VAO를 사용하는 JOGL에서 텍스처가 검은 색입니다.

Question

지금까지 deprecated 직접 모드 렌더링을 사용했는데 VAO와 VBO로 전환하려고합니다. 2D 쿼드는 일반적으로 VAO를 사용하여 렌더링되지만 질감을 첨부하려고하면 검은 색으로 유지됩니다. 누군가 내 코드를 살펴보고 내가 잘못한 부분을 지적 해 주시면 정말 감사하겠습니다.

    mPosition = new CPoint(dimensions.x, dimensions.y);

녹음 내용 : 내 vcard는 (분명히) VAO 지원과 함께 OpenGL 4.3.0을 가지고 있다고보고합니다. 텍스처가있는 즉시 렌더링이 제대로 작동합니다.

나는 정말로 도움을 주실 것입니다. 미리 감사드립니다.

Answer 1

텍스처 좌표를 확인하십시오.

그래도 효과가 없으면 버텍스 컬러를 흰색으로 설정했는지 확인하십시오 (텍스처에 나타나는 색상이 표시되도록).
