Hi everyone, Okay, the results of the short, two-question survey are in: almost everybody that uses a Mac uses EPD, everybody else works on remote systems, and nobody uses funky-shaped/aligned covering grids. This has two upshots: 1. the GUI may start including components that utilize TraitsUI or TVTK, both of which are Enthought packages. The first will speed development time, make for easier expansion of featuresets, and enable better maintenance of the GUI. The second will allow me to wrap into the main GUI the VTK stuff that currently sits inside VTKInterface and that is currently standalone. (It's kind of simple so far; movable planes, transparent contours and camera path design.) TraitsUI would likely be wrapped into the installation script with wxPython, but TVTK would not be. 2. the covering grid will be rewritten to use integer math. This will speed thing up not just because of the math, but because of the greater number of assumptions that can be made, and thus the simplified algorithm for filling in the covering grid. Thanks, everybody! Now, for the second part. As some of you may have realized, the documentation could be improved. I'd like to put out a public call for feedback. If you could answer (off-list, private to me) the following three questions, that would be great: 1. Where would you like documentation efforts to be focused: a) recipes/scripts, b) object model description or c) tutorials? 2. Would you prefer this documentation be on a) the Wiki ( http://yt.enzotools.org/wiki/ ) or b) in the yt source distribution ( http://yt.enzotools.org/doc/ ) 3. Do you have any suggestions? (your response can be as simple a response as: ' a, b, no ' if you like) Thanks, and I apologize for filling up everyone's inboxes. The 1.5 release is not terribly far away, but an important component of that is going to be documentation, and it'd be helpful to know where to focus our efforts. -Matt
