Method psrdnoise
psrdnoise(float2, float2, float)
2-D tiling simplex noise with rotating gradients and analytical derivative.
Declaration
public static float3 psrdnoise(float2 pos, float2 per, float rot)
Parameters
Type | Name | Description |
---|---|---|
float2 | pos | Input (x,y) coordinate. |
float2 | per | The x and y period, where per.x is a positive integer and per.y is a positive even integer. |
float | rot | Angle to rotate the gradients. |
Returns
Type | Description |
---|---|
float3 | The first component of the 3-element return vector is the noise value, and the second and third components are the x and y partial derivatives. |
