Hi That frustum is just a group of lines in cube shape, you see it as a frustum because the camera is in perspective mode.I never used Qt3D so cannot help with scene3d. But in quick3D that would be done with a class derived from QQuick3DGeometry with primitives set to lines "setPrimitiveType(QQuick3DGeometry::PrimitiveType::Lines)"to construct a cube. Then register that class to qml and use it in your View3D. Hope it helps.

Can you let me know how it can be done? If I have to get the custom QML ,do I have to get it from the C++ and then push it to the QML context? Any pointers to basic code is appreciated.
