- CyberGfx is an RTG solution. Without RTG, ANYTHING AT puts into the Amiga
- will be outdated and irreplacable in a matter of months.
-
- RTG provides a means to upgrade graphic hardware without losing prior
- compatibility AND easy access to new functions.
-
- For simplicity, let's say there's and RTG function called "draw_cube" -
- it uses the 680x0 and draws a cube to your current graphic chipset
- whatever that may be (ECS, AGA, Picasso, CyberVision, etc.) - well, when
- new cards come out with processors *on* the video card for accelerated 3D
- graphics, ALL your programs will automatically use it since the driver
- will now reference the gfx card's processor instead of the 680x0. You may
- have a function that automatically texture maps your objects - one driver
- might use the blitter/copper/cpu depending on what your computer has. The
- programmer only needs to use the "texture_map" function or arguments. If
- you had a 3DO chipset, the driver would leave your blitter, copper, and
- cpu alone and use that. If offers complete flexibility to the user and
- his/her configuration while not bothering the programmer with having to
- support many different standards.
-
- The way it's been done, ALL the software would have to be rewritten to
- take advantage of the new gfx coprocessor, and not only that - the
- software may not even work at ALL! Amiga can't survive like that in a
- market where everyone else is (almost) painlessly evolving.
-
- Amiga NEEDS RTG. Whether it's specifically CyberGraphX or not is another
- question, but it's currently the strongest looking contender.
-
- (of course it would need ECS and AGA drivers to support the enhanced gfx
- functions for machines without gfx cards.)
