the improvements which I spontaneously like to collect here, jumping to my eye or mind, are
(a) rotation center:
The center of rotation currently seems to be hardcoded 0/0/0.
I would better like to have it at the model's center, like in LDView.
Using the mouse currently in your web app feels so different than LDView,
that it confuses me. I would love to see a big similarity in mouse handling between the 2 tools.
(b) incremental parts display:
perhaps it is very easy to do, and you could show the model already while it is loading.
the user can watch the downloaded parts appear in the model.
I think it could be quite cheap to do, because you already know all the matrices etc, just the "real" part data is missing.
Thus, you could already build up the necessary data structures, and skip them on rendering, while the model is not fully loaded.
I think this would be an evern more "incremental" load than displaying the progress status message
© mousewheel:
I am missing the use of the mousewheel for zooming...
(d) default color 16:
Nicola, you seem to currently use 0/0/0 always for default color 16.
I would prefer if you would use the color specified explicitly in LDConfig.ldr (some "medium" default grey).
To you already use that file? You can always get the most recent version also from the ldraw.org site.
(e) edges:
you currently are not rendering edges at all.
I would like to have a checkbox or button for toggling that on and off.
It should be nearly trivial to add the drawing of them to your existing implementation.
