@AndyBrice Frankly, I had a lot of familiarity with OSG - it is very mature with a lot of useful functionality built in over the years and a robust user community. For example, it is trivial to add geometry with a space-ball "navigator" and selection to highlight an object.

@SGaist Thank you, I will check it out.

Yup. You can find the packages under Pi Menu > Preferences > Add/Remove Software. Doing a search there will eventually bring up the needed modules.

I am still curious as how one builds the modules separately though.

Thanks again!

Thank you for the input, I shall dive into this.

It's been a long time since I used OpenGL.
OpenGL version 1.1 to 2.1 handle power of 2 textures.
I think it is with GL 3.0 that non pow-2 textures work. I think you have to explicitly create a GL 3.0 or above context. But I could be wrong.

Also, try making a 256 x 256 or 256 x 512 or 512 x 512 texture.

@ItzMeJP said in Is it possible to embbed a 3dscene in qml Pane (Qt.QuickControl) type?:

thank you, but it still crash my application.

What crash? You never said anything about a crash ...

Is there any problem regarding my main.cpp code?

Not that I can see.

@surajj4837 Hey, can you please provide your solution to this issue? Thank you ...

thanks for trying to shed some light on this.

As I said, I have already installed the vulkan SDK (the "official" one from LunarG as I am trying to build for windows). I have even added the include directory directly in the *.pro file, and have observed that when opening the qt3d project with QtCreator, it can correctly resolve the vulkan libraries, so I think this is not the problem. I will try your suggestion of putting the vulkan headers directly in the qt directory and see if that gets me anywhere..

Ok, I figured out how to use updateData properly. Leaving this here for posterity. For my use case, I needed to upload a grayscale 3D texture but this should be the same for any texture type:

using namespace Qt3DRender; QTexture * tex = new QTexture3D; tex->setSize(vol.width(), vol.height(), vol.depth()); tex->setFormat(QTexture3D::TextureFormat::R8_UNorm); tex->setLayers(1); tex->setGenerateMipMaps(false); QTextureWrapMode wm(QTextureWrapMode::ClampToBorder); tex->setWrapMode(wm); data->setFormat(QOpenGLTexture::TextureFormat::R8_UNorm); data->setWidth(vol.width()); data->setHeight(vol.height()); data->setDepth(vol.depth()); data->setMipLevels(1); data->setLayers(1); data->setPixelFormat(QOpenGLTexture::PixelFormat::Red); data->setPixelType(QOpenGLTexture::PixelType::UInt8); QByteArray qba; qba.setRawData((const char *)vol.dataUint8(), static_cast<int>(vol.byteSize())); data->setData(qba, 1); QTextureDataUpdate update; update.setX(0); update.setY(0); update.setData(data); tex->updateData(update); Qt3DRender::QParameter p(); p.setName("volume"); // the uniform name in the shader p.setValue(QVariant::fromValue(tex)); QMaterial * mat = ...; // queried from the qml mat->addParameter(p);

The Qt3D test for texture update was pretty helpful in figuring this out.

I have a similar problem. I get the following error message when loading a gltf file with the QML SkeletonLoader:

[Qt][Qt3D.Renderer.Jobs][2] :0 :: Unknown buffer 0 when processing buffer view

Neither self-exported files from Blender nor files downloaded from the gltf git (glTF-Sample-Models) are working.

So I also need to know how to correctly export gltf or whether further adjustments in Qt are necessary in order to make it work.

Or you can fix the macdeployqt code and build it to replace your version. That way you benefit from all the file processing done during the deployment process.
