Hi,
I'm new to Delphi and got Delphi 3.0 profesional edition for me to learn, I wanna create a fast graphics program under Win95. I need to put a lot of pixels in whole screen within 1-10 milisecond, so since it won't possible in normal Win95 API, I guess I should use DirectX, but the problem is I dun know how to start with and how to create it ??
Please anyone know how exactly to create a simple pixel uses directX help me...
Please tell me detailed what I really need and what should I do since I'm newbies :) if allowed please create a ready to compile sample source pleaseeeee....

Hi Mirek,

I thought there's a misunderstanding about my question, what I really mean is how to fill the whole screen for example 640*480 16 million color with pixels which each pixels color and coordinate calculated lately, but the important thing is that I need pixels can fill whole screen only within 1ms, so each 1ms the screen change into another pixels fill if possible without flickers :) thanks for your comment and help I hope you can help me a lot

I can do this with SetDIBits and BitBlt (640x480) in 8,8ms so I think this can't help you?

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

This time depend on hardware. I have 486 with 160Mhz and S3Trio VGA card with 2MB RAM. If you have Pentium 100 with better VGA i think so this can work faster.
Mayby you need learnig DirectX not fast writing to screen ?

Thanks for your help mirek,
If you sez that 8ms for filling the screen, I thought that's enough for me, but if it was 88ms, I thought it's too long and I need better refresh then that because I need to accurately update the graphics each 1ms if possible because the result of the graphics is used for controlling other purpose, this displaying it self not yet computed so I hope to get a very fast filling methode, because before fills I need to calculate each pixels location and color to determine the process later...
You're right about hardware dependencies, I need to run it on 486-100 processor with only 16Mb RAM and win95, so I hope that you can help me determine which way the best I do with it in Delphi.
If possible please teach me DirectX way of it, also tell me is it still possible in DirectX ??

I saw some SVGA cards with special drivers (MATROX ...) which can do this very fast but i think so in standard SVGA card (as my S3Trio) DirectX can't do this in needed time.

I don't have any directX template but i write any example to you later (1-2 day ).

Mayby in this time another expert write any code for you.

Regards
Mirek

Hi mirek,
Thanks a lot for your help so far, I do hope that you can make me a way to learn directX way of putting pixels or bitmap or whatever needed not need 3D since I just need a 2D way to representing graphics. I really appreciate if you can help me on it thanks.

If I were you I would first go to Blake Stones homepage.
http://www.dkw.com/bstone/
And then maybe try Delphi Game Creater homepage:
http://www.users.dircon.co.uk/~zeus/
These are 2 good sites!!!! Because learning Delphi AND DirectX can't be descriped on such a site like this!!!
