I can make simple spirals using Filter > Distort > Twirl.
But how do I make a complex spiral like this one? The rays initially spiral clockwise, then change direction towards the end of the picture. In addition, the center of the spiral - the vortex - disappears, hidden by the rays.
Is that something you can do with Photoshop ir Illustrator's default settings? Or do you need a plugin? Or is it something you have to do manually?
Wow that is quite complex! I don't think I could do that. If anyone is going to be able to help it is our Dave
I tried Free Transform > Warp > Twist, then cropped to move the centre towards the bottom right corner and FT'd >warp > Twisted again, but mine is UGLY!!!
Maybe some sort of weather event modeling software that runs on a Super Crey (Dave is currently building his own Crey, but COVID — and the US military — are slowing the process)
That's a nice try. 😉

For those kind of complex twisting shapes I tend to turn to 3D software.
Just for demo, I started with a simple radial made in Photoshop by making triangle shapes and repeat transforming the rotation around the centre.
I then imported it into Blender 3D as a plane. I subdivided so that the plan was made of many faces. Then I just twisted the mesh by selecting a small face in the middle and moved and rotated it, using proportional editing so that nearby faces twisted on a scaled basis.
Rendered it looks like this. You can twist/untwist however you choose.
Wow, thanks for the tip. I'm going to give that a try.
