% ex11_unit_ball.m — Uniform tetrahedral mesh of the 3-D unit ball (distmeshnd).
%
% distmeshnd is the general N-D mesh generator; here it fills the solid unit
% ball (signed distance sqrt(sum(p.^2,2))-1) with a uniform mesh at edge
% length 0.2. The plot shows a cut-away (p(:,2)>0) of the tetrahedra.
