Using a thread for drawing cubes with OpenGL...how?

Hi everyone,

I've created a program that uses threads to process the images and points (which are centers of cubes)

I would add a low priory thread that uses OpenGL functions to draw the cubes as they have them processed, through the centre and size, using "wiredCube"...I'm just not very good with OpenGL, but I have read various articles here and looking on google: all the examples I find are with "mainloop" in the main, in charge of launching the various drawing functions of OpenGL...

Instead, how can I do to have a simple function of three-dimensional design, which is updated every few time, with the cubes refreshing, with just a simple thread?

I'm on Visual C++ and a 64bit app. I've read that I need freeglut to use 64bit libs...

Please, someone could show me how?

A piece of code of my program is this:

#include <windows.h>
#include <process.h>


....
variables, others..

int main(){

	HANDLE handle0,handle1,handle2,handle3,handle4;
  
	//threads
	handle0 = (HANDLE) _beginthread(puts,0,&dati0);
	handle1 = (HANDLE) _beginthread(grey,0,&dati1);
	handle2 = (HANDLE) _beginthread(soglia,0,&dati2);
	handle3 = (HANDLE) _beginthread(finitura,0,&dati3);
	handle4 = (HANDLE) _beginthread(verifica,0,&dati4);

	//join
	WaitForSingleObject(handle0,INFINITE);
	WaitForSingleObject(handle1,INFINITE);
	WaitForSingleObject(handle2,INFINITE);
	WaitForSingleObject(handle3,INFINITE);
	WaitForSingleObject(handle4,INFINITE);

..other code...
...

}

I need to insert a "fifth" thread that do 3D drawing, in low priority (background)...

Please, help me.
