util-noise

A set of deterministic, pseudo-random noise generator functions.

For each function, noise generated at a given coordinate with a given seed will result in the same value every time.

Functions

Noise1D

                float Noise1D(
                  float2 coord, 
                  float iseed)
              

Description

Generate noise from a 2D coordinate and a seed.

The resulting value will be in the range [0..1).

Called by tracking-instability.

Parameters

coord

Type: float

The 1D coordinate to generate noise at.

iseed

Type: float

A seed value for the noise.

Return Value

Type: float

A noise value in the range [0..1).

Noise2D

                float Noise2D(
                  float2 coord, 
                  float iseed)
              

Description

Generate noise from a 2D coordinate and a seed.

The resulting value will be in the range [0..1).

Called by svideo-to-rgb, composite-to-svideo, and Noise1D.

Parameters

coord

Type: float2

The 2D coordinate to generate noise at.

iseed

Type: float

A seed value for the noise.

Return Value

Type: float

A noise value in the range [0..1).
