내 큐브가 LWJGL/OpenGL에서 제대로 그려지지 않는 이유는 무엇입니까?

Question

그리기 순서와 관련이 있다고 생각하지만 지금은 포기했습니다. 기본적으로 쿼드는 그리기는하지만 올바른 순서가 아니며 후면 컬링이 활성화되어 있지만 도움이되지 않습니다.

Answer 1

GL11.glEnable(GL11.GL_CULL_FACE|GL11.GL_DEPTH_TEST);

당신은이 작업을 수행 할 수 없습니다. 각 glEnable을 별도의 명령으로 제공해야합니다. 대신이 방법을 사용해보고 도움이되는지 확인하십시오.

GL11.glEnable(GL11.GL_CULL_FACE); 
GL11.glEnable(GL11.GL_DEPTH_TEST); 

glGetError도 사용하십시오!
