- Alternative C2P Routines v1.0 for Gloom Deluxe 4 Jan 1996
- ----------------------------------------------
-
- This archive is intended to be used with the wonderful Gloom Deluxe
- Demo by Mark Sibly of Black Magic Software. Hopefully it also works
- with the full commercial version of Gloom Deluxe.
-
- The files in this archive may be distributed anywhere provided they are
- unmodified and are not sold for profit.

-
- A feature of Gloom Deluxe Demo is that users can write their own
- chunky to planar (c2p) routines for Amiga native displays. It is
- possible to make Gloom Deluxe Demo faster on some machines.
-
- This archive contains some c2p routines that I wrote. They supplement
- the c2p/blackmagic_1 routines supplied with Gloom Deluxe Demo.
-
- Note: there is little point in using these routines if you have a
- 3rd-party graphics card and cybergraphics.
-
- c2p/020_1 is optimised for 68020. The routines for a pixel width of 1
- are about the same speed as blackmagic_1. However the routines for
- double-width pixels are twice as fast when 32-bit chipmem is
- available.
-
- c2p/040_1 is optimised for 68040 and 32-bit chipmem, e.g, A4000/040 or
- A3000+accelerator. It is up to twice as fast as c2p/blackmagic_1 on
- an A4000/040. It may be faster than c2p/blackmagic_1 on some 68030
- systems as well.
-
- c2p/akiko_1 is optimised for 68020+akiko, e.g, a CD32. It is 3 or 4
- times faster than c2p/blackmagic_1, but it requires an Akiko chip and
- kickstart 3.1.
-
- Note: Although my c2p routines are up to several times faster than
- c2p/blackmagic_1, the difference may not always be noticeable because
- Gloom spends only a fraction its time converting chunky to planar.
