I had this incredible idea and i dun know how to implemnt it.
I want to create an external graphics card(i have no idea how to make 1) attached via USB port which can run games(not the current released versions but games made for this graphics card) ppl with sh***y graphics card would not have to waste money on new cards. Although they will not be able to play new games made to run on Nvidia/Ati graphics card.
The biggest problem i'm facing now is how to display all these 3d calculations of images or models onto the desktop.

Well, no, that's not your biggest problem.
This post has nothing to do with this forum, that's problem 1.
A USB port is not fast enough to run a high speed 3D card, that's problem 2
You want people to buy a special card, then buy games especially for this card, rather than wasting money on a new card ? Buy a new card to avoid spending money on a card ? That's a doozie.

Well it says graphics i tried the harware forum but no one replied. Well if such a portable graphics card was made computer manufactures can make a special USB port for this kind of thing
Well some awesome ps2,xbox360,wii games cant run on a PC if ppl are prepared to pay a few hundred $$ for these machines i bet they will want this portable grahics card. And about speed did u know the PSP's Microprocessor runs at 333Mhz and yet its able to play those high end games.Xbox360 runs on a P3 processor.
These usb powered games will be far cheaper and p i s s nvidia and Ati off cause they cant cheat us by placing less math formulas in the piplines

And how would using USB prevent this?

I guess they were just shaking their heads.
Sorry, but what you're suggesting is impractical, and ludicrious.

Why will they ? You barely know how the parts work, how do you propose to know what they cost ?

Why do u keep crticising this idea although i dun care.

So what if its impractical, and ludicrious. u have no proof that it cant be done.
The computer system is an example

OK. You're going to put a high-end 3D graphics engine in an external device. That means packaging, additional hardware to manage the USB interface, and a power supply.
You're also replacing an internal graphics card, which sits on a bus, with an external device that communicates over USB. The only way that the external device could possibly display things fast enough is if the data on the bus is in the form of a display command set. You could use a representation of GDI/GDI+, OpenGL. The external device therefore has to have the intelligence to interpret the display command set and execute in on its 3D graphics hardware. You've added another processor to manage the display command handling.
Like Chris said, the idea is impractical and ludicrous. Making a graphics device an external adapter doesn't gain you anything.

Sounds ambitous mate,
There is no advantage of having a graphics card outside your computer, and like Christian said the USB ports will not be able to transfer data fast enough to make it worthwhile.
If you wanted to try and design one, I would definatly encourage you (you'd be in a 100K+ job in no time if you could). But I suspect you might get a shock with the complexity of the electrical engineering involved - which is a lot harder to get to grips with than programming is.
Cheers,

They do make a special port that can handle the demands of high speed graphics. Its called PCIX, its quite wide and they put it on very very short wires right next to the CPU and RAM, so they can get high speeds out of it.
A PC has the power to run playstation & xbox360 games, its more that its easier to write games for one set of hardware.
The USB powered games will be far far shittier. They will have terrible graphics compared to anythign else on the market.
Other people have tried to provide a "better game" if you buy the hardware. Ageia did this with physics accelerators. Hardly anyone bought them, so nobody really made games for them.
Seriously, I bought a 9600GT the other day for around AU$150. How cheap did you expect to make this for?

What a great idea! And with that bandwidth you could have such popular titles as Pong 1D, and Line 1D. 3D and VR are overrated, lets get back to the meat and potatoes of games!

If we know how to do it, and there's a ton of money in doing it, why would we want to tell you?

1st i dun plan on making money its for my own interest
2nd If u knew how to do it u wouldnt be posting in this forum cos u could be in ur private boat partying
3rd i hate it when graphic companies make small tweaks and give their graphics card fancy names and pictures
4th Because of this closed secretive process, better graphical wonders are not possible to attain

I come vastly closer to knowing how to do it than you apparently do. I also know what it would take to make it viable commercially which you're apparently totally unaware of. And if I chose to put the effort forth to make it happen, I live in Silicon Valley and all the needed assests are in my backyard.

How do you know I'm not? The San Francisco Bay is lovely this time of year.
Oh, by the way. No one appreciates the dumb assed text speak you're using. It just makes you look stupid.

This is already being done by companies. It is a cool idea, but it has its limitations, and isn't practical for high end gaming.
Check out this article on Toms Hardware.com: http://www.tomshardware.com/reviews/vidock-expresscard-graphics,1933.html[^]
Basically, I would look into this solution to be able to drive a 30" monitor from my laptop for software development.
As some other posters have replied, the bandwidth of the USB port is not capable of driving a high performance graphics card for current technology games at the rate the current cards are capable of processing. The bandwidth of the device referenced in the article is about 2.5 GBits/s, which ends up being close to the equivalent of the ancient AGP 1.0, about 1/8 of the AGP 8x standard which has been out the door for quite some time.
Also, it was described that you would be running a video card, through a usb connection, and connects to the bus of the machine. Normal video cards sit right on the bus and have direct contact with the CPU and hardware. With an external solution, they cannot be as efficient because you are introducing new layers into an existing system, and will have bandwidth restrictions.
Hope this helps!

my friend and i developed a code using VB.net 2005 for Generating a flowchart for a given source code and approximatly every thing is fine but there is problem with the Dynamic relations between the nodes; they disappered when we make minimize then maximize for the window. so if some body have any idea about this problem please help coz this is our graduation project.

You know, you provide so little information in your original question, it's impossible to know. The only thing that I can suggest is that, when you resize a window, the system sends a WM_PAINT message to your window. If you think of that as an event, you can write a handler method that will redraw those connecting lines (or whatever is necessary). I code in C++, so I won't include a code snippet, but, it is a trivial effort.

Thanks a lot for your answering my question, but you are saying that I didn't write enough info. About my problem so what info. Do you suggest on me to include for making my question clearer, beside I’ll be so grateful for you if you include a code snippet even if it had been written in C++, I can handle it. Thanks again for answering

You didn't tell us anything about how you've structured your program or the data you want to display. You need to capture the data you want to display and keep it available to your program. Maybe the "Form" but I don't do VB, only C++, so I'm not sure of that terminology. The program has to be structured so the data can be displayed entirely from the data structure in response to a WM_PAINT message. I think in VB you have a paint handler function where you need to do this (OnPaint?). It sounds like you aren't accounting for drawing your "dynamic links" there. A common mistake is to let the user draw interactively on the window and not capture the data into a structure for redisplay. In your case, you get a WM_PAINT message, at least under the covers, when you restore the main window from being minimized.

norxnor,
Yes, the way Tim just stated the problem is correct. Even though we code in C++, the windows object model is the same (but, the syntax is very different). We have no idea if you are drawing to a form, as in NET Framework or a normal window (Win32). We have no idea how you did the previous drawing operation, or where you derived the data. It never hurts to provide lots of code, and describe your thinking as if we were from another planet.
Essentially, Tim is correct about preserving the data structures that your drawing code depends on. How is that done? What kind of a presentation are you ultimately trying to achieve?

Baltoro,
Maybe you should have replied to Norxnor instead of me, you're preaching to the choir. We might have scared him off and he won't see your reply.
