How do i get glClearColor() to work?
Changing the values in mi code has no effect, what am i doing wrong?

Method F3DInit:Int(width:Int=800,height:Int=600,depth:Int=0,mode:Int=0,rate:Int=60)
		If depth = 0 Then depth = 16
		If mode = 0 Then depth = 0
		GLGraphics(width,height,depth,rate,GRAPHICS_BACKBUFFER|GRAPHICS_DEPTHBUFFER)
		
		glClearColor(1.0, 0.0, 0.0, 0.0)
		'F3DClsColor(255,0,0,0)
		'F3DColor(0,255,0)
		
		glClearDepth(1.0)
		'glEnable(GL_CULL_FACE)
		glMatrixMode(GL_PROJECTION)
		glLoadIdentity()
		gluPerspective(45.0,Float(width)/Float(height),0.1,width)
		glMatrixMode(GL_MODELVIEW)
		glLoadIdentity()
		
		Return 0
	End Method

glClearColor(1.0, 0.0, 0.0, 0.0)
glClearDepth(1.0)
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) ''this does the actual clearing
