What does a "mesh" mean to you in this context? It would help if you could post a link to an example of what you would like the output to look like.

I =imread('pic.bmp') ;
[y,x] = find(I==0) ;
[m,n] = size(I) ;

[X,Y] = meshgrid(1:n,1:m) ;

idx = knnsearch([X(:) Y(:)],[x y]) ;

Z = ones(m,n) ;
Z(idx) = 0 ; 

pcolor(X,Y,Z) ;
