Cocos3d line glow effect

I am using cocos3d 7.0 (i.e. the 3d extension for cocos2d) on iOS 3.1, which only has GLES 1.1.

I want to draw a line in space with a radiant effect. Ideally, it should look like a line in the second image in Opengl ES 1.x a luminous effect in iOS . But the above example uses simple gl calls, and no cocos3d / 2d code calls are made.

Is there a good example or tutorial on creating such an effect in terms of cocos3d api?
