Hi, I am plotting data points in 3d space. what i wish to do is allow a user to select a volume of interest. is there a function that allows to do this? I know that in 2d there are functions such as imrect() and inpolygon() that allow the user to draw a rectangle and then see which points are inside. is there a 3d equivalent to these functions?

For those who are seeking answers of the similar problems, using viewmtx to map 3d position [x y z] to 2d space is an option. Then you can solve the problem as in 2d coordinates.

imrect() works in 3d but only along x/y
