V3.2 FUSION Video Drivers

Latest update on the video drivers for FUSION v3.1 for the Amiga.


Description of direct drivers:

amiDirectXL - B&W direct driver for those cases where a B&W driver
is needed.  Uses the Amiga blitter when blitter acceleration is
enabled.

cgxDirectXL - Compatible with CGX V2 or V3; designed for use
as the ONLY display on the video card.  Will probably look
bad if more than one program is trying to use the card (that
includes Workbench!).  Uses video card blitter when blitter
acceleration is enabled; the blitter should be disabled if using
one of the older cards (Picasso II, Piccolo, and Spectrum).

cgx3DirectXL - Requires CGX V3 r70a; will work with multiple
screens on the card as long as dragging is turned off.  Uses
video card blitter when blitter acceleration is enabled; the
blitter should be disabled if using one of the older cards
(Picasso II, Piccolo, and Spectrum).

sd64DirectXL - Based on the cgx3DirectXL driver; it has the
thousands modes removed so that the card may be used on the
PiccoloSD64 in 256 color and millions mode.  It will also
work on the CV series as well.

p96DirectXL - Picasso96 API driver; will work with multiple
screens on the card.  Uses video card blitter when blitter
acceleration is enabled; the blitter should be disabled if
using one of the older cards (Picasso II, Piccolo, and Spectrum).

All direct drivers (except amiDirectXL) require the Memory
Mapping to be enabled to do more than 256 colors.


Description of refreshed drivers:

amiRefresh - Works with OCS/ECS/AGA machines; uses the MMU
to speed up the refresh if the Memory Mapping is enabled.
Uses HAM8 on AGA machines to do thousands and millions modes.
For best operation, have the DBLNTSC, DBLPAL, MULTISCAN, and
SUPER72 monitors in your monitors drawer.

amiQDDRefresh - Like the amiRefresh driver, but uses Quick
Draw damage rectangles to speed up the refresh; it does not
use the MMU, but will not work with programs that access the
MAC display directly.  This is the driver you would use on
an EC processor if you don't have a video card.

amiTVRefresh - By popular request... a driver that does
NTSC and PAL High-Res, Super-High-Res, High-Res Overscan,
and Super-High-Res Overscan.  If you don't like the positioning
in overscan modes, just drag the screen to a better position.
This driver is strictly for those people who requested it for
video work from FUSION.  It WILL flicker unless you have a
flicker-fixer/scan-doubler hooked to your Amiga video output.

CD32_QDDRefresh - This driver is designed for people using
a CD32 with the SX expansion.  It uses the AKIKO to refresh
the display and has limited modes to keep memory useage down.
It uses Quick Draw damage rectangles and will not work with
programs that access that MAC display directly.

CD32_DQDRefresh - Based on the CD32_QDDRefresh driver, but
refreshes the entire display at one tenth the set refresh
rate; this allows it to be used with programs that access
the MAC display directly.  It also uses QD damage rectangles
at the set refresh rate so that programs that use QD refresh
normally.

cgxRefresh - Allows the use of thousands and millions modes
on any CGX supported video card.  Uses the MMU to speed up
the refresh if the Memory Mapping is enabled.

cgxOverlay - Uses the CGX video overlay feature of the
CV3D and CVPPC to display the MAC in a video overlay window
on Workbench, as long as WB is on the video card.  Uses
QD damage rectangles.

p96Refresh - Allows the use of thousands and millions modes
on any Picasso96 supported video card.  Uses the MMU to speed
up the refresh if the Memory Mapping is enabled.

p96PIPVideo - Uses the P96 video overlay feature of the
CV3D and CVPPC to display the MAC in a video overlay window
on Workbench, as long as WB is on the video card.  Uses
QD damage rectangles.

wbwRefresh - Displays the MAC in a window on Workbench;
allows millions mode if WB is on a video card and in either
thousands or millions mode.  Uses QD damage rectangles.


Notes about v3.2:

Added two new drivers: sd64DirectXL and amiTVRefresh.

Took the opportunity to fixed a minor bug that is in all
the previous video drivers.

Fixed cgxOverlay to work with latest library; due to the
new method of handling access to the overlay memory, the
driver is now too slow to be useful (thanks Frank :^{ ).

Fixed a race condition in the bitplane clearing in the
amiDirectXL driver; you should no longer get partial screens.
