I want reverse(?) spherize
In Photoshop there is a filter called [Spherize].
You can adjust the convex, concave image centered on the Amount value.
I want to use these functions as shaders.
We used the shader to create a convex image corresponding to the + value in the Asset Store. https://www.assetstore.unity3d.com/kr/#!/content/25378
However, it is doubtful how to create a concave image corresponding to - value.
Positive Value
Negative Value , i want this
would like to know an expression or an algorithm that can represent such a UV.
Thank you!
