This could make development difficult, however, much of the structure is deja-vu inducingly familiar to PV3D and Away3D. I've begun writing an AlternativaRenderer, but am coming across a few issues getting the Particles mapped to Object3Ds (DisplayObject3D/Containers in Alternativa's Lingo) and am thinking the better choice is the Sprite3D class. This class can be extended for multiple phases (IE a timeline) relatively easily, supports transparency and is native to the engine.

Maybe I'm the only one out here craving this confluence, but I'll post my delvings here in the hopes that some other braver and wiser soul comes across it:

I'd like to get Flint working with Alternativa3D, but it's not currently a priority for me so it's great that you're doing it. If you need some pointers, I would be very happy to make suggestions.

One thought - you'll need some Alternativa3D specific initializers to initialize the image to a Sprite3D object and to set this object's texture, similar to the classes in Flint's papervision3D initializers.

Keep posting issues and updates here and hopefully we can encourage you to keep working on it and help you out as necessary.

No 3D support but hey, I moved on to other projects, sue me :D.
There is a particle test included.
