How do you find if a point is inside a cube?
As maxim1000's answer shows, you can simply check if X, Y, Z coordinates of the point in consideration lie in the minimum and maximum of the X, Y, Z coordinates of the Cube. If the aforementioned condition is satisfied then, the point lies inside the cube, otherwise it does not.
How do you check if a point is inside a 3d box?
One method that can be used to check if a point is inside any enclosed, non-self-intersecting shape in any number of dimensions is to draw a line in any direction away from the point and count the number of times the point crosses the boundary. If the line crosses an odd number of times the point is inside the shape.
