Scilab Function genfac3d - compute facets of a 3D surface
Calling Sequence
- [xx,yy,zz]=genfac3d(x,y,z,[mask])
Parameters
- xx,yy,zz
: matrices of size (4,n-1xm-1). xx(:,i) ,yy(:,i) and zz(:,i) are respectively the x-axis, y-axis and z-axis coordinates of the 4 points of the ith four sided facet.
- x
: x-axis coordinates vector of size m.
- y
: y-axis coordinates vector of size n.
- z
: matrix of size (m,n). z(i,j) is the value of the surface at the point (x(i),y(j)).
- mask
: boolean optional matrix with same size as z used to select the entries of z to be represented by facets.
Description
genfac3d computes a four sided facets representation of a 3D surface
z=f(x,y) defined by x, y and z.
Examples
t=[0:0.3:2*%pi]'; z=sin(t)*cos(t');
[xx,yy,zz]=genfac3d(t,t,z);
plot3d(xx,yy,zz)
