Qt Quick3D custom geometry from 3D array

  • Hello there,
    I have some segmented medical image in DICOM format that I would like to display with Quick3D. I read those images with ITK and there is a image to mesh filter which I should be able to use. My question is how do I create a 3D object from this mesh? I found the custom geometry example, but don't really understand it as I have a limited knowledge about 3D graphics. Any help would be very welcome.

    I already have a QML file that can display a 3D image from a mesh file.

        id: displayImage

        height: 800
        Rectangle {
            width: parent.width
            height: parent.height
            Rectangle {
                height: parent.height-60
                width: parent.width
                anchors.top: parent.top
                // content
                View3D {
