OutOfMemory with a mesh...

Hi,

I ve got a big problem...
When I use the same method as developped in Delaunay.main (UnionSet of
Gridded3dSet) to draw a mesh, I've got an exception
java.lang.OutOfMemoryError
It occurs when I call DelaunayCustom with about 200 000 points and 1 000
000 tetras...
It isn't a very big mesh for my application... How can I do to avoid
this lack of memory ???

Thanks
