If i can then how can i control them? for example, enable a layer of texture or disable them in real time with a script?
It’s very possible you’re just looking for a projector … check it out.
(it’s so easy to use there really aren’t many questions here about it; google for 18,000 tutorials.)
OP, it’s common that people here ask seemingly incredibly complex questions (i.e., “how to write a shader,” “how to generate mesh on the fly by hand within the frame,” etc) whereas the OP is actually looking for something super-simple (in the examples, “change an object” or “move something”).
(On that latter one it was once “scale! something” 
)
