创建窗口时如何启用多重采样?我应该如何初始化 OpenGL 以匹配?

我花了一段时间才弄清楚这个。

诀窍是QSurfaceFormat在你QWindow的构造函数中使用 a ,如下所示:

setSurfaceType(QWindow::OpenGLSurface);
QSurfaceFormat format;
format.setSamples(4);    // Set the number of samples used for multisampling
setFormat(format);       // Note we set the format on the window...
create();                // Create the window

context = new QOpenGLContext(this);
context->setFormat(format);    // ...and set the format on the context too
context->create();

稍后,在初始化 OpenGL 时:

glEnable(GL_MULTISAMPLE);    // This seems to be the default given the configuration above, but just in case that's not universal...
