param3di(2)

NAME
param3di - parametric curves in 3-D with interactive view selection

CALLING SEQUENCE
param3di(x,y,z,[theta,alpha,leg,flag,ebox]

PARAMETERS

x,y,z
    : three matrices of the same size (considered as vectors with the fortran storage convention) (points of the parametric curve)

theta, alpha
    : gives the coordinates in spherical angle of the observation point

leg : string describing the caption for each axis, the different fields in the string are separated by the symbol @, for exemple : "X@Y@Z"

flag =[type,box] :
    where type and box have the same meaning as in plot3d

ebox
    : a vector of size (1,6) which gives the boundaries of the plot [xmin,xmax,ymin,ymax,zmin,zmax] when the value of type is 1

DESCRIPTION
Draw the 3D curve f(x,y) and allow the user to change the view with the mouse : Pick a point within the graphic window (Left mouse button) and drag the mouse (theta increases for left to right move and alpha increases for down to up move). When view is ok click with the left button to have the surface drawn. click rigth button to exit. For Pos and Fig drivers plot3di woks just like plot3d

EXAMPLE
enter the command param3di() to see a demo
