3D Ray Casting

Hi everyone.
I love Gideros. I like how quick you can get from an idea to actual working code. I even managed to publish a gideros-made game on the google play store a few years ago ( working html demo here: miellaby.github.io/renabomb/web/gideros.html ).
But now I need help.
I try to make a new game using the recent 3D API of the latest Gideros releases.
Here is the repo of my work so far: github.com/miellaby/hitchScratch
Despite I have no background in 3d programming, I managed to make what I wanted (luckily I had no reason to use shaders).
But now I'm stuck with a problem. I need you help.
I can't find a way to compute what is under the mouse cursor (or the user finger). I know that this problem is an application of "ray casting" but it looks like maths way too complex for my limited abilities.
So, has anyone managed to make a 3D game where the user may point things in the 3D scene?
I will be very grateful if anyone could help me.
regards

717.I am going back to it! great work!
For your information, last time I tried hitTestPoint doesn't even work in 2D (it doesn't take rotation into account). I would be really surprised if it does the job.
