Is raycasting possible?

[Stingaaa]

I am currently trying to get a point in the xyz scene based on where i clicked on the screen.
I now have a working function which casts a correct ray but I am currently facing a problem with the intersection.
It seems like the object that gets intersected is the same as the "Selection Box" when I click an object.
Therefore I wanted to ask if it is possible to get the intersection exactly where the object is, if so, could I get an explanation/ example so I can implement this?

Here's an example for a plane, which I use for my neural network visualization, here: https://github.com/emer/emergent/blob/main/netview/events.go -- see LayerUnitAtPoint, which takes an image point and returns the x,y coordinates in the plane. The core code is here:

ray := lo.RayPick(pos)
// layer is in XZ plane with norm pointing up in Y axis
// offset is 0 in local coordinates
plane := math32.Plane{Norm: math32.Vec3(0, 1, 0), Off: 0}
pt, ok := ray.IntersectPlane(plane)

lo is an xyz.Solid

Basically, the math32.Ray object has all the methods you might need to find more specific intersections.

Thank you very much for the reply.
I wasn't able to look at it today, but I will try it out tomorrow.
I will mark this as the answer for now, as I believe at a first glance that this will help me solve the remains of my problem.
