<br>
</div>Only the density field. But yes, that's currently how it works for<br>
*many* of the frontends. (A few have slice capabilities.) We *do*<br>
have the ability to overload these operations in the future, but right<br>
now the IO gains have not been enough to justify the added complexity.<br></blockquote><div><br></div><div>Ok, I will do some benchmarks and test.<br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<br>
</div>For now, for GDF, I'd say 2.x. I think there are still loose ends for<br>
GDF in 3.0, but they're release blockers. So it'll be up to par, it<br>
just isn't yet.<br></blockquote><div><br></div><div>Interesting.<br><br></div><div>OK so at the moment my frontend really just has to be an extension of gdf, it needs to expose a couple of extra things out of the file and define a few derived fields. <br>
<br></div><div>I still really do not know where to start with the frontend, what are the key components of a frontend and what are it's tasks?<br><br>Stuart<br></div></div><br></div></div>
