plot3d2
plot3d2 — plot surface defined by rectangular facets
Calling sequence
plot3d2(X,Y,Z [,vect,theta,alpha,leg,flag,ebox])
plot3d2(X,Y,Z, <opt_args>)
Parameters
| X,Y,Z | : 3 real matrices |
| vect | : real vector |
| <opt_args> | : This represents a sequence of statements key1=value1, key2=value2,... where key1, key2,... can be one of the following: vect (see above), theta, alpha ,leg,flag,ebox (see plot3d) |
Description
plot3d2 plots a surface defined by rectangular facets.
(X,Y,Z) are three matrices which describe a surface.
The surface is composed of four sided polygons.
The X-coordinates of a facet are given by X(i,j),X(i+1,j),X(i,j+1),X(i+1,j+1).
And similarly Y and Z are Y and Z coordinates.
The vect vector is used when multiple surfaces are coded
in the same (X,Y,Z) matrices. vect(j) gives the line
at which the coding of the jth surface begins.
See plot3d for a full description.
Examples
u = linspace(-%pi/2,%pi/2,40);
v = linspace(0,2*%pi,20);
X = cos(u)'*cos(v);
Y = cos(u)'*sin(v);
Z = sin(u)'*ones(v);
plot3d2(X,Y,Z);
