param3di(2) Scilab Function 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 observa-
tion point
leg : string describing the caption for each axis, the different
fields in the string are separated by the symbol @, for
example : "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 right button to exit.
For Pos and Fig drivers plot3di works just like plot3d
Enter the command param3di() to see a demo.
