Hey!

How do I choose between OpenGL and Direct3D? I'd like to make cool looking 
3D-games, which I can run on my PII 400mhz (32mb nVidia Graphics)!

Thanks

Add the line:

system("PAUSE");

just before the return 0

and the program will pause so you can see what is going on.

The problem is that your program executes and ends so quickly that you
probably just don't see it.
try this:
 
#include <iostream.h>
#include <stdio.h>
 
int main()
{
    cout << "Hello" << endl;
    getchar();
    return 0;
}
 
The call to getchar will make your program wait until you hit Enter before
it terminates.

Hiya Simon,

Threads are essentially separate sequences of execution within a program
that (at least at a high level conceptually) can be operating at the
same time.  In a more "traditional" program, for example, if you wanted
to read information to a file and display something else on the screen,
you had to do them one after the other.  Either you read from the file
and then do the screen display or the other way around.  This is because
a "traditional" kind of programming paradigm had a single "thread of
execution" in the program...  Only one thing can happen at a time.

With a multi-threaded application however, your program can do (again,
at least at a high level conceptually since a single processor can only
do one thing at a time) several things at the same time.  You can, in
essence, start one thread and tell it to do the file manipulation while
another thread does the screen display.  Think of this as the
application level equivalent of an operating system that permits
multiple users work at the same time.

What multi-threading tricky is that the individual threads in a given
application all operate on the same process space...  meaning that they
all share a significant resources.  Thus, each thread has equal access
to global variables, static class members etc...

Hi!

I've made a scene with a big box, in which you can walk around. On my friends 
machine (with a nVidia TNT2 Ultra 32mb AGP) it runs perfect in 1024x768 32bit 
with fog, and everything. But, on my machine (same CPU, but with a nVidia 
VANTA 32mb PCI) it runs REALLY slooow. Like, 5fps or so in 640x480 16bit NO 
fog and NO blending!! :(
What's wrong??
Dosn't my graphics-card support OpenGL, or am I missing some drivers or what??

Thanks!!

I'm just finishing a course on 'C' before I move onto 'C++' and I've found
that collecting functions into a library helps me stop repeating the same
functions over and over again. As an example, lets say you create a function
to uppercase the letters of a string, you really don't want to keep writing
the same function over and over again in different programs.
Not only that, it's easier to debug and read your code, changing things in
the main() could cause other errors, but change the code in a function and
you only affect the code in that function. So I would say listen to your
friend, he's come across these problems like I have and is talking from
experiance.

Very hard to establish what the problem might be given only "snippets".
However, I see one error :

        printf ("enter your choice: \n);   // no closing " before new
line. 
I would think the compiler would flag this as a parse error. If you will
attach your code we will be happy to check it.

Hi there!

I'm working with some OpenGL, as some of you might know.

I really would like to make some kind of a Doom-like engine. But, how do I 
make cameras? I've heard that cameras in OpenGL is slow, and that you therefor 
should rotate and move the entire scene. Can that be true?? Is it possible to 
rotate an entire Matrix? Like, glMatrix();

Thanks alot! :)

I can't get any GLUT tutorials to compile in Dev-C++.  I've tried
downloading libraries and dlls and headers and putting them in all the right
places.  I specify -lglut32 in the Project Options dialog, and I've even
tried creating glut32.def files following instructions from various places
I've found using Google.  No matter what I try, I keep getting "undefined
reference to glutMainLoop@0" , etc , etc , etc...

But if I copy the code over to my cygwin installation, I can compile from
the command line there and everything works fine.

Any tips?

That's CERTAINLY NOT OF ANY USE!!! ;)
First of all, it's not so simple to get HW accel. under VooDoo1/2. VooDoo
cards have their standalone OGL drivers, so glaux doesn't work with them.
You need your own texture loading routine. I'm just working on a texturing

If you divide time up into small piece's like threads in a piece of cloth
you will understand threads concept.
A program runs along a time line. (thread) The OS controls the scanning
of the threads. You can set threads in c++ to describe how your time line
should run. Not a very good explanation . Hope it helps.

Hey Guys,

I am a beginner in C++ and have a question not related
to programming :

1)I recently upgraded to WinME and have errors with
Dev-Cpp, I am going to download it again but how do I
uninstall it first ?

2)this is more like a suggestion -- would it be
possible to edit these mailgroup messages a bit? I
would like to keep them for reference but some of the
messages have huge amounts of html formatting
information

I tried this and the application totally hosed Windows 95 and I had to
reboot.  Is this common?  All the OpenGL tutorials I've used off the web
work ok in windowed mode, but fullscreen messes everything up.  Well, they
almost always work ok, sometimes closing an OpenGL program causes Explorer
to crash and everything in my system tray disappears.

Hi,

I have never used the Dev-CPP debugger or debugging facilities so I am
sorry if this is a nonsense. However, it might be the compiler uses
registers for i and f. Try to get addresses of these variables, for
example

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

int main(int argc, char *argv[])
{
  float f;
  char string[34], ch;
  int i;

  scanf( "%lf %d", &f, &i); /* ADD THIS LINE */
  f = 2653.1456;
  itoa((long)f,string,10);
  i = strlen(string);
  printf("Decimal point is %d places", i);
  i = i*10;
  f = f/i;

  return 0;
}

This should force the compiler to create them in memory.

Your friend is steering you in the right direction. You do not need to go 
overboard and have everything in functions. As the programmer, it is up to 
you to decide if a function can better suit the situation. The overall 
concept to think about is code reuse. For example, think about a function 
that adds 2 numbers. You could declare this function as a void and just 
have it cout the result, or you could declare the function as an int and 
have it return the result and do the necessary cout in the main.
