Scilab Function param3d - 3D plot of a parametric curve
Calling Sequence
- param3d(x,y,z,[theta,alpha,leg,flag,ebox])
Parameters
- x,y,z
: three vectors of the same size (points of the parametric curve).
- theta,alpha
: real values giving in degree the spherical coordinates of the observation point.
- leg
: string defining the captions for each axis with @ as a field separator, for example "X@Y@Z".
- flag=[type,box]
: type and box have the same meaning as in plot3d:
- type
: an integer (scaling).
- type=0
the plot is made using the current 3D scaling (set by a previous call to param3d, plot3d, contour or plot3d1).
- type=1
rescales automatically 3d boxes with extreme aspect ratios, the boundaries are specified by the value of the optional argument ebox.
- type=2
rescales automatically 3d boxes with extreme aspect ratios, the boundaries are computed using the given data.
- type=3
3d isometric with box bounds given by optional ebox, similarily to type=1
- type=4
3d isometric bounds derived from the data, to similarilytype=2
- type=5
3d expanded isometric bounds with box bounds given by optional ebox, similarily to type=1
- type=6
3d expanded isometric bounds derived from the data, similarily to type=2
- box
: an integer (frame around the plot).
- box=0
nothing is drawn around the plot.
- box=1
unimplemented (like box=0).
- box=2
only the axes behind the surface are drawn.
- box=3
a box surrounding the surface is drawn and captions are added.
- box=4
a box surrounding the surface is drawn, captions and axes are added.
- ebox
: used when type in flag is 1. It specifies the boundaries of the plot as the vector [xmin,xmax,ymin,ymax,zmin,zmax].
Description
param3d is used to plot a 3D curve defined by its coordinates x,
y and z.
Use param3d1 to do multiple plots.
Enter the command param3d() to see a demo.
Examples
t=0:0.1:5*%pi;
param3d(sin(t),cos(t),t/10,35,45,"X@Y@Z",[2,3])
