a new 3D data transfer format released by Sony and ILM as open source. I'll be curious where this goes, I suspect it's more tailored to the large shops than the smaller, but like with OpenEXR I suspect we'll all benefit.
This link [earthtimes.org] also shows SESI is fully behind the initiative(see the provider quotes lower down) and while I wasn't there, rumour has it at the Siggraph SESI user group meeting the Alembic logo came up on a slide, so looks like we'll be sitting pretty.
Cheers,
