Yes, the best way to have a indepdent object is to start from a begining.

Lets say we have set 0,0,0 as the center of the screen in the projection matrix.

Try this setup should draw in the center of the screen:
void Draw_scene(void)
{
glClear (GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); //Clear the screen
glMatrixMode (GL_PROJECTION); // Tell...
I maybe did not understand you question fully.
There are many factors that effect where an object is drawn on the screen, from the projection setting to the matrix calls like glTranslate.

I am not sure about borland C++ 3.1, but you can download like 5.0 or greater for free and it has openGL support.
Also you can download DEV-C++ by Blood Shed software for free. I have a link on...
You can reset the matrix by using glLoadIdentity() each time you move an object with glTranslate.
By that not the best way, since will work correctly if you are using a camera.
Better is to use...
Most C/C++ compilers out there today have openGL library's and can be used to create an openGl program.

Borland's C/C++

Also other languages have...
Take a look at some of the examples on my website

The clock example is a good example of creating a object from openGL primitives.
I have a simple 3D clock on my web site

If you have to use BMP files you can create two versions of the BMP file.
One is the image and the other is the transparentcy mask.
You load the first image as a RGB and the second as the Apha...
Did you tell DEV-C++ to use the openGL librarys when running the linker?
Look under project options, linker settings and add:
-lopenGL32 -lglu32 -lglut32(if you use glut)
DEV-C++ comes with all the headers needed to compile a openGL program (gl.h, glut.h, glu.h).
The files are located in the DEV-C++ directory under INCLUDE/GL/
You should be able to compile most...
No you use GLUT in place of GL AUX, most websites have examples using GLUT. nehe.gamedev.net
I have not used the GL aux with DEV-C++, but I noticed that the glaux.h header is missing from the...
The AUX library is out of date, use GLUT library instead.
Did you include the -lglaux in the linker command, that would case you to get an error on those commands?
But anyway the AUX library is...
OpenGL does not have its own compiler, it is a graphics API, written using the C language.
To compile a openGL program, all you need is to choose what languge you want to use and a compiler with...
Are you using the openGL library that came with DEV-C++ or did you download one from somewhere else?
DEV-C++ librarys look like this:
libopengl32.a
DEV C/C++ comes with the needed openGL headers and librarys.
Please list what headers you are missing?
I have the setup for using openGL under DEV C/C++ on my website to make sure you have...
I have a some examples using these shapes on my website. www.angelfire.com/linux/nexusone

Did you mean the following:

OpenGL uses floats because your 3D world is created using vectors and because the math required to create a 3D world.

What function are you using to draw the teapot?
This example will work under any C/C++ compiler:
glPushMatrix();
glTranslatef( 0,0,0); // location of first teapot

Look's like a build error durring the linking of your library files.
Are you compiling a using the Microsoft windows API or using something like the GLUT api?
If you are using a GLUT based...

Use glutTimerFunc, and you can set the time interval that you display is updated.
And is not effected by CPU speed.

OpenGL.org set's the standards, but it is up to the OS maker and video card maker to write librarys and video drivers that are compliant.
It would be a real task for openGL own its own to try and...
Just to use it for openGL applications, make sure you have the newest version of your video drivers. Example: ATI has its openGL video drivers in the same install as the direct X ones.
Nvidia also...
