skrócie, co próbuję zrobić, to wziąć obrazy, znaleźć części, które są na tyle niebieski do ich oceany rozważyć, i rozjaśnij te piksele, ponieważ oceany są zbyt ciemne. Pakiet, którego używam (NASA WorldWind) jest napisany w języku JAVA, używając JOGL, więc używam JOGL, aby użyć niestandardowego fragmentu i vertex shader, aby utworzyć ten efekt.
Dzieje się kilka dziwnych rzeczy, które moim zdaniem mogą być oznakami tego, co jest przyczyną braku cieniowania.
Po pierwsze, jeśli moduł cieniujący zostanie zmieniony, aby po prostu pokolorować wszystkie czerwone piksele bez powodu, maszyny robocze będą wyświetlać czerwoną kulę. Maszyny, które nie działają, przesyłają czerwoną kulę przez jedno losowanie, a następnie mapa powraca do oryginalnych obrazów (widać cały glob, a oceany są ciemne).
Po drugie, jeśli zmiana dotyczy pakietu java, tak że pętla renderująca nie wywołuje funkcji glUseProgram (0), działające maszyny renderują się dziwnie, ale wciąż są blisko, a maszyny, które nie działają, będą miały półprzezroczyste sfera, która jest dowolnym kolorem, dla którego ustawiłem GL_fragcolor na w module cieniującym. Jest to tym bardziej dziwne, że ignoruje rozbite piksele i tak czy inaczej je zaciemnia.
Po trzecie, większość informacji na temat debugowania, które otrzymałem od włączenia debugowania jogl, to kosz, ale na maszynie ATI widzę, że dość często pobiera ona teksturę o mocy dwóch, podczas gdy na maszynie nvidia, która robi Nie ma identycznej pary, tekstura potęgi dwa pojawia się raz lub dwa razy na początku środowiska wykonawczego.
Urządzenia cieniujące otrzymują jednolity sampler2D z kodu JOGL i używają go do utworzenia tekstury2D, przez którą kolor piksela jest pobierany.

Jest to również zauważyć, że programowe i Shader infologs podać żadnych informacji o maszynach które nie działają, podczas gdy na maszynie ATI mówią, że udało się skompilować shadery uruchom na tym sprzęcie.
A ważna informacja byłaby również sterowniki zainstalowane, ponieważ dla Linuksa istnieją 2 rodzaje sterowników: the propritary od producenta GPU i sterowniki open source opracowane przez społeczność. Dodaj dane wyjściowe 'glxinfo' dla każdego laptopa. – datenwolf
@datenwolf Zaktualizowany OP za pomocą glxinfo. Wszystkie używane sterowniki to zastrzeżone sterowniki. – Dwight
Kod shadera fragmentu wygląda dziwnie - _two_ otwierając nawiasy klamrowe? Typo? –
