digitalmars.D - openSceneGraph under D ?

does anyone know if there is a D Port of the OpenSceneGraph Project?
link: http://www.openscenegraph.org/projects/osg

that would be so cool to have under D.

I agree, it would be very nice to have a D port of the OpenSceneGraph Project or OpenSG. (http://opensg.vrsource.org/trac/wiki/OSGComparison) Bindings would be problematic since D cannot easily interface to C++ (using a C layer). Porting is a big cake of work, but I would like to contribute the translation of a file or two. :-)

Try bcd.gen; it says it's able to create a C go-between to enable interfacing with C++ code. Not sure how effective it is, but it's worth a try (loads easier than porting, anyway).

Given the size and complexity of OSG, I don't think any automated 
solution is going to be sufficient. besides, while OSG is quite handy, 
they made some rather dubious design decisions, and it doesn't feel very 
nice. Perhaps a more modern visualization framework would be a better 
choice for development in D.

Really? Like what? I haven't seriously looked at OSG for years, but I was under the impression that it was one of the better managed and designed open source projects out there. --bb

I don't deny that it is well managed, and even well designed. But I find 
it suffers from a rather 'monolithic' philosophy (how many distinct 
database formats are really useful in one app?). It also has a more 
immediate issue as regards to porting to D, namely that the platform 
interface for every platform (and API) is a separate module, each 
written in the native language and API - which would require us to 
maintain all of them.

It also relies heavily on community plugins to provide advanced 
functionality, and these are very varied in quality and completeness, 
and would also have to be ported separately - this includes most of the 
windowing toolkits, physics integration, terrain support and character 
animation toolkits.

I certainly won't argue with you about porting OSG to D.  That would be 
one hell of a job.

But it seems like for C++, OpenSceneGraph is still a pretty good option.
