poi matrix

poi(s) matrix vol(id)

       Returns the point s of volume id transormed by its matrix.


poi menu("MEN")

Returns the points list of menu MEN.

poi menu("MEN")=x1,y1, x2,y2,...

Changes these points.
The listis of the form {xai,yai,xbi,ybi}0 < i < n (n = number of boxes).
       xai,yai,xbi,ybi = coordinates of top-left corner and bottom right corner of the box i.

poi obj(id)=x,y,z

        Changes these points.

poi(num) obj(id)

        Returns the coordinates of point num de of object obj id.

poi(num) obj(id)=x,y,z

        Changes this point.

poi(0) obj(id)=x,y,z

        Adds the point (x,y,z) to object id of type obj.

poi mouse
