-Message-Text-Follows- There is a way to get 4096 colors on screen at once with no limitations in high res. It requires a hacked up video cable, three Amigas, and two genlock, but some people already have that :-> The Idea is to use the one Amiga without a genlock as a master, and use the other two synced to the first Amigas video (via their genlocks) as slaves. Use the green output from the master, the red and blue from the slaves, and connect them all to one monitor. Use a paint program on each computer in high res with the palet set to a 16 level grey scale and start painting. It's a bit inconvinient since you must use a different mouse for each color, but you are getting 4096 colors in high res, and you don't even have to interlieve bits in the bit planes like HAM-E :-> If you want to get fancy you could write your own paint program which used a serial, parallel, or joystick port network to controll the slave computers so you would only need to use one mouse. Speaking of a new graphics format, There seem to be a lot of those lately Dynamic HAM, Dynamic High res, Ham-E, etc. Perhaps rather than making the editor or slide show program know how to handle all of these, we could make it possible for the program, if it did not understand a new format, to come up with a reasonable approximation of the image. If a block in the IFF file contained code in a high leval interpreted language (say based on C) to convert the bit plains included in the IFF file into a 24 bits/pixel bitmap. The program could then take this bitmap and convert it into something it can handle. This has the side benefit of alowing other machines to save in the IFF format useing whatever bit maping is convienient to the particular machine, and still being able to display an approximation of that picture on any other machine that has an IFF viewer which handles the code block.

If any of you have the Triangle Mega-demo (German?) there is one demo in which the author claims to allow over 29000 colours on screen by a tech- nique called Horizontal Colour Selection. Anyone know about this? How the h**l does it work? -- -- # J.Gold | mapjilg@uk.ac.bath.gdr # # University of Bath , UK | jilg@uk.ac.bath.maths #

WOW, WHAT A CONCEPT! Maybe we can get Black Belt Video to do this. Take 3 or 4 Amigas and hook them together so that the RGB signal from the first 3 gives you 36 bit color which is displayed on the monitor of the 4th Amiga. Then we could link them together via network and use AREXX to do the communications between the 4 paint programs which are running to display a single picture. How much do you think this would cost? probably $2000 plus the price of your favorite model/flavor of Amiga. 3 A500s, 3 cables, one mixer box would probably be able to do it. Naahh.... I think I will wait for an A3000. If it doesn't significantly improve the graphics, then I may have to look elsewhere for my NeXT computer. 8^) -- Bill Murphy murphy@newton.physics.purdue.edu

Bart Whitebook did this in the lab, with one amiga generating each of synchronized R, G, and B. You can even use "broken" genlocks because you don't use their composite conversion or switching, just the sync part. )3 or 4 Amigas and hook them together so that the RGB signal from the first )3 gives you 36 bit color which is displayed on the monitor of the 4th Amiga. I don't know what the 4th amiga is for, but you don't get 4096**3 colors, you get 4096, with each amiga spitting out one of sixteen intensity levels of its assigned color. Anyway, that's the easy way (let the monitor do the mixing). )Then we could link them together via network and use AREXX to do the )communications between the 4 paint programs which are running to display )a single picture. It would be easier to do a slideshow. Developer prices of refurbished A1000's are real cheap. You'd probably want to throw the whole thing in a box, maybe bring out six joystick ports for "special applications" ;^) )Naahh.... I think I will wait for an A3000.
