Philippe,
Impressive plugin. Thanks for the work! A few comments, perhaps bugs(?)
The pre-defined shape 'coquille' is the basis for all lamellibranch and
brachiopod shells, so mostly the bivalve class. I think the name should be
changed to 'lamellibranch', as more specific.
Maybe a bug: when changing parameters in, for instance, coquille, and
switching then to ammonite, the shape inherites the changed parameters (at
least it looks so when viewing the wireframe which is not the basic shape
anymore). As far as I can tell, this only happens to the ammonite. All other
selections show the basic one. Deleting the shell and restarting the plugin,
of course shows the correct ammonite shape.
Maybe another bug, I am not sure: Several times while changing parameters,
Moray froze. Only way out was ctrl-alt-del and restart Moray, although the
mdl was corrupt sometimes and had to be deleted before (due to the crash
exit, no doubt). It may be that the freeze happened because of an
incompatible parameter value (too high for instance) so that the wireframe
update took too long or was not possible.

That's it for now,

Thomas
