Henry,
Good to hear from you!
Could be interesting. From my reading, HDF5 just uses standard ZLIB
compression (ZIP, GZ) [
https://support.hdfgroup.org/HDF5/faq/compression.html]. I suppose there
might be some difference with that and its alternative SZIP, but I don't
find any comparisons for that with a quick search.
>From the blog comment, it looks to me he is talking specifically about
volume rendering, which is not what JVXL is for, and which Jmol is not set
up to do. JVXL is specifically for surface rendering, where it reduces a 3D
data problem to a 1D problem, thus the huge 300+:1 efficiencies relate to
cube files.
