如何在
创建窗口时启用多重采样?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问题。
诀窍是在QWindow
的构造函数中使用QSurfaceFormat
,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...
