Ogre3d, objekti i materijali

Ogre3d, objekti i materijali 03.09.2006. u 18:48 · pre 245 meseci #1

Posto imam jos pitanja u vezi Ogre-a sugerisano mi je da otvorim drugu temu(hvala franticnick na iscrpnom odgovoru).
U 3DSMax sam kreirao jednostavni objekat (kocku). Dodao sam mu materijal (BeachStones.jpg koji se nalazi u ..\media\materials\textures OgreSDK paketa). U Render prozoru kao i pomocu oFusion paketa se u Max-u objekat noramlno vidi (sa teksturom).
Objekat sam zatim eksportovao u XML pomocu OgreMaxExportera i konvertovao ga u mesh koristeci OGREXMLConverter ("kocka.mesh")

U CreateScene() metod aplikacije sam dodao sledeci kod:

Code:

         mSceneMgr->setAmbientLight( ColourValue( 1.0f, 1.0f, 1.0f ) );

         ent = mSceneMgr->createEntity( "Kocka", "kocka.mesh" );
         node = mSceneMgr->getRootSceneNode( )->createChildSceneNode( "KockaNode", Vector3(  0.0f, -10.0f,  25.0f ) );
         node->attachObject( ent );
         node->setScale( 0.2f, 0.2f, 0.2f );

         ent = mSceneMgr->createEntity( "Knot1", "knot.mesh" );
         node = mSceneMgr->getRootSceneNode( )->createChildSceneNode( "Knot1Node", Vector3(  0.0f, 0.0f,  100.0f ) );
         node->attachObject( ent );
         node->setScale( 0.1f, 0.1f, 0.1f );

U Materials script sam dodao opis materijala:

Code:

material KockaSkin
{
    technique
    {
        pass
        {

            texture_unit
            {
                texture BeachStones.jpg
            }
        }
    }
}

Evo ga isecak iz ogre.log-a (oznaceno sa >>>):

Code:

Kada pokrenem aplikaciju kocka se pojavi na pravom mestu. Medjutim kocka nema teksturu, vec je samo sive boje? Ono sto je interesantno je da pored ovoga je prikazan sasvim normalno drugi objekat (knot.mesh) sa teksturom.

Kako da mi se normalno prikaze tekstura na objektu (onako kako se to vidi uz pomoc oFusion-a u Maxu)?

Posalji mi .xml, .mesh i .material fajlove koje si generisao. Sigurno je neka glupost.

Da li si .material fajl snimio u ..\media\materials\scripts? Moguce je da je i do konvertora jer ih ima u vise verzija, videcemo kada posaljes fajlove.

Citat:

Da snimio sam ga na to mesto. Cak me je Ogre bio i upozorio kada nije uspeo da ga nadje (tada sam ga premestio u scripts).
Svi fajlovi su u prilogu uz poruku.

Evo kako izgleda entitet u Max-u.

Kao da nisi exportovao kako treba. Nemam sad instaliran MAX i oFusion da bih probao, ali vidi da li ima nekih opcija u koje nisi "stiklirao" prilikom eksportovanja.

Posalji mi i .max fajl.

Re: Ogre3d, objekti i materijali 04.09.2006. u 16:57 · pre 245 meseci #6

Probao sam i druge opcije u exporteru (ukljucujuci i Export material) malo pre. Pokusao sam i sa promenom materijala. .Max u prilogu

Da javim da sam uspeo da resim problem. Sve je u redu i sa Ogreom i sa 3DMax-om ali da bi XML exporter pravilno eksportovao podatke o meshu (ukljucujuci i koordinate teksture na entitetu) potrebno je izvrsiti mapiranje direktno u 3DMax-u(Modifiers->UV Coordinates->UVW Map).

Stari XML

Code:

<vertex>
<position x="-49.4253" y="0.0" z="44.4444" />
<normal x="0.0" y="-1.0" z="0.0" />
</vertex>

Novi XML

Code:

<vertex>
   <position x="-49.4253" y="0.0" z="44.4444" />
   <normal x="0.0" y="-1.0" z="0.0" />
   <texcoord u="0.999501" v="0.9995" />
</vertex>

Kao sto se moze videti u novom XML eksportu je i textcoord item :)

E, dobro je.

Nisam bio u prilici da se vise pozabavim tvojim problemom jer sam trenutno u procesu preseljenja. U svakom slucaju, pitaj i ubuduce.
