Comparison of Qt 3D and Qt 3D Studio

In short, Qt 3D Studio is built on top of Qt 3D. The flexible architecture of Qt 3D makes it suitable to build 3D runtimes, or engines, such as Qt 3D Studio.

Qt 3D

Qt 3D is programmer-oriented engine building toolkit and great for both simple and complex scenes. Qt 3D simplifies the implementation of advanced rendering techniques.

Qt 3D Studio

Qt 3D Studio consists of both a 3D editor and a 3D runtime. Qt 3D Studio is designer-oriented and makes it easy to build complex 3D scenes with states and transitions that can be used in and controlled by Qt applications.

Use Case Comparison

Whether you should use Qt 3D or Qt 3D Studio for your project depends on your use case. Below, we list some common use cases and how they apply to the two:

Creating 3D Scenes

Use CaseQt 3DQt 3D Studio
Graphically editing a 3D scene for use in a Qt application.No built-in editor. Support for importing common 3D formats.Yes, use the Qt 3D Studio Editor.
