What I am trying to reproduce in Away3D 4 is:
http://demo.bkcore.com/threejs/webgl_tron_godrays.html

Anyone got any source, demos, hints?

I have tried to make God’s ray.

But there are a wall of AGAL 200lines limit.
Making rays needs a looping rautine(expansion UV and sampleing).

The number of rautines equal ray’s number.
So, in 200lines, I have couldn’t make only 10-12 rays.
(Maybe the WebGL demo have more rays. 50, 100, 200? I don’t know.)

I wonder that one of more easy way is modifing Radial blur filter by adding threshold parameter.

Looks like there is a way to do it, just not sure if this can be mixed with Away3D 4.
