vreau sa implementez in java ceva functii simple de opengl...sa desenez niste figuri si sa le suprapun.
folosesc pachetul javax.media.opengl.
public void display(GLDrawable gLDrawable)
{.....
final GL gl = gLDrawable.getGL();
gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT);
gl.glLoadIdentity();
.....
}
Problema este aici : final GL gl = gLDrawable.getGL();
nu-mi recunoaste metoda getGL() desi am inculs
import javax.media.opengl.GLAutoDrawable
http://download.java.net/media/jogl/builds...blic/index.html
ceva i-mi scapa.m-ati putea ajuta?
zi eroarea completa, eventual pune tot codul
am pus codul aici....am inclus mai toate librariile dar tot degeaba nu -mi recunoaste medoda getGL() si getGLU():

pai GLDrawable nici nu defineste metodele alea doua, ele sunt definite in GLAutoDrawable
faza e ca eu am inclus GlAutoDrawable si tot aceeasi eroare i-mi da....tot nu sti cine e getGL() si getGLU()
am citit si eu pe net ca cele doua functii sunt implementate in GlAutoDrawable.....da nu inteleg at de ce nu mi le vede.Aveti vreo idee?
am citit si eu pe net ca cele doua functii sunt implementate in GlAutoDrawable.....da nu inteleg at de ce nu mi le vede.Aveti vreo idee?
pai eu vad ca in cod tot pentru GLDrawable incerci cele doua metode
CODE
public void display(GLDrawable gLDrawable)

final GL gl = gLDrawable.getGL();

merci mult aveai dreptate..nu am fost atent.
am facut ceva modificari......dar acum nu stie cine este getGLU()!!!!!!!!!!!!!!

1) nu iti da dupa compilare ca iti da la rulare. exprima-te corect.
2) incearca sa folosesti tagul CODE.

Cine crezi ca iti citeste tie codul asta neformatat?
Tu l-ai putea citi la o prima vedere!?
Invata sa folosesti formatarea de cod-->
[code_] Codul tau aici.. i[/_code]
PS.
Trebuie eliminat caracterul " _ " din expresia : [code_] Codul tau aici.. i[/_code]
Exemplu :
line1
line 2
line3
Vad ca ti-a mai zis careva dar .. nimic!
Multa bafta

Am verificat si e pe bune! La job.ro se dau super premii: 8 Sony Vaio, 8 HTC-uri cu Windows si GPS si 16 iPod-uri Nano de 8Gb.
Si culmea, daca le spui si prietenilor tai ai sanse mai mari de castig
