Is QQuickFramebufferItem the C++ equivalent of QML's Canvas 3D?

问题

What I want is a way to create a Qt Quick item drawn using custom OpenGL code. I seem to have found 2 ways:

• Subclass QQuickFramebufferItem and write my OpenGL code in C++
• Create a Canvas3D item in QML and draw to it from Javascript

Do these two ways really have the same purpose, with the main difference that they're used from different languages?
