Libgdx OpenGL ES 2.0을 사용하지 않음

Question

OpenGL ES 2.0을 사용하여 새로운 3D 게임을 만들고 싶습니다. 어쨌든, 나는 2010 년에 구입 한 Ubuntu PC (최고급이지만 괜찮은)가 아닌 PC에서이 제품을 개발했습니다.

Gdx.graphics.isGL20Available()은 false를 반환하고, 드라이버는 3.3.0을 지원합니다. glxinfo에서받은 내용은 다음과 같습니다.

그리고 훨씬 더 많은 버전 문자열 및/또는 확장자와 관련이 없습니다. OpenGL ES 2.0에 필요한 모든 확장 기능이 있으며 드라이버가 3.3.0 (OpenGL 3.0-> 2.0 ES 정도)으로 업데이트되었습니다. 소프트웨어 래스터 라이저가 오래 되었기 때문입니까? 그렇다면 아마도 같은 상황에있는 다른 사람들이있을 것입니다. (1.1 이전에 업데이트 된 많은 Windows 설치가 있다고 생각조차하지 않습니다.) 나는 그들을 지원하고 싶습니다. 최선의 해결책은 무엇입니까?

Answer 1

Gdx.graphics.isGL20Available()은 하드웨어가 GL ES 2.0을 지원한다고 말하지 않습니다. 그것은 gl20 그래픽 컨텍스트가 초기화되었음을 알려줍니다.

명시 적으로 GL20을 사용하려면 libGDX를 요청해야합니다. Lwjgl 백엔드 예제 :

LwjglApplicationConfiguration config = new LwjglApplicationConfiguration(); 
config.title = "Game"; 
config.width = 800; 
config.height = 480; 
config.useGL20 = true; //this is important 
new LwjglApplication(new YourGame(), config);
