Gael, Thanks very much for your patience, you were correct, i was building my structured grid in the wrong 'axis order', and hence the implicit connectivity was all over the place and in my inexperience i interpreted the bad result as indicating it maybe wasn't possible.
following the example where the points for the structured grid are added in order of each z-plane (previously they were by x, then y, then z) i am now back on the right track, with volume stuff working. cheers muchly, -i Le 22/06/2011 10:49 AM, Gael Varoquaux a écrit : > On Wed, Jun 22, 2011 at 10:36:40AM +0200, Ivan PRICE wrote: > >> Thanks Gael, i realise this must be pretty basic stuff for you.
