttons on page trigger texture changes onclick, e.g

$(function(){     $('#txt_01').click(function(){         mesh.textureload("/obj/txt_01.mtl");     } });

working demo: http://www.edar.com.pl/test-3d-2/

just check examples loading texture.

and how update stuff in three.js , see "material update" section. https://github.com/mrdoob/three.js/wiki/updates

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
