.TH genfac3d 2 "October 1995" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
genfac3d - compute facets of a 3D surface
.SH CALLING SEQUENCE
.nf
[xx,yy,zz]=genfac3d(x,y,z,[mask])
.fi
.SH PARAMETERS
.TP 10
xx,yy,zz
: matrices of size (4,n-1xm-1). \fVxx(:,i)\fR ,\fVyy(:,i) and \fVzz(:,i)\fR
are respectively the x-axis, y-axis and z-axis coordinates of the 4 points of
the ith four sided facet.
.TP
x
: x-axis coordinates vector of size m.
.TP
y
: y-axis coordinates vector of size n.
.TP
z
: matrix of size (m,n). \fVz(i,j)\fR is the value of the surface at the point
(x(i),y(j)).
.TP
mask
: boolean optional matrix with same size as \fVz\fR used to select
the entries of \fVz\fR to be represented by facets.
.SH DESCRIPTION
\fVgenfac3d\fR computes a four sided facets representation of a 3D surface
\fVz=f(x,y)\fR defined by \fVx\fR, \fVy\fR and \fVz\fR.
.SH EXAMPLE
.nf
t=[0:0.3:2*%pi]'; z=sin(t)*cos(t');
[xx,yy,zz]=genfac3d(t,t,z);
plot3d(xx,yy,zz)
