We also included the GLUT header, which is guaranteed to include " glu.h" (for GL Utility) and " gl.h" (for Core OpenGL). The header " windows.h" is needed for the Windows platform only. GlutMainLoop() // Enter the event-processing loop GlutDisplayFunc(display) // Register display callback handler for window re-paint GlutInitWindowPosition(50, 50) // Position the window's initial top-left corner GlutInitWindowSize(320, 320) // Set the window's initial width & height GlutCreateWindow("OpenGL Setup Test") // Create a window with the given title * Main function: GLUT runs as a console application starting at main() */ GlBegin(GL_QUADS) // Each set of 4 vertices form a quad GlClear(GL_COLOR_BUFFER_BIT) // Clear the color buffer (background) // Draw a Red 1x1 Square centered at origin GlClearColor(0.0f, 0.0f, 0.0f, 1.0f) // Set background color to black and opaque Whenever the window needs to be re-painted. Call back when the window first appears and
