_Hello, I am working with the registration algorithms that 3dslicer offers me, but I have to make it receive data from unity 3d and thus be able to calculate the transformation matrices, I don’t know if it can be done that way. Or what can you advise me?_

There have been several Unity applications (mostly intended for HoloLens) that exchange images, models, and transforms with Slicer in real-time. Most recent is by @AliciaPose et al. See for example this complete Unity app:
