Hi there,
now there is a new development line coming up I wanted to throw in some
thoughts which would be interesting to know for further development of
OSG (way beyond 2.7.x) and some of the infrastructure. As you might know
I am working on osgSWIG and osgART and a handful other software projects
which are used on client systems - so deployment and stability is one of
my main concerns.
- documentation, there are numerous additions recently and in the past
like osgWidgets or osgManipulators which are very interesting but not as
interesting to reverse document the code - at least a "real" API
documentation would be sufficient
- examples: I am also partly teaching computer graphics and an augmented
reality class which heavily rely on OSG. One of the problems I see the
students facing is that some of the examples are actually applications
and seem to have started simple and went off to show the most convoluted
brain-jogging way to achieve something simple - van der Rohe: Less is More
On the deployment and integration side:
- API additions which change ABI are not documented well: with osgSWIG I
am basically poking in the dark, waiting for SWIG to cough up the changes
- do I assume right/wrong that API change involves an increment in
SOVERSION, it would make backwards compatibility easy
And now the more deep down things, which I think would be interesting to
look at in a long term plan:
- with the Mac OS X 10.4 - 10.5 disaster it should be clear that one
can't assume a certain implementation of OpenGL available and relying on
it on the front-end
- this leads unevitably to OpenGL 3.x and OpenGL ES 2.0 (what happened
to the investigation of this?) on the horizon - which hints for hidden
backends as with ES there is no certainty of the actual implementation
of parts of the API - so you might need to roll your own depending on
the hardware detected
- bundling math includes in one header to be able to exchange some
implementation (ie. floating point emulation)
Sorry for the lengthy email. Objective is to get some discussion in the
OSG community - so please throw in you 2ct :)
Cheers,
Hartmut
