The goal is that it should be possible via Qt Design Studio to do everything you need to set up a 3D scene. That means being able to visually lay out the scene, import 3D assets like meshes, materials, and textures, and convert those assets into efficient runtime formats used by the engine.
Therefore, we also have some stand-alone utilities for converting assets. Once such tool is the balsam asset conditioning tool. Right now it is possible to feed this utility an asset from a 3D asset creation tool like Blender, Maya, or 3DS Max, and it will generate a QML component representing the scene, as well as any textures, meshes, and materials it uses. Currently this tool supports generating scenes from the following formats:.
Thiswould generate a file called MyTestScene. Then you can just use it like any other Component in your scene:. We are working to improve the assets generated by this tool, so expect improvements in the coming months. In addition to being able to generate 3D QML components from 3D asset creation tools, we have also created a plugin for our asset import tool to convert existing Qt 3D Studio projects. Note however that since the runtime used by Qt 3D Studio is different from Qt Quick 3D, not everything will be converted.
It should nonetheless give a good approximation or starting point for converting an existing project. We hope to continue improving support for this path to smooth the transition for existing Qt 3D Studio users. The first question I expect to get is why not just use Qt 3D? This is the same question we have been exploring the last couple of years. We intended to and started to do this with the 2. However, Qt 3D's architecture makes it difficult to get the performance we needed on an entry level embedded hardware.
Qt 3D also comes with a certain overhead from its own limited runtime as well as from being yet another level of abstraction between Qt Quick and the graphics hardware. In its current form, Qt 3D is not ideal to build on if we want to reach a fully unified graphics story while ensuring continued good support for a wide variety of platforms and devices ranging from low to high end.
At the same time, we already had a rendering engine in Qt 3D Studio that did exactly what we needed, and was a good basis for building additional functionally.
This comes with the downside that we no longer have the powerful APIs that come with Qt 3D, but in practice once you start building a runtime on top of Qt 3D, you already end up making decisions about how things should work, leading to a limited ability to customize the framegraph anyway. In the end the most practical decision was to use the existing Qt 3D Studio rendering engine as our base, and build off of that.
This release is just a preview of what is to come. The plan is to provide Qt Quick 3D as a fully supported module along with the Qt 5. For the Qt 5 series we are limited in how deeply we can combine 2D and 3D because of binary compatibility promises. With the release of Qt 6 we are planning an even deeper integration of Qt Quick 3D into Qt Quick to provide an even smoother experience.
The goal here is that we want to be able to be as efficient as possible when mixing 2D and 3D content, without introducing any additional overhead to users who do not use any 3D content at all. We will not be doing anything drastic like forcing all Qt Quick apps to go through the new renderer, only ones who are mixing 2D and 3D.
