我GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT尝试创建渲染到纹理的帧缓冲区后出错.我无法弄清楚出了什么问题,非常感谢任何帮助.

编辑:修复它!工作代码:

    glGenTextures(1, &texture);
    glBindTexture(GL_TEXTURE_2D, texture);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
    glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, 768, 1024, 0, GL_RGBA, GL_UNSIGNED_BYTE, 0);
    glBindTexture(GL_TEXTURE_2D, 0);

    glGenRenderbuffers(1, &rboID);
    glBindRenderbuffer(GL_RENDERBUFFER, rboID);
    glRenderbufferStorage(GL_RENDERBUFFER, GL_DEPTH_COMPONENT16, 768, 1024);
    glBindRenderbuffer(GL_RENDERBUFFER, 0);

    glGenFramebuffers(1, &backFramebuffer);
    glBindFramebuffer(GL_FRAMEBUFFER, backFramebuffer);
    glFramebufferTexture2D(GL_FRAMEBUFFER, GL_COLOR_ATTACHMENT0, GL_TEXTURE_2D, texture, 0);
    glFramebufferRenderbuffer(GL_FRAMEBUFFER, GL_DEPTH_ATTACHMENT, GL_RENDERBUFFER, rboID);
    [self checkFramebufferStatus];
    glBindFramebuffer(GL_FRAMEBUFFER, 0);

注意:如果您的版本不起作用,请确保在每次通话后检查错误并在第一次通话之前清除错误,否则您将在此之前对错误进行错误检查.
