Is anyone know any way to use graphics in the dos turbo c/c++, beside graphics.h? Or a way to do it in Assembler, so I can write the functions/classes myself? Thanks in advance.

Take a look through

Well, I found this tutorial:http://www.brackeen.com/home/vga/
I hope it will help other people too.

I wouldn't recommend the BGI. VESA is not well supported in real mode DOS when using XP.

To code in lets say TC++/ASM:
(I forgot how TC does Hex and I'm writing this on the top of my head)
1. Go to 13h by this code:

asm{
mov ax, 0013h
int 10h
}


Then get a pointer to the vid mem by:

unsigned char *screen;
screen = (unsigned char*) 0xA0000000;

To put a pixel:

screen[x + y * 320] = color


You could use shifts for offset calcs if speed is an issue. I have a few Tc++ 13h progs at home. PM me if you want to get them.

I have some 3d demos, plasmas, algorithmic textures, etc.

Most of them are a combo of ASM and C++, but I usually have another pure C++ version which are a lil slower than ASM+C++.

Edit:


Okay here are the source and exes. Compiled with TC++ 3.0

Enjoy!
