They are talking about something different than 64 bit color on your monitor. They are talking about how software can be written in 64 bit color instruction instead of 32 bit to allow more information per shader pass. The article is poorly written in my opinon and misleading. I'd like to add that any analog monitor can display an infinite number of colors. It is the job of the video card to convert the video signals fom digital to analog.
The video data is divided into 3 colors- red, green, and blue. Each color is give a brightness level in 24 or 32 bit color the level is represented as an integer from The video card takes this digital information and coverts it to analog, which the monitor can use.
In analog, you aren't limited to integers as you are in digital- you can display any color red, green, or blue at any brightness level you want. You old-timers should think about it- was your monitor rendered obsolete when 24 or 32 bit color came around?
Now, whether this will make any difference in image quality is still up for discussion. I, for one think that the frame rate hit of actually having to handle millions of times the number of colors to display will be too much for the first couple years after the technology is introduced, and even then, its iffy whether or not you will be able to notice the difference. Whoever says you cant see the difference between bit colour and bit colour is wrong and misleading.
Yes its true, bit colour has already removed the colour banning in rendering realtime but bit colour still doesnt have enough colours to display the proper image colour. To the human mind, there is no limit on how many colours there really is and how we see colour deffies on what we are looking at. Human cloneing and genitic alterations need bit colour to accuratly define two define properties visually over a small. Carmack is da man. Dont doubt one with a talent and iq twice of mine and yours.
His passion for graphics and design far surpasses mine and yours. The current name for this card is the Eclipse and wont make the market untill sometime View Profile View Forum Posts. It's really more about blending and less about being able to see the difference between 64 and If you were to present a standard 2d picture, one in 32 and one in 64bpp, I would bet that very few people could pick out the difference.
Where 64bit color does come into play is in layering. When you paste a few textures on top of each other assuming you're using some transparencies the precision of the final color is degraded with each layer. I can't believe how many people go on about adding extra colors. See fig. So we have talked of some of the advantages of 64 bit processing, but what of the disadvantages. The first is obviously size.
By doubling the number of bits used to store each pixel, twice the amount of memory is required to store it. For example, a 1k by 1k image at 32 bits would require 4MB of storage uncompressed. Using the same calculation, but with 64 bits per pixels 8 bytes the image at bit would require 8MB. The current drop in memory and disk drive prices around the world means this is not as great a disadvantage as might be expected, and if only the processing stage is 64 bit, the disk space requirements are unchanged.
Using a resolution independent paint system such as Satori negates the need for large memory requirements, with even very large 64 bit images being loaded and edited in real time.
Another perceived disadvantage of bit imaging is the added processing requirement for the extra data. Although you might expect a doubling of processor power to achieve the same results this is not the case.
Most modern processors are equally happy dealing with 8, 16 or 32 bit data lengths, with little or no degradation of performance for increasing lengths. The overheads generally are down to the added time requirements of moving larger amounts of data around the system, and can be minimal, especially in a resolution independent system. How many colors can my display show? How many distinct colors are available in the 24 bit RGB color space? What is the difference between a 8-bit and a 24 bit image?
Which is better 8 bit or 16 bit? What is 8 bit 16 bit bit? Are all jpegs 8 bit? What is the difference between an 8 bit number and a 16 bit number? Which Colour space is best for web graphics? Can a JPG be 16 bit? How do I know if my image is 8 bit? Why does making an image bigger not make it clearer?
Is 8 bit color good? Which is better 8 bit or bit? What is 4K bit? Why is 64 bit faster than 32?
