All,
I've been using Eduardo Iturrate's IDL Revolution object graphics
code generator for about two weeks now and have found it to be a very
useful tool, on a par with xobjectview. It has saved me a great deal
of time while providing valuable insight into the mechanics of writing
object graphics code. It's trivial to replace IDLgrView with
RHTgrCamera in the generated code for added versatility and
straightforward to do a first order optimization of the generated
code. Coupled with Ronn Kling's book, it provides a great way to get
started using object graphics.
Michael Galloy did a byline on Revolution back in March, but
otherwise have there has been little notice taken as far as I can tell
-- I only found one reference to it in this group and there have only
been ~180 downloads from the IDL site which I find rather surprising.
Has anyone else found it useful?
Bill

David,
OK, no mas! :) I understand that you don't believe it has much
value. However, my honest opinion is just the opposite of yours. The
code generator has been working very well for me with minimal fuss --
it really must be magic after all (?).
I am wondering if anyone else has had a chance to form an opinion.

Whoops! A little Freudian slip there. In truth, I don't
want to be mean. I'm just trying to be honest in my reaction.
If the *first* thing I try shows a basic misunderstanding of
IDL code generation, then my confidence in what comes next
is not high.
I'll probably try it again, but I'm out of the office for
a week and...
Cheers,
David

I have to admit, when I realized the very first file wasn't
even named correctly to run automatically, my expectations
were not very high. So low, in fact, that I haven't found
the time to get back to it yet. I'm mean, really, this is
a *code* generator, supposedly. And the IDL code doesn't
run automatically. Should we take bets on how well it
is going to work ahead of actually learning to run the thing?
Cheers,
David

All,
Besides the difficulties encountered finding it, any opinions on
the application?

David,
It is bizarre -- nothing found when searching from http://www.ittvis.com/idl/
but the search is sucessful from http://www.ittvis.com/codebank/index.asp
and http://www.ittvis.com/codebank/index.asp?list=bycategory& ;product=IDL.
It is only by serendipity, as opposed to the possession of a
secret, that I've been by-passing the broken search at the top IDL
page (http://www.ittvis.com/idl/) with a bookmark I put in place some
time ago. Clearly the search engine needs an overhaul.

LOL, You guys are killing me...all I can say is that a real search
engine for our website is on order :-) In the meantime, best to just
keep watching the newsgroups for all the hard-coded links back into
Code Contrib where many gems reside.
Thanks,

I think that Eduardo makes object graphics more accessible than iTools
does, but his code generator has far less features than iTools.
I remember providing feedback to ITTVIS that I would like to see a
simpler implementation of iTools with less features, but easier to
understand.
Unfortunately, I won't use his code generator for two reasons:
1) The source code is not available, so I am a little hesitant to have
my development highly integrated with something to which I have no
control.
2) The code generated cannot be easily integrated into an event driven
program. I really need access to graphics objects from outside the
scope of scg_og.
Ruby on Rails is a good example of how to use code generation
effectively. They have things called 'scaffolds' which is the default
implementation of a module. You can then generate and tweak the code
for the module if your unhappy with the 'scaffold'.
Robbie
P.S. I find navigating the codebank almost impossible. I can't even
find my own software in there!
I just keep tabs on new additions

David,
You are absolutely correct wrt any comments regarding value -- I
guess that Freudian slip thing is contagious :)
