Inverse Hyperbolic Cosine node

Access: Nodes > Math > Inverse Hyperbolic Cosine

The inverse of Hyperbolic Cosine. Acts as a sharp progreessive expander for values starting above 1.0. Input is clamped to a minimum of 1.

Input (RGB)	Output (RGB)
1.0, 1.0, 1.0	0.0, 0.0, 0.0
2.0, 2.0, 2.0	1.3170, 1.3170, 1.3170
0.5, 0.5, 0.5	(0.0, 0.0, 0.0) (due to being internally clamped to 1.0)

Inverse Hyperbolic Cosine node inputs

Input

The value whose inverse hyperbolic cosine is to be calculated (clamped internally to ≥ 1).

Inverse Hyperbolic Cosine node outputs

Output

The resulting value in the range [0,∞).
