want to learn graphics

[Unregistered]

hello,

i am very comfortable programming in C for DOS, using the lcc-win32 compiler for windows. i dont know anything at all about graphics programming but i want to learn. i have heard lots of mumbo about graphics libraries and all this vga and stuff but i dont know what any of it means if anyone could give me some raphics programming tutorials that go from absolute graphics beginner up to enough for me to create a little tetris-like game id be EXTREEMELY grateful

thanks in advance,

A search for graphics on these forums or www.google.com will probably give you quite a bit to look at.

Doing some tutorials in OpenGL is a good place to start as you can create programs in windows console mode without having to worry about the Win32 API. Lets you concentrate on the actual mechanics of graphics programming.

I would recomend starting with the GLUT libraries, you can find links to this with installation instructions and even some tutorials at OpenGL.org

Also I believe the OpenGL red book is available free online (not sure where). It is not the current edition as this is still available in a retail version, but it should still be relevant - there may be a link of the OpenGL site too. This is a great book and is written by the OpenGL architecture review board.

Hi,
This is written in Turbo-C:

/* Program to draw a Circle */

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{

/* request auto-detection */
int gdriver = DETECT, gmode, errorcode;
int midx, midy;
int radius = 100;

/* initialise graphics and local variables */
initgraph(&gdriver, &gmode, "");

/* read result of initialisation */
errorcode = graphresult();
if (errorcode != grOk) /* an error occurred */
{

printf("Graphics error: %s\n", grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
exit(1); /* terminate with an error code */

}

midx = getmaxx() / 2;
midy = getmaxy() / 2;
setcolor(getmaxcolor());

/* draw the circle */
circle(midx, midy, radius);

/* clean up */
getch();
closegraph();
return 0;

}

Install an old version of Turbo C++ and take a look at the all the examples in the provided help.

Get borland and use MDL, the best for everything dos related. Mouse, easy interrupt hooking, pc speaker music, your mom, tons of graphics modes up to 1024x768x16m (m as in million), keyboard routines, gui routines, and so much other stuff (did I mention your mom)

first of all be sure whether u want to learn graphics seriously or just for fun .If u want to study serious graphics then u require understanding of basic mathematics,plus study OpenGL libraries.
U can get them from the opengl web site
