示例1: Display
/*-----------------------------------------------------------------------------------------------
Description:
This is the rendering function. It tells OpenGL to clear out some color and depth buffers,
to set up the data to draw, to draw than stuff, and to report any errors that it came across.
This is not a user-called function.
This function is registered with glutDisplayFunc(...) during glut's initialization.
Parameters: None
Returns: None
Exception: Safe

void Display()
{
glClearColor(0.0f, 0.0f, 0.0f, 0.0f);
glClearDepth(1.0f);
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
// in the absence of an actual timer, use a hard-coded delta time
gParticleManager.Update(0.01f);
// this handles its own bindings and cleans up when it is done
gParticleManager.Render();
// tell the GPU to swap out the displayed buffer with the one that was just rendered
glutSwapBuffers();
// tell glut to call this display() function again on the next iteration of the main loop
// Note: https://www.opengl.org/discussion_boards/showthread.php/168717-I-dont-understand-what-glutPostRedisplay()-does
// Also Note: This display() function will also be registered to run if the window is moved
// or if the viewport is resized. If glutPostRedisplay() is not called, then as long as the
// window stays put and doesn't resize, display() won't be called again (tested with
// debugging).
// Also Also Note: It doesn't matter where this is called in this function. It sets a flag
// for glut's main loop and doesn't actually call the registered display function, but I
// got into the habbit of calling it at the end.
glutPostRedisplay();
