Here is a small example that should provide you with enough to get started. You can use the left/right arrow keys to rotate the menu. Let me know if something is not clear.

import viz
viz.go()

import math


QUADS = 8		#Number of menu quads
RADIUS = 2		#Radius of menu
ANGLE = (360.0 / QUADS)

#Create overlay window for floating menu, with its own view/scene
menuScene = viz.addScene()

menuView = viz.addView()
menuView.setScene(menuScene)

menuWindow = viz.addWindow()
menuWindow.setClearMask(viz.GL_DEPTH_BUFFER_BIT)
menuWindow.setPosition(0,1)
menuWindow.setSize(1,1)
menuWindow.viewpoint(menuView)


#Create root node for menu quads
menu = viz.addGroup(scene = menuScene)
menu.translate(0,1.8,5)

#Create texture to apply to quads
tex = viz.addTexture('ball.jpg')

#Add each menu quad
for x in xrange(QUADS):
	quad = viz.addTexQuad(parent=menu)
	
	angle = ANGLE * x
	
	x = math.sin( viz.radians(angle) ) * RADIUS
	z = math.cos( viz.radians(angle) ) * RADIUS
	
	quad.translate(x,0,z)
	quad.rotate(0,1,0,angle+180)
	quad.texture(tex)
	quad.alpha(0.7)

#Rotate menu using arrow keys
vizact.onkeydown(viz.KEY_LEFT,menu.addAction,vizact.spin(0,1,0,ANGLE*5,0.2))
vizact.onkeydown(viz.KEY_RIGHT,menu.addAction,vizact.spin(0,1,0,-ANGLE*5,0.2))

#Add some model to the normal scene
viz.add('gallery.ive')

hye...then how i'm going to declare each menu for each different screen?
i develop a different scene on differ .py file..then, i develop one menu.py, as a main scene , i wonder why i cant link to another .py file by following the scene tutorial??

I'm sorry, I don't understand what you are asking. Can you explain it in more detail?

[cookey]

hehe..sorry...
i had create a few different scene on different file..let's say scaffold.py and planetDemo.py. Then, i create a transparent menu as i ask before. then i tried to make the button function by click one of the button, and it can link to the scaffold.py file.but the problem is, it only function with .wrl but not .py?why does it happened?
