   My own graphics library
  Hey everyone. Im not to sure if this is the right place to be posting this but I couldnt think of a better place. Ive been up all night(its 3:08am) trying to find a solution to my problem so if you cannot understand my post i will rephrase again tommorow when I am not falling asleep. Right then i took the time and dedication today of learning ASM and i have been doing really well. I have created a demo which changes video mode to number 18 (640x480 16 colours) and I have plotted a blue pixel in the center. The program runs until a key is pressed. Heres my code:;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; Pixel Plot; Matthew Henley; 29/05/2007;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;start:;Set Display Mode (18)MOV ah,00;MOV al,18;INT 10h;;Draw A Pixel At The Center (320,240)MOV ah,12;MOV al,1;MOV cx,320;MOV dx,240;INT 10h;;Wait For A Key To Be PressedMOV ah,00;INT 16h;;Switch Back To Text ModeMOV ah,00;MOV al,3;INT 10h;;Exit ProperlyMOV al,4Ch;MOV ah,00;INT 21h;Now that i have managed to do that in ASM I was woundering how would i do the same in Cpp. Without another graphics API like D3D, OpenGL, GDI. Is there a way i can get a pointer to the video memory and change the mode. Then plot the pixel.This is all just for a learning purpose as if i manage to do it in Cpp i will then be able to make a very simple primitive graphics library (pixels, lines, rectangles, ellipse).Thank you for your time and i hope you can understand. *snores and falls asleep*   
  Why do you want to stay away from Direct3D/OpenGL?  If you don't use them, you'll be relying on the software to do all of the graphics processing.  If you use OpenGL/Direct3D, it will allow you to take advantage of video hardware, making your graphics render extremely fast.   ;  You can, but you need a DOS compiler. You can't do that with a Windows executable (a console app is NOT a DOS program).There was a quite simple graphics library out there (PGE?) that provided you with a 32bit image buffer for quite a lot of OSs. This might be easier in the end and you can do low level pixel access.   ;Quote:Original post by Rob LoachWhy do you want to stay away from Direct3D/OpenGL?

I have used GDI and started with Direct3D about a year ago. Im just woundering whether it is possible for someone to create a very simple graphics API.Quote:Original post by EndurionYou can, but you need a DOS compiler.

(I have not looked into it).Could you not just inline his asm code within c++ code? (Even if it must run from DOS only).
