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......

Satellite Clouds

As a part of my cloud system i tried to simulate satellite clouds ,which is not that bad....but still need to implement the vortex stuff  none but the cyclone clouds ...a common stuff in weather report...

Initially i displaced the volume with  a turbulent noise through a transformation matrix and used a curl noise to drive the rotate parameter of the transformation matrix.finally another turbulent noise is used to drive the offset of the first turbulent noise.Length of the position is taken and multiplied with user parameter (displacement) which will drive the amplitude of the curl noise.
