Regarding creation of a 3D Models Menu

[Jeff]

You can use texture quads placed in the world and update their positions when selections are made. Use viz.pick to help with selections. To fix the quads to the view, set their reference frame to viz.RF_VIEW:

import viz
viz.go()

viz.addChild('dojo.osgb')

positions = [0.3,0,1],[0,0,1.5],[-0.4,0,2]
lake = viz.addTexture('image2.jpg')

for position in positions:
	quad = viz.addTexQuad(pos=position,scale=[0.3]*3)
	quad.texture(lake)
	quad.setReferenceFrame(viz.RF_VIEW)
	quad.disable(viz.DEPTH_TEST)
