Uporaba mešalnika za ustvarjanje modelov Java3D: 3 koraki

Če ste programer Java, ste verjetno kdaj želeli programirati v 3D. Ampak kako? No, lahko uporabite Java3D in počasi vnesete vsako točko v 3D poligonu (poskusite, verjemite, to je slaba ideja) ali pa uporabite Blender (https://blender.org) brezplačen in odprtokodni program za 3D modeliranje skupaj z skript z imenom Blend2Java (https://sourceforge.net/projects/blend2java/). Vendar dokumentacija o Blend2Javi skoraj ne obstaja, zato sedim tukaj in pišem to.

1. korak: Prenesite programe

Potrebovali boste Blender (https://blender.org) in Blend2Java (https://sourceforge.net/projects/blend2java/). V redu, potem ko oba začnete z izdelavo preprostega modela (ali samo s standardno kocko) v Blenderju.

2. korak: izvozite svoj model v XML

Ko imate model, ki ga želite uporabiti v mešalniku, odprite način za urejanje in pritisnite tipko "a", da izberete vse točke. Na spodnji plošči izberite urejevalnik besedil. Odprite novo datoteko v urejevalniku besedil. Odprite datoteko blend2java.py, ki ste jo prenesli. Run. Ok, vaš objekt bi moral biti zdaj v. XML, kjer koli ste ga shranili (če imate in sporočilo o napaki, se prepričajte, da imate samo 1 material za predmet). Preimenujte predmet (ime bo čudno).

3. korak: Uvozite objekt v Javo

Shape3D fred = nič; poskusite {XMLDecoder e = nov XMLDecoder (nov BufferedInputStream (nov FileInputStream ("c: /HandShape3D.xml"))); // ime vaše datoteke tukaj fred = (Shape3D) e.readObject (); e. Zapri (); } catch (izjema e) {e.printStackTrace (); } ColoringAttributes at = new ColoringAttributes (); Videz ap = nov videz (); Color3f col = nov Color3f (1.0f, 0.0f, 1.0f); ColoringAttributes ca = new ColoringAttributes (stolpec, ColoringAttributes. NICEST); ap.setColoringAttributes (ca); fred.setAppearance (ap); obj.addChild (fred); vstavite to v katero koli 3d kodo ali uporabite celotno kodo tukaj uvoz java.io.*; uvoz java.beans.

Nimam pojma! Pred enim mesecem sem se naučil Javo lol!
