Re: AutoOpenGl Plugin

The CPU time eater is here:

// Main routine - thread callback
DWORD __stdcall __MainLoop( void* Param )
{	
    g_WinConfig.CreateGlWindow( );

	glutDisplayFunc( __Draw );
	glutReshapeFunc( __WindowResize );
	glutIdleFunc( __Draw );
	glutMainLoop( );
	
	return 0;
}

Call of glutIdleFunc() initiates the waste action (draw) which was  
already implemented by calling glutDisplayFunc() (above). 

Description of glutIdleFunc() is the following:
http://www.opengl.org/resources/libraries/glut/spec3/node63.html

"...

glutIdleFunc sets the global idle callback to be func so a GLUT 
program can perform background processing tasks or continuous 
animation when window system events are not being received. If 
enabled, the idle callback is continuously called when events are 
not being received. The callback routine has no parameters. The 
current window and current menu will not be changed before the idle 
callback. Programs with multiple windows and/or menus should 
explicitly set the current window and/or current menu and not rely 
on its current setting. 

The amount of computation and rendering done in an idle callback 
should be minimized to avoid affecting the program's interactive 
response. In general, not more than a single frame of rendering 
should be done in an idle callback. 

Passing NULL to glutIdleFunc disables the generation of the idle 
callback. "

Simple solution to free CPU is to replace

 glutIdleFunc( __Draw );

to 

 glutIdleFunc( NULL );

Script with rendering of this sort will make autorotation the Earth 
very easy and smoothly, I think.
