GLUT: Warning in (unamed): The following is a new check for GLUT 3.0; update your code.
GLUT: Fatal Error in (unamed): redisplay needed for window 1, but no display callback.

You need to declare RenderScene function as callback which is called by GLUT framework to redraw window:

glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB); 
glutCreateWindow("Simple");

glutDisplayFunc(RenderScene);

SetupRC();

glutMainLoop();

Don't call RenderScene directly. Read also this tutorial:
