Cirrus Clouds

Clouds are of different types
1) cirrus
2)stratus
3)cirrocumulous
4)cumulus
5)cirrostratus

So  after working with satellite  clouds i tried to develop a tool that  can create Cirrus kind of clouds.
Cirrus clouds are very less dense ,thin,wispy and have a swirling kind of shape.
they often look very feathery and have hairy edges.

Cirrus is a Latin word which means "Curl".
     As usual i displaced the volume using a turbulent noise through a transformation matrix.We use transformation matrix  to scale, translate and rotate the frequency and amplitude of the turbulent noise.
     Then to achieve the swirling effect i used a curl noise which drives the rotate parameter of the  transformation matrix.
      To get the turbulent edges ,a turbulent noise is added which will drive the offset of the main turbulent noise.
still m unable to achieve the  hairy curls......
