face3
Examples
Create an untrimmed triangular patch in the plane, y=1.
f1 = face3([0 1 0]',[1 1 1]',[0 0 1]');
Create a circular face as a trimmed patch in the plane, z=0.
f2 = face3(circ2(0,20,10));
A patch that can constitute the wall of a cylinder, is created by setting the control
weights explicitly, as in the command below.
f3 = face3([-1 -1;-1 -1;0 0],[0 0;-1 -1;-1 -1],...
[0 1; 0 1; 0 1],[1 1;1/sqrt(2) 1/sqrt(2);1 1]);
To generate a third degree rectangular patch, the following commands can be given.
[x,y] = meshgrid(-3:3:6,0:2:6);
z = rand(size(x));
f4 = face3(x,y,z);
