Re: [Openexr-devel] OpenEXR in OS X 10.4 ?

Drew and all,

Apple has announced the 30" Large flat display, requiring the NVidia 
GEForce 6800 card.
Apparently the GEForce 6800 card is going to be supporting OpenExr 
half-16-float format,
according to rumors.  Of course, ILM worked with NVidia on the 
half-16-float format.

As for which OS-X version, or which version of the 6800 NVidia card 
driver, I would also
like to know.  I would also like to see the half-16-float format 
supported directly to the
screen (with appropriate scaling and gamma controls, like the Photoshop 
OpenExr plugin).
I presume that the highest performance path to the screen will be 
OpenGL, but perhaps
there will be a faster way to write to the screen without tearing, with 
double (or triple)
buffering, and with keep-time picture sync and audio sync.  The 
"throw-it-to-the-screen-
whenever-you-have-it" mode limits the quality of moving images played 
out.  This becomes
even more challenging for bandwidth when 16-bits per color is used 
instead of 8-bits (although
I presume the 30" display itself is still 8-bits as the previous 23" 
Apple HD Cinema display).

I am hopeful that the "movie mode" screen sync will be taken seriously 
when OpenExr
is supported for 24, 30, 60, and 72 frames per second image update and 
sync'd image refresh.
