Alembic is an open computer graphics interchange framework. It distills
complex, animated scenes into a non-procedural, application-independent
set of baked geometric results. This "distillation" of scenes into baked
geometry is exactly analogous to the distillation of lighting and
rendering scenes into rendered image data.
Alembic is focused on efficiently storing the computed results of complex
procedural geometric constructions. It is very specifically NOT concerned
with storing the complex dependency graph of procedural tools used to
create the computed results.
OpenVDB is an Academy Award-winning open-source C++ library comprising a novel
hierarchical data structure and a suite of tools for the efficient storage and
manipulation of sparse volumetric data discretized on three-dimensional grids.
It was developed by DreamWorks Animation for use in volumetric applications
typically encountered in feature film production and is now maintained by the
Academy Software Foundation (ASWF).
OpenSubdiv is a set of open source libraries that implement high performance
subdivision surface (subdiv) evaluation on massively parallel CPU and GPU
architectures. This codepath is optimized for drawing deforming subdivs with
static topology at interactive framerates. The resulting limit surface
matches Pixar's Renderman to numerical precision.
This comes from a new upstream, that focused on moving fwbuilder from
Qt4 to Qt5. There is no other functional changes to be expected by this
update.
OK rsadowski@
letsencrypt have already stopped allowing ACMEv1 for new domain
validations, and are now doing "brownouts" for all ACMEv1 access,
disabling it temporarily twice a month for increasing lengths of
time (6/24/48/72/120/168 hours) in the run up to disabling it
completely on June 1st.
- smarter algorithm for existing files: check timestamp and overwrite if
the source file is newer
- copy constant animation delay from webp to gif (instead of setting it to 0)
