- Short: v.fast c2p converter (cpu+blitter) 020+
- Type: dev/src
-
- c2p4.a (written by Peter McGavin) is a 4-plane chunky to planar covnverter
- optimized for 020+ systems with fast mem. It uses a comparison buffer (ie.
- convert only what has changed from the previous frame). Performs the first
- two passes with the CPU and then passes 3 and 4 with the blitter. Returns
- immediately after starting the blitter (ie. your program can calculate the
- next frame while the blitter is still running).
-
- An example of the speedup possible is demonstrated with wolf3d.old and
- wolf3d.new - use the joystick to move around and fire to exit.
-
- wolf3d.old was taken from the wolf3d-2.lha archive, and was written by
- russell@cpsc.ucalgary.ca (Terence Russell) using a "normal" c2p converter.
-
- wolf3d.new was modified by peterm@maths.grace.cri.nz (Peter McGavin) using
- the new c2p4.a converter
-
- Enjoy!
