As Qt developers know, in new Qt version, Qt 3D has been extended a lot. QtDataVisualization, Qt3DCore, Qt3DExtras and so on are the new examples have recently been added in Qt.

Because there are only a few examples of 3D, I ask about that. I have in mind to draw a 3D visualization of cylindrical trajectory as shown in the picture. Is it possible in Qt? Is it worth to spend my time to learn that?

由于Open Asset Import Library (Assimp)是 Qt3D 的一部分，因此您绝对可以导入各种 3D 格式。

如果你想创建圆柱体或类似圆柱体的东西，那么这个例子https://doc.qt.io/GammaRay/gammaray-qt3d-geometry-example.html非常有启发性。
