I am an Engineer/Researcher. I recently graduated from UCF with a PhD. I wanted to showcase and give a C++ unreal engine 4 project that I used for my research. These are nice interactive geometrical diagrams. I used this even for my Dissertation defense, the committee was impressed There is also a small animation of how the grid points map from spherical to multilayered linearized setting, where Key ‘E’ starts the animation and ‘T’ reverses it. I hope this is someway useful to someone.
You can download the project from here: https://github.com/syedalamabbas/DemoPolarSphericalTransformGeometry.
For more information about the actual research work see these two repos.

Main C++ code work to generated the 3D plots is here : https://github.com/syedalamabbas/DemoPolarSphericalTransformGeometry/tree/master/Source/CppBeamEmitter/BeamWork
Here is the C++ code snippet where is generates the spherical polar grid points :
Here are some pictures that showcase the generated 3D plot:
