[Papervision3D] A* 3D, perlin noise

[joa e.]

There is always a problem with copy and paste. Life sucks :(

Actually you can achieve a perlin noise effect by simply doing a cos 
interpolation over a simple plasma. This means you have to create some 
plasmas that have different frequencies and amplitudes based on the 
number of noise octaves.
