Nothing gained. There are two cases where app developers want precompiled shaders. The first, and most important, is for embedded environments. You really don't want to have to compile shaders on your G1 or iPhone. The other case is to implement a compiler cache. In both cases, after compiling the program, you get back a token telling you what format it is. You resubmit that token along with the compiled blob. If the driver doesn't like the token or the blob, it rejects it. When it rejects it, you have to resubmit the source (i.e., just like now). In the usual case where the user doesn't change hardware or driver, the cached blob just keeps on working. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkk/BBcACgkQX1gOwKyEAw8idwCdE2FdGBqxfPUyRTOtergkapp+ 7IwAn21A7MWOf2Dabi5VxHYtazFklGsr =X+wK -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
