If that's >not what it means, then my understanding of bitplanes is way off, and >someone should explain it to me. 24 bitplanes means it has 24 bits of information per pixel. It also however implies something about the memory organisation. 24 bit color does not imply 24 bit planes. People who do not know about graphics hardware internals may use the two interchangeably. Thats because from a user's standpoint, there is no difference, both will produce identical output. But basically 24 bit color is a generic term to describe all 24bit true color architectures and 24 bitplanes is a subset of those using a planar memory architecture (with no difference in output). Hope this clears things up. %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% % ` ' Mark Thompson CONCURRENT COMPUTER % % --==* RADIANT *==-- mark@westford.ccur.com Principal Graphics % % ' Image ` ...!uunet!masscomp!mark Hardware Architect % % Productions (508)392-2480 (603)424-1829 & General Nuisance % % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
