   Dirk asked:

   Now, for the bug: why don't you send out a _small reprocible example_ 

For what it is worth, on my Lintel system with homebrew install of octave-forge:

s=1000;x=rand(s,1); y=rand(s,1);tri = 
delaunay(x,y);plot(x(tri'(:)),y(tri'(:)),'*-')
s=10000;x=rand(s,1); y=rand(s,1);tri = 
delaunay(x,y);plot(x(tri'(:)),y(tri'(:)),'*-')

and even 

s=100000;x=rand(s,1); y=rand(s,1);tri = 
delaunay(x,y);plot(x(tri'(:)),y(tri'(:)),'*-')
 
work just fine as an expensive method of painting red background. 

(I know that I am not drawing the triangulation right---please enlighten me if
you can see a way to break the lines between the triangles)
