I am looking for an example or a tutorial how pathfinding works in real 3D (x,y,z) environment. Many examples show how an enemy follows a player, but in the end this is (x,y or two axes) - so 2D pathfinding in 3D environment.
I want to make a small simple project with a closed transparent box in which an object (doesn't matter, the main thing is simple) can search for a way to any point in the available space inside the box. In the box are distributed at different positions (not only on the ground) other objects, through which the object must not fly. If the goal is reached, a new goal is given and the object searches its way through the available space again. A camera is stationary at a fixed position and watches what happens in the box.
Is something like this feasible at all and are there any examples?
I would like to learn about this and would appreciate any tips or examples.
