javascript - Three.js imported obj incorrect shadow rendering -

-

i imported object blender, set every mesh of cast , receive shadows, shadows rendered incorrect. merged meshes of object thinking resolve problem, result same. problem seems resolved when using side: three.doubleside, makes materials darken.

light settings

light = new three.directionallight( 0x666666, 1 ); light.position.set(  2*400, 2*300.75, 2*400); light.position.multiplyscalar( 1.3 ); light.castshadow=true; light.shadowmapwidth = 2048; light.shadowmapheight =2048; var d = 1300; light.shadowcameraleft = -d; light.shadowcameraright = d; light.shadowcameratop = d; light.shadowcamerabottom = -d;  light.shadowcamerafar = 10000; light.shadowbias = 0.0001; light.shadowdarkness = 0.5;

material settings

var childtilestexture = three.imageutils.loadtexture('texture/wood_t.jpg?v1'); childtilestexture.wraps = childtilestexture.wrapt = three.repeatwrapping; child.material = new three.meshphongmaterial( { map:childtilestexture, shininess:5, metal: false} );

as can see, handles casting shadow through object box.

the property shadowbias can used remedy self-shadowing problems. try varying it.

try both small negative values, , small positive values.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
