Blender mesh importer

[xcx]

W.I.P, mutta näytti toimivan. Hyvin yksinkertainen mesh importer. Tuo vain geometrian ja pitää pivotin oikeassa paikassa ja orientaatiossa. Tarkoitus tälle on tuoda dummy obuja simulaatioita varten. Eli tämä ei ole sopiva varsinaisten rendattavien meshien tuomiseen. Animaatio importer seuraa perässä, kun löytyy sopiva väli tehdä se.

Nysvään tästä vielä käyttäjä ystävällisemmän jossain vaiheessa, mutta jos joku haluaa kehitellä tai kokeilla niin tässä tämän hetkistä koodia.

Specsit tiedostoformaatille. Pyrin pitämään formaatin helppona lukea, joka varmaan puree perseelle kohtapuoleen, mutta toistaiseksi näin.

Rivi 1: Meshin lukumäärä
Rivi 2: Ensimmäisen meshin nimi
Rivi 3: Verteksien lukumäärä
Rivi 4: Facejen lukumäärä
Rivi 5: Meshin position ( world coords. )
Rivi 6: Meshin rotaation ( world coords. )
*: Verteksien data ( [ x, y, z ] local coords. )
*: Face data ( [ x, y, z ] euler rad )
*: Seuraava mesh ( kts. rivi 2 )

[ajuss]

hei,
toimiiko ne blenderin skriptit Blender 2.5 Alpha 1:llä?

[xcx]

Ei. Nää on vanhalle 2.49 versiolle. 2.5:lle ei varmaan isoja muutoksia tarvii tehdä, mutta en halunnut alkaa kirjoittaa alpha versiolle scriptaa. Niistä kun ei aina voi sanoa, että missä mättää jos jokin ei toimi.

[xcx]

Jaa niin ja unohdin antaa specit tohon animaatiofilun formaatille.

Rivi kerrallaan luetaan, jokainen rivi on yhden obun transformaatio per frame.

Ensin obun nimi, frame, transformaatiomatriisin row1, row2, row3 ja row4 (position). Blender haluaa nämä 4x4 matriisina joten kirjoita matriisi muodossa.

row1.x, row1.y, row1.z, 0
row2.x, row2.y, row2.z, 0
row3.x, row3.y, row3.z, 0
row4.x, row4.y, row4.z, 1

Animaatio on normia FK animaatiota ja ei tue hierarkiaa. Blender kuitenkin settaa matriisit aina relatiivisesti suhteessa parenttiin, joten älkää yrittäkö pistää obuja hierarkiaan.
