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?

thanks. found it. ill give it a try and see how it works. from the documentation it seems like this is the 3d equivalent of inpolygon. do you know if there is a 3d equivalent to imrect() (in order to draw the cube volume of interest to be the input to the file you mentioned from file exchange).

I looked for the 3d version of inmrect when I saw your question but could not directly find something,
